This study explores the optimal utilization of woody biomass to support the decarbonization of hard-to-abate industrial and transportation sectors. A biomass-to-X (B2X) model was developed using mixed-integer linear programming (MILP), integrating inter-regional energy flows and high-resolution municipal-level data across 1741 municipalities in Japan. The model incorporates estimates of available woody biomass, levelized cost of X (LCOX), and spatially interpolated energy demand. The results reveal significant spatial disparities in resource availability and energy consumption. Available woody biomass ranged from 10.0 to 56.9 PJ/year, representing 1.3–7.4 % of theoretical potential. LCOX values for methanol, methane, FT-fuel, and ammonia were estimated at 144.8, 170.7, 381.1, and 228.1 EUR/GJ, respectively, significantly higher than those based on prefectural aggregation due to reduced economies of scale. Optimization results showed that methanol dominated the woody biomass conversion output, accounting for 86.1 % of the total energy produced. Regions with abundant forest resources exhibited high self-sufficiency, whereas demand-concentrated areas relied on inter-municipal integration, increasing coordination costs. Network analysis identified 32 biomass communities engaged in circular energy flows, underscoring the potential for decentralized energy systems. This study highlights the effectiveness of combining biomass energy modeling with graph-theoretic approaches to design localized decarbonization strategies.

Designing sustainable local energy systems requires addressing three aspects of the energy trilemma: energy economics, energy security, and environmental impact. These elements are influenced by geopolitical factors that exert policies over geographical locations in which the energy system operates. The geopolitics-energy nexus is typically studied in the context of global energy markets or energy challenges. However, this paper addresses the nexus from the perspective of sustainable local energy system design, focusing on the Israeli occupation's restrictions on Palestine's energy development. The methodology involves constructing an optimization model that aims to minimize annual costs while considering scenarios reflecting the occupation's restrictions. Preliminary estimations are made regarding energy demand loads and the potential supply from renewables. The assessment of renewable supply reveals promising figures for solar energy in Palestine, and demand estimations indicate that electricity consumption represents the highest demand among all energy carriers. The results demonstrate that geopolitical factors negatively impact the energy trilemma to varying degrees. Restrictions on Area C primarily affect energy security, while the West Bank-Gaza connection influences self-sufficiency and costs. Additionally, forced reliance on electricity imports impact all three pillars simultaneously. These limit the utilization of local renewable sources, thereby weakening energy sustainability. Furthermore, seasonal variations in demand intensify the impact of geopolitical factors. Integrating a 50 % electric vehicle into the transport system shows potential to mitigate these challenges, but it does not alter their effects. This research highlights the critical interplay between geopolitics and energy system design, providing insights into achieving energy sustainability under restrictive conditions.

Complex network approaches have been emerging as an analysis tool for dynamical systems. Different reconstruction methods from time series have been shown to reveal complicated behaviors that can be quantified from the network’s topology. Directed recurrence networks have recently been suggested as one of such method, complementing the already successful recurrence networks and expanding the applications of recurrence analysis. We investigate here their performance for the analysis of nonlinear and complex dynamical systems. It is shown that there is a strong parallel with previous Markov chain approximations of the transfer operator, as well as few differences explained by their structure. Notably, the spectral analysis provides crucial information on the dynamics of the system, such as its complexity or dynamical patterns and their stability. Possible advantages of the directed recurrence network approach include the preserved data resolution and well defined recurrence threshold.

Changes in the composition of the energy system Comparison with Energy Flows in 2013 A 2020 version of the current status of energy flows in Japan is shown in Figure 1 (1). Total Primary Energy Supply (TPES: Total Primary Energy Supply) for the year was 17.4 EJ (LHV basis), a decrease of 8.5 % compared to 19.0 EJ in the 2013 version prepared in 2016. Only 5.54 EJ was effectively used in the industrial, business and other, residential, and transportation demand sectors, while 9.6 EJ, or 55 % of the total, was disposed of as heat. Japan's overall net energy use ratio (total energy efficiency) is 32 %, almost the same as the previous 33 %. This is mainly due to the low efficiency of thermal power generation and the low energy efficiency of automobiles. In renewable energy, which converts power generation efficiency to 1, photovoltaic power generation increased from 0.05 EJ to 0.67 EJ and wind power generation increased from 0.02 to 0.08 EJ, but from an overall perspective, the sum of both increased to only 0.68 EJ, or 3.9 % of total primary energy supply.

Implementation of the variable and distributed renewable energy to the energy systems is an important approach for decarbonization and transition to sustainable region. The purpose of this study is to clarify the geographical distribution of renewable energy resources and energy demand, and to clarify the effects of cooperation between municipalities for introducing renewable energy. First, energy consumption and renewable energy potential were estimated for 1,741 regions in Japan. The results showed that resources and demands were geographically symmetric and unevenly distributed. Additional analysis considering regional financial capability showed that regional symmetry is more pronounced and that approximately 95% of the municipalities had difficulty implementing regional energy policies individually. We then designed cross-border regions in consideration of cooperation between municipalities with different characteristics. As a result, in the base case, 49 cross-border regions were formed by 284 municipalities, and 108 municipalities shifted to sustainable state that has sufficient renewable energy resources and financial capability

This study aims to develop a design methodology for district heating network based on linear heat density. In the previous study, district heating systems including network were designed by applying mixed integer linear programming (MILP), however, number of demands was small because MILP takes long computational time. In this study, we have designed a district heating network design as a spanning tree problem, and have analyzed it based on Prim’s algorithm. First of all, heat demand was analyzed and heat density maps in target municipals were drawn according to the geographical information of buildings, and the statistical data of the energy consumptions. The target buildings as the demand of district heating systems (DHSs) were selected from the higher heat density area in the drawn heat density maps. In the developed methodology in this study, it is assumed that the heat source is installed in the higher heat demand building. Three heat pipe networks were designed based on linear heat density (LHD case), distance (Distance case), and heat demand (Demand case), and their heat loss and cost were analyzed. As a case study, DHSs in Koriyama city and Akita city were designed and compared. The average pipe diameter and the average linear heat density in the LHD case showed similar trend to experiential curve. The trend in heat loss and pipe cost showed rapid increasing as supplied heat increased in LHD case. It can help to select demand buildings for superior performance of DHS. In the Distance case, the minimum heat loss and cost were obtained when supplied heat were higher, however, there were no clear trend in heat loss and pipe cost because they depended on demand distribution.

Fuel cell vehicles are expected to be a key actor for coming hydrogen society in Japan. However, because of different source of fuel hydrogen, there remains uncertainty of the real value of FCVs. A question arises of what is benefit of introducing FCVs compared with other passenger vehicles such as HEVs and EVs. This study investigates the characteristics of FCVs in Well-to-wheels using inventory analysis. Analytical results indicate that FCVs have an important benefit of reducing carbon emissions provided carbon free hydrogen fuel by green electricity derived electrolysis. In the total cost of ownership, price of FCVs is the dominant expenditure, which suggest the secure of FCV’s cost reduction.

In this study, we define sustainable forest utilization based on forest information and assess the productivity of harvesting process of forestry machinery for sustainable utilization of forests in the Oku Aizu region of Fukushima Prefecture. First, we look at the case of the Nishikata area in Mishima town and analyze its labor productivity. Then, we consider the adaptation of the harvesting system used in the Nishikata area throughout the Oku Aizu region and evaluate the number of personnel required for sustainable forest utilization. The productivity assessment of the harvesting system in the Nishikata area provided an estimate of 3.3–8.3 m ³/person-day in the steeply sloping forests. Productivity in the gently sloping forests was estimated to be 38–53 m ³/person-day. Sustainable forest utilization in the Oku Aizu region requires harvesting and reforesting 160–180 ha/year. The number of persons needed for harvesting in Oku Aizu was 34–110 in the first 50 years and 34–76 thereafter. Using the suggested process, productivity in the gently sloping forests in the Nishikata area was similar to that in Austria and other countries with developed forestry. Meanwhile, the productivity of the steeply sloping forests was either equal to or higher than that in Japan at present. Measures to improve productivity in countries with industrial forestry necessitate expanding the forest road network and revising working hours.

A question arises of what is benefit of introducing FCVs compared with other passenger vehicles such as HEVs and EVs. This study investigates the characteristics of FCVs in Well-to-wheels using inventory analysis and forecast penetration of FCVs into the passenger transportation sector applying an energy-economic model. Analytical results indicate that (1) FCVs have an important benefit of reducing carbon emissions provided carbon free hydrogen fuel by green electricity derived electrolysis. (2) Under the carbon reduction target of -80% in the year 2050, the share of FCVs in the passenger vehicle transportation sector reaches 14%, which is higher than 1% without carbon constraint. (3) In the total cost of ownership, price of FCVs is the dominant expenditure, which suggest the secure of FCV's cost reduction. The result of the study shows that the penetration of FCVs into the passenger transportation market requires competitive price of the vehicle as well as higher carbon reduction target.

The purpose of this study is to design a sustainable supply chain of wood biomass fuel by applying a mixed integer programming (MIP: Mixed Integer Programming). To evaluate the effect of routing choice quantitatively, two objective functions are defined; cost minimization and energy consumption minimization. In the Railway case, 4 t truck can be used to transport wood logs and pellets, and railway can be used to transport pellets. In the Heavy truck case, three types of trucks (4 t, 10 t, 20 t) can be used to transport wood logs and pellets. As a case study area, five prefectures of Japan's Tohoku region are selected. The computational result provides that supply cost becomes 17,058 - 24,773 JPY/t_pellet. In any case, since cost of pellet supply is lower than distribution price of pellet which is 45,000 JPY/t_pellet in Japan, letting break-even point to distribution price of domestic pellet, this system has competitiveness to Japanese pellet suppliers. Effective utilization rates of biomass resource through supply chain show 0.802 - 0.834 that is higher than the previous study using waste woods. The CO₂ reduction by coal substitution shows 0.967-1.029×10⁶ t-CO₂/year which shares 65 - 69 % of CO₂ emission from the coal combustion.

The aim of this study is to quantitatively evaluate the benefits of reused vehicle parts through a material flow approach. The energy consumed by new components for vehicle repairing can be saved. Moreover, an appropriate use of materials obtained from end-of-life vehicles (ELVs) contributes to waste reduction. Each reused part has different material compositions, weights, and demand; thus, the total benefit is evaluated using inventory analysis by introducing the definition of embodied energy and CO₂ emissions. The Japanese ELV market was taken as a case study, and the results show that energy and CO₂ saved by reusing parts are approximately 35.3 GJ and 1,887 kg-CO₂ per vehicle, and 111 PJ and 6 MM ton-CO₂ for the market in Japan. Finally, possible measures to boost the current benefits are discussed.

Improving national energy security has been recognized as one of the most important perspectives of energy policy in Japan. On the other hand, a notion of higher energy resilience has recently become common to make a domestic energy supply system stable since the Great East Japan earthquake occurred in 2011. Therefore, a purpose of this study is to establish frameworks that evaluate energy security and energy resilience quantitatively to design a sustainable energy system. An advanced framework for energy security evaluation is developed in which Resource Diversity, Import Price, Import Region Diversity, Environmental Impact and Energy Efficiency are selected as criteria, where each criterion is normalized between 0 (extremely low security) and 1 (extremely high security). In addition, a multi-objective analysis using the augmented ε-constraint method (AUGMECON) is conducted to determine the best energy resource configuration for a Japanese energy system from the perspective of both energy security and economic feasibility. On the other hand, energy resilience evaluations are conducted in accordance with four steps: identifying risks, assessing risks, building resilience, and evaluating resilience. Energy resilience is evaluated based on two criteria. The first one is Resilience Index which is calculated by a ratio between energy supply and energy demand. The second one is an economic loss incurred by a sudden energy supply interruption. In conclusion, in order to develop a sustainable energy system in Japan, it is important to increase the proportion of renewable energy consumption, which contributes to enhancing both national energy security and regional energy resilience.

Although pulverized coal-fired power plants are important as base-load power sources, they emit a large amount of carbon dioxide ( CO2 ). Given this, it is necessary to reduce their CO2 emissions, and co-firing with carbon-neutral woody biomass is an important measure for achieving this. However, while Japan possesses an abundance of forest resources, the actual biomass- to-coal ratio achieved in co-firing remains as low as a few calorific percent. Aiming to achieve 50% co-firing on a thermal basis, IHI has been working to verify and demonstrate the effectiveness of a comprehensive system — including the supply chain for the woody biomass — in cooperation with some universities. Eventually, in FY2015, IHI carried out demonstration experiments involving processes from logging, wood collection, processing, and transportation through to co-firing power generation at a 150 MW-class commercial thermal power plant. These experiments demonstrated that a co-firing biomass-to-coal ratio of 25% ( thermal basis ) can be achieved using purely domestic fuel.

The purpose of this paper is to analyze energy consumption and supply on a prefectural scale, and to visualize and compare the regional energy demand-supply distribution considering potential of renewable energy. The final energy consumption and the final energy consumption per capita are related to the industrial sector. Total final energy consumption is reported to be 13,297 PJ, of which 6,136 PJ is used for the industrial sector. In the residential and commercial sector, population is the most effective on the final energy consumption. On the other hand, final energy consumption per capita in residential sector is tied to the climate: cold areas like Hokkaido, Tohoku, and Hokuriku have larger consumption than other areas. Energy expenditure per capita in residential sector is also large in cold areas; for instance, 98,581 JPY/capita is spent for energy in Hokkaido. The energy supply system in Japan depends on thermal power generation that is large scale-centralized; Chiba has the largest thermal power generation estimated at 390 PJ. By contrast, thermal power generation in Yamanashi is the smallest in Japan estimated at 0.5 PJ. Renewable resources are widely distributed in Japan, but renewable energy supply which is calculated at 374 PJ is very small. Onshore wind power and solar power have enough potential, evaluated at 2,985 PJ, to substitute thermal power plants. This study indicates that development of local energy systems, especially local heat supply system, is important to introduce local renewable energy, and introduction of renewable energy leads to more balanced regional energy demand-supply distribution.

In this study, we estimate supply potential of carbon-free hydrogen from wind power in Japan using spatial information such as wind speed and the land use. Then, hydrogen supply cost is revealed for every municipality in the Tohoku districts considering hydrogen production to distribution. The estimation indicates that the supply potential of carbon-free hydrogen in Japan is as much as 205 billion Nm³/year. With that amount of hydrogen a fuel cell vehicle can drive 3,030 billion km. When a high-pressure gas transport system is used for delivery of carbon-free hydrogen from each municipalities to Sendai city, the hydrogen supply cost ranges from 159.8 to 257.0 JPY/Nm³, and the average cost is 180.6 JPY/Nm³. If all cost component of carbon-free hydrogen supply system are replaced by the future cost target, the supply cost range decreases to 82.4~137.3 JPY/Nm³ and the average cost is 99.4 JPY/Nm³. The driving cost of fuel cell vehicle by this future hydrogen supply cost ranges 5.60~9.31 JPY/km and the average cost is 6.72 JPY/km. This cost is cheaper than 7.01 JPY/km of the internal combustion engine vehicle fueled with gasoline.

 In Japan, fossil fuels imported supply about 90% of primary energy, which occurring large amount of CO₂ emission and outflow of domestic funds to other coutries. The objective of this study is to design the local energy system using local resources which can realize low emission and economic circulation in the area. The targeted area is Fukushima prefecture. First, the amount of energy resources in local area is estimated using GIS. Second, the energy system is optimized in terms of CO₂ emission and cost, then the system is evaluated from multi points of view which are economic effect, energy efficiency and resource diversity. As a result, it is concluded that if more wind energy and wood biomass used the CO₂ emissions will be decreased to almost 0 and economic ripple effect in the local area will be increased.

Hydrogen supply infrastructures such as hydrogen production and filling stations are expected to accelerate the penetration of fuel cell vehicles. This study focuses on a hydrogen material flow from the production to the consumption sector to discuss hydrogen supply potential in Japan. Both the hydrogen supply capacity and demands are investigated to estimate hydrogen sales and its self-consumption status based on the current data. The difference between the supply capacity and consumption quantity is defined as a surplus hydrogen capacity. Detailed estimation indicates that the surplus hydrogen capacity affords to supply high purity hydrogen up to 8,700 million Nm³ a year, which is equivalent to 3.3% of the final energy consumption in Japan's transportation sector in 2012.

Depending on the technology used to produce liquid biofuels, they can be classified into: first-, second-, and third-generation biofuels. The first generation uses as feedstock edible biomass such as corn and sugar cane, the second generation uses lignocellulosic biomass such as forest residues, and the third generation uses algae. The technologies employed to produce first-generation liquid biofuels are more developed and mature than those employed by the second- and third-generation. However, the fact that they use edible crops as feedstock leads to a debate about the negative impacts that this can cause in an economy, particularly over the prices of the food sector. This work joins this debate by analyzing the economic impacts that introducing ethanol produced from rice can cause in the Japanese economy. A comparative-static, multi-sector, Computable General Equilibrium (CGE) model is used to execute the analysis. The model simulates a neoclassical economy where producers maximize profits subject to technological constraints, and households maximize utility subject to budget constraints. It incorporates intermediate demands, has a government and an investment agent, and includes the rest of the world interacting with the economy through exports, imports, and transfers. Different case study scenarios have been set based on two criteria: the bioethanol production process and the gasoline-ethanol mix ratio. Among the bioethanol production processes, an only ethanol production system, and an ethanol and power production system are considered. For the gasoline-ethanol mix ratio the model includes a biofuel penetration rate parameter that represents how much of the gross output of the gasoline sector is replaced by the new biofuel. We run various simulations for different values of this biofuel penetration rate parameter (in a range from 5% to 85%) with the intention to cover all the common ethanol fuel mixtures standards. The relevance of the study is that understanding the consequences of introducing biofuels into an economy is crucial to be able to design a supportive policy that helps to enhance the positive effects and decrease the negative ones.

The purpose of this paper is to estimate the feasibility of a low-carbon society in Japan through developing an energy flow, carbon flow and cash flow. In addition to total primary energy supply (TPES) and final energy demand, the energy flow contains estimated renewable energy potential, energy services and energy losses. TPES in 2012 is estimated as 18.9 EJ, of which 17.9 EJ (= 17.9 ×10¹⁸ J)was supplied by fossil fuels. Total renewable energy potential is estimated as 21.2 EJ which is enough to meet Japan's TPES. Wind energy has large potential of 18.3 EJ. As for demand sectors, the transportation sector has the largest energy losses, 2.62 EJ, due to low energy efficiency. Total CO₂ emission in 2012 was 1,223 Mt-CO₂, of which 956 Mt-CO₂ was emitted from both coal and petroleum. Coal is mainly supplied to electricity generation sector, and petroleum is supplied to transportation sector. Total payment for energy supply in final demand sector is estimated to be 41.9 trillion JPY. Total CIF price of 20.6 trillion JPY is paid to foreign countries due to imported fossil fuels. This study indicates that introduction of renewable energy and energy supply system transition, in particular of the transportation sector and electricity generation sector, leads to CO₂ reduction and revitalizes local economies. Wind energy, which has a great potential, is important to design a low-carbon society.

Recently Japanese energy security has been unstable, therefore, it is an urgent task to propose an explicit scheme for improving energy security. The purposes of this study are threefold. First one is to establish a specific definition considering significant aspects of the energy security concept. Second one is to evaluate energy security quantitatively based on strategically selected criteria and the last one is to indicate a direction of energy policy towards a future highly secure energy supply system for Japan considering the economic feasibility by applying a multi-objective analysis. As a result, it is realized that the current energy system in Japan is inefficient from both energy supply cost and energy security perspectives, and the system is inferior compared to other developed countries. In order for Japan to improve its energy security level effectively, the expansion of the use of natural gas and renewable energy such as biomass is required.

The purpose of the study is to design a woody biomass energy system and application to coal co-firing, and to evaluate the system considering the three dimensions of energy, economic, and environmental impact. The study targets five types of woody biomass; forest wood residues, forest thinnings, sawmill wood residues, construction wastes and pruned branches of fruit trees. The system contains of collecting of biomass, transporting raw materials, producing wood fuels, transporting wood fuels, and coal co-firing. The study evaluates six cases that differ in wood fuel production location and the type of wood fuel. The results of case study show that the potential of the biomass resource is 37 PJ/year and the availability is 3.6 PJ/year in Tohoku area. The case that pellets produced at the resource generation points has the lowest amount of energy consumption 0.9 PJ/year, wood fuel supply cost 3.2 JPY/MJ and CO₂ emissions 0.66×10³ t-CO₂/year. It is also obtained that the drying process and transportation process have dominant effect on energy consumption and cost.

The passenger amount of air transportation increased up to eight times during past 30 years. Due to the dramatically growth of aviation, CO₂ emissions from aircraft engine doubled during this period. Rapid growth of aviation sector would cause climate change, local air pollution and noise problem. In order to mitigate these environmental impacts of aviation, optimal aircraft operation is necessary. The goal for the research is set to formulate optimization model which can consider these environmental impact and to evaluate the mitigation by applying the model to domestic lines of Japan. This paper describes the airline fleet assignment problem including externalities of environmental impacts. The model explores optimal aircraft type, which minimizes social cost that is the sum of total operating cost and external cost of CO₂ and NO_x emissions. The results show optimal fleet assignment can mitigate environmental impact in some degree. However, it might be almost impossible to achieve the reduction target only by optimal fleet assignment.

It is necessary to improve the sustainability of the industrial sector in developing countries, particularly in the case of energy intensive industries. Energy efficiency improvement and fuel substitution with natural gas and low-CO2 electricity can reduce CO2 and pollutant emissions, energy losses, and improve working conditions. In this research, CO2 emissions reductions achievable with these two measures in non-ferrous metals secondary production and semi-fabrication were estimated; and the barriers that prevent their materialization discussed. A national scale bottom-up static linear programing optimization model was developed to assess the energy resource/end-use device allocation problem in non-ferrous metals secondary production and semi-fabrication; and used to study the case of Colombia, where low-CO2 electricity is available. Besides the base scenario, three alternative scenarios were considered, focusing on different priorities for decision making: (min. cost) minimizing total cost under energy resource and material demand constraints; (low CO2) minimizing CO2 emissions under energy resource and material demand constraints; and (min. CO2) minimizing CO2 emissions under energy resource constraints, except for natural gas and electricity, and material demand constraints. Results indicate that compared with current CO2 emissions of 62.5 kt-CO2/yr, minimum cost system configuration can achieve CO2 emissions as low as 17.7 kt-CO2/yr due to the improvement of energy efficiency; while the minimum CO2 emissions system configuration can achieve CO2 emissions as low as 7.7 kt-CO2/yr, using energy efficient electric devices; which are preferable over regenerative natural gas furnaces for electricity CO2 emission factors lower than 350 t-CO2/GWh. Similarly, pollutant emissions are also expected to decrease. Cost of CO2 avoided is negative in all the alternative scenarios, indicating the existence of ‘no-regret’ CO2 emissions reduction potential. Despite economic and environmental benefits of energy efficiency improvement and fuel substitution, it is considered that barriers such as uncertainty about energy resource price evolution, resource competition between energy use improvement projects and other projects, and lack of knowledge, among others prevent CO2 emissions reduction potential to be realized. Furthermore, it is necessary to improve the characterization of energy use in the industry with updated and detailed information, required to identify more accurately CO2 emissions reduction opportunities.

The mitigation of climate change is thought by many to be a significant environmental concern. In order to mitigate the bulk of carbon emissions from the electricity sector, large market penetration of renewable energy technologies is a key research issue. The goal of the paper is to address the timing of public R&D investment for renewable technologies in the Japanese electricity sector. The model is cast as a dynamic bottom-up energy-system model and numerically optimized, minimizing a total system cost subject to an accumulated carbon emission constraint. Autonomous energy-efficiency improvement and two-factor learning curves describe the technological development process for each energy technology. With the two-factor learning curve, the model shows that the cost of electricity of renewable technologies can be reduced by up to 43% in the year 2100 if there is no constraint on public R&D budget. Renewable energy sources requires substantial R&D support in their initial phase of development; however, the investment pattern would switch to a path of reducing the amount after 2050. The budget of R&D investment is strictly limited; thus, an important policy objective is to design a dynamic investment schedule that will induce sustainable innovations for green technologies.

The paper examines the effects of research and development (R&D) on the capital cost reductions and the introduction of renewable energy technologies, namely solar photovoltaics (PV) and wind technologies. The proposed model in the study deals with the dynamics of technological learning. Functional form is a new kind of three-factor learning curve as a function of the cumulative capacity and the knowledge stock accumulated by public and private R&D expenditures. An econometric analysis is used to identify the influence of the knowledge stock on the capital costs of renewable energy technologies. Moreover, the study clarifies the relationship between the cost reductions and the market penetration. If the expenditures for public and private R&D in 2010 are fixed until 2050, then the model predicts that the capital costs of solar PV systems in 2050 become $1,750 /kW. Sensitivities of the annual R&D growth rate for the technologies are tested. The model also provides important results that the increase by four times of R&D budgets is necessary in order to reach the cost reduction targets by the Japanese government. The proposed methodology herein is helpful for decision makers to forecast how the costs of renewable energy technologies will change, and thereby providing the basis for R&D planning.

The purpose of this research is to design an optimum automotive bioethanol supply chain in Japan. In this research, a mixed integer linear programming (MILP) model provides the optimal design of bioethanol supply chain with the objective of minimizing the cost of supply chain. Furthermore, the model can optimize biomass species, cultivation and traffic volume of biomass, locations and scales of the bioethanol production plants and traffic volume of bioethanol. The transportation cost of feedstock and bioethanol are optimized using Geographic Information System (GIS). Optimized supply chain is evaluated bioethanol production cost, energy profit ratio (EPR) and CO₂ reduction. Tohoku area was selected as a case study. The bioethanol production cost, which uses first generation bioethanol plant is 203 JPY/L, where first and second generation bioethanol plants are installed is 168 JPY/l, where first and second generation bioethanol plants are installed and technological development was considered is 92 JPY/L. EPR of each case are 1.66, 2.49 and 3.40, and CO₂ reduction are 277 kt-C, 288 kt-C and 305 kt-C, respectively. It is necessary to decrease cultivation cost of energy crops and increase bulk density of crop residue to reduce the bioethanol production cost, increase EPR and CO₂ reduction.

Space heating and domestic hot water account for about 50% of residential and commercial sector energy consumption in relatively cold climates. This energy service demand is generally met by fossil fuels causing considerable amount of GHG emissions. In Japan the supply system is mainly constructed of small scale, distributed, building based conversion units being supplied by imported fossil fuels or electricity. In addition to being carbon intensive and almost completely dependent on imported fossil fuel, space heating in residential sector of Japan has been estimated to have energy and exergy efficiency of 99.8% and 4.6%. The low exergy efficiency indicates bad utilization of the available energy content of the supply fuel because of a mismatch between quality levels of the supply fuels and energy service demand. Fuel transition or restructuring of the heat supply system matching the quality level of the energy demand while fulfilling acceptable levels of availability, affordability and environmental impact is therefore of great benefit. District heating system is a flexible heat supply system that can integrate various local heat resources and has proven to supply heat in an effective and cost competitive way. The purpose of this study is to assess the feasibility of a district heating system integrating local, low carbon energy sources, providing space heating and hot water on a small-city scale as a comparison to conventional fossil fuel based heating system. Study area is Hirosaki city located in north of Japan with relatively high fossil fuel prices and high heat loads. An energy analysis of the existing system is conducted, disaggregating the consumption by type of fuel and type of energy service demand. The district heating system is designed in order to match peak load. Steady state thermoeconomic analysis considering peak load conditions is conducted for assessing and comparing the two systems. Performance and exergoeconomic parameters are used to evaluate and compare the systems. Available feasible resources in Hirosaki considered for the district heating system are waste wood, municipal solid waste incineration plant waste heat, sewage sludge and geothermal energy. Together they are able to provide about 17% of the peak load. The insufficiencies of local resources are assumed being supplied by natural gas boiler. Results indicate a considerable reduction in CO2 emissions and the thermoeconomic analysis indicates that low fuel cost and less exergy destruction compensate for the high capital investment cost required for transition to district heating system. Energy efficiency is higher of the reference system and exergy efficiency about the same for both systems at peak load.

Recently, the microalgae that can produce fats and hydrocarbons attracts a lot of attention as means to solve the issue of global warming. The purposes of this study are to design microalgae-based biodiesel fuel (BDF) production system using exhaust gas from thermal power plants and considering regional characteristics, and to analysis potential of the microalgae from the viewpoint of energy balance, CO₂ balance and fuel production cost. The system consists of five components: Culture, harvesting, extraction, transportation, conversion. In addition, the methodology of this study has three processes: Allocating microalgae culture plants and BDF production plants, optimizing transportation using Geographic Information System (GIS) with Network Analyst, and evaluating energy balance and CO₂ reduction of the system. Besides, to minimize BDF production cost, we change the number of BDF production plants and consider trade-off between transportation cost and BDF production plants costs. The result shows that microalgae-based BDF production system has high potential for CO₂ reduction and the possibility to competitive with the fossil fuel cost.

In the production of bioethanol in Asia, developed countries such as Japan have the problems of high cost and a lack of resources, while Southeast Asian countries have substantial biomass production and export potential. The purpose of this study is to optimize the international supply of bioethanol in East Asia. A linear model is developed to estimate costs, energy consumption, and carbon emissions in three processes: cultivation, conversion, and international transport. In order to consider the regional characteristics of producing countries, biomass price, electric power generation, fertilizer usage, agricultural machine usage are incorporated into the model. Optimization based on linear programming is carried out with two objective functions: minimizing cost and minimizing carbon emissions. For each objective function, the amount of supply, economic efficiency, and carbon emissions are quantitatively analyzed in three cases. One is domestic supply case where each country supplies bioethanol to domestic market. Another is Asia supply case where Asian countries supply bioethanol with international supply. The other is Asia-Brazil supply case where Brazil is included in bioethanol supply in Asia. The average supply cost of bioethanol in Asia supply case with the objective function of minimizing cost is a quarter of that in domestic supply case. The carbon emissions reduction increases by international supply. Brazil has more than 50 % share in bioethanol production in both objective functions and contributes to the reduction of carbon emissions.

This paper describes several benefits of the integration of designed optimal municipal solid waste (MSW) utilization system considering energy recovery options and present energy system. A linear programming model has been developed in order to analyse proposed municipal solid waste system, taking into account the 3E's (energy, economic, and environment) aspects. The objective function of the model is to minimize the net cost of the system, under several constraints. A case study in St.Petersburg city, Russia, has been carried out for evaluation of proposed the MSW system. The results show that the introduction of an optimal MSW utilization system has energy, environmental and economic benefits compared with the present system. The proposed integrated system can produce 1,900 GWh/year of heat or 542 GWh/year of electricity in average, which can be supplied to the existing energy system. In addition, the system can reduce the amount of landfilled waste from 89% to 20%, and reduce total system's CO₂ emission by more than 70%.

In this study, 13 types of sewage energy system are evaluated by using inventory analysis. Evaluation indexes are energy balance, greenhouse gas emission, and economic efficiency. The main equipment of those energy systems are three types of incineration, three types of solid fuel, two types of pyrolysis gasification, and five types of digestion. The range of evaluation is from sewage sludge to power generation. Inputs of those energy systems are electricity, city gas, light oil, and wood biomass, and outputs are production of electricity, CO₂ gas, and N₂O gas. The results from the viewpoint of energy balance show that only the systems with gasification furnace produce larger electricity generation than total consumption. The results about the greenhouse gas emission show that the lowest gas emission system is the system with solid fuel produced by drying. N₂O gas emitted by solid fuel is lower than the others. The results about the economic efficiency show that the lowest cost system is the systems with solid fuel because the construction cost that holds most of total cost is much lower than the other systems.

The advantages of coal are the largest reserves among any other fossil fuels, and can be found in many places including some developed countries. Due to the weak energy security of Japan, it is necessary to use coal as an energy source. We have designed the detailed energy model of electricity sector in which we take both energy conversion efficiency and economic aspects into consideration. The Japan model means an energy-economic model focusing on the structure of the energy supply and demand in Japan. Furthermore, the most suitable carbon capture and storage (CCS) system consisting of CO₂ collection, transportation, storages are assumed. This paper examines the introduction of clean coal technologies (CCT's) with CCS into the electricity market in Japan, and explores policy options for the promotion of CCT's combined with CCS. We have analyzed the impacts of carbon tax where each fossil technology, combined with CCS, becomes competitive in possible market. CO₂ mitigation costs for all plants with CCS are detailed and compared.

With nearly 10 % annual economic growth in the past two decades, China has already become the world’s second greatest energy consumer. While coal, accounting for 70 % of energy demand mix and 90 % of thermal electricity power generation by 2005, will continue to be the most important energy resource in China for a long time. How to meet the rapidly growing demand of electricity as well as considering the global need of mitigation of greenhouse gas (GHG), and eliminating other harmful pollutants due to conventional coal combustion such as SO2, NO2 and PM, will be a huge challenge to Chinese government. Integrated coal gasification combined cycle (IGCC) power plant is emerged as an attractive option for both economic development and environment improvement. This research aims to evaluate the penetration of IGCC into China’s electric sector by considering the externalities. A multi-period market equilibrium model (META・Net approach) is applied and an energy model of China is established to forecast changes in the energy system up to the year 2032. Two scenarios are designed: Business as usual (BAU) scenario, Internalizing External Cost (IEC) scenario where external costs of conventional coal power plants are internalized and 15 % of IGCC’s capital cost is subsidized. From the analysis, following results are obtained. IGCC does not penetrate into the market in a large scale in BAU scenario due to its relatively high capital cost. Moreover, results in IEC scenario indicates that by considering the external costs of conventional coal power plants and subsidy, IGCC gains much competitiveness in the electricity sector. Moreover, penetration of IGCC has great effect on emission mitigation. According to the results, it is revealed that IGCC will become an important technology for generating electricity in China and considering the externalities could be a considerable policy option for IGCC’s market penetration.

The purpose of this study is to reveal relations between energy access improvement and poverty alleviation in rural areas of developing countries. Recently, multi dimensional aspects of poverty, for example, economy, health, and education, have been increasingly focused on, and access to modern energy such as LPG and electricity is one possible solution. As a case study, cooking and lighting demand of unelectrified rural areas in Assam state, India, has been analyzed. An energy-economic model has been developed to analyze possibility of energy access improvement through dissemination of a gas stove and electric lighting appliances for cooking and lighting demand, respectively. Moreover, we have estimated changes in the socio-economic conditions, the average Resipirable Suspended Particulate Matter (RSPM) exposure of women and a literacy rate above 6 years old, in the areas. For the cooking demand, the RSPM exposure will be reduced to below 190μg/m3, the WHO criterion of Suspended Particulate Matter (SPM), due to increase in the income level. For the lighting demand, it is shown that complete household electrification will be achieved by the year 2012 based on the model analysis, and the literacy rate in Assam will increase to 74.4% from 63.3%.

In many countries, the concern with municipal solid waste (MSW) has been growing for the past few decades because of changes in lifestyle as well as constraints in waste disposal site. A remarkable increase in the amount of MSW has generated serious environmental impacts caused by pollutions such as fly ash, sludge, and dioxin etc. Waste management policies should be revised and updated in keeping with progresses in environmentally sound technologies. The purpose of the study is to design the optimum NISW management system in Japan. We have derived an optimal system configuration among the various alternative and conventional disposal facilities for waste management by applying a NISW system model. which can consider both the mass flow of the wastes and economic aspects of system operation. The advanced MSW management system which has been proposed can reduce the amount of landfill in FY2010 by approximately 40% in comparison with the data in FY 2000. The system increases the recycling rate in FY2010 by 10% compared to FY2000, and meet the budget allocation for NISW management. In conclusion, the installation of alternative facilities in optimal system configuration has a potential for not only the reduction in the cost of landfill but also the improvement of recycling rate.

This study examines the impact of using hybrid vehicles for passenger transportation on carbon emissions in the Japanese energy system. A partial equilibrium model of the energy sector has been developed to forecast changes in the energy system out to the year 2040. The model can account for changes in technology capacities, fuels, and consumption in response to policy initiatives, such as taxes. We find that hybrid vehicles are more efficient in reducing carbon dioxide emission than conventional vehicles. Hybrid vehicles have a great impact on reducing carbon emissions when BTU taxes are imposed, which in turn has the advantage of encouraging a more diverse set of technologies and fuels.

With regard to the influence of CO and H2 in the coal gasified fuel on the reaction properties of reduction of NH3 and NO,we defined by the experiments using the tubular flow reactor and numerical analysys based on reaction kinetics.Main results are shown below:(1)NH3 decomposition ratio depends only on the concentration of H2.There is no influence by CO,that is,NH3 decomposition ratio decreases exponentially with increasing the concentration of H2.(2)NO decomposition ratio decreases with increasing the concentration of H2.Considering the above mentioned results,the higher the concentration of H2 is,the more the reduction ratios of NH3 and NO increases.In view of these properties,this method has the advantage of fluidized bed gasified fuel for entrained bed gasified fuel with high concentration of H2.

Coal gaseous fuels contain NH₃ which will be converted to NO_x in the gas turbine combustion process, if gas cleaning system is a hot type. Main com-bustible gas components of the coal gaseous fuel are CO and H₂, moreover a small amount of CH4 will be contained. Hydrocarbon such as CH₄ has the effect on NO_x formation from fuel nitrogen such as NH₃. In this study, combustion tests were conducted by using a laboratory scale com-bustor for the study of the influence of the coal gaseous fuel properties on NO_x emis-sion characteristics. Main results are as follows; (1) NH₃ conversion to NO_x increases with increasing CH₄ concentration in coal gaseous low BTU fuel. (2) If coal gaseous fuel containes CH₄, there will be some specific equivalence ratio in the primary combustion zone for the minimum NH3 conversion to NO_x. (3) Its specific equivalence ratio in the primary combustion zone increases with de-creasing CH₄ concentration in coal gaseous fuel.

In order to achieve carbon neutrality by 2050, policies are being promoted to accelerate the shift to renewable energy. The transport sector accounts for around 20% of Japan's total carbon dioxide emissions, and as electrification of the industry progresses, it is attracting a great deal of attention. On the other hand, carbon neutrality cannot be achieved simply by electrification of the automotive powertrain, and a wide range of discussions are needed. The speaker talked about how the automotive powertrain will change in the future from a wide range of perspectives, including renewable energy, internal combustion engines, electric powertrains, fuel LCA, and urban engineering.

This concept defines a wide-area regional energy system including regional cooperation, and proposes a system design method for "whole" optimization that promotes the utilization of renewable energy, drastic reduction of CO2 emissions, and regional economic circulation over a wide area. Through the analysis of factual data and the formulation of guidelines necessary for regional energy system design, we will contribute to the transformation to a decarbonized society and the improvement of resilience of regional energy supply and demand.

Symposium on Environmental Engineering　22　389-392　2012
Publisher: The Japan Society of Mechanical Engineers

More details Close

The goal of this research is to show the synergetic benefits obtainable by integrating energy sectors of society. The usual structure of community energy systems is such that various sectors of the society receive their required energy from mainly centralized facilities (e.g.centralized power plant). There is no interaction between different sectors of society. The goal of this research IS pursued by using a novel methodology R)r designing optimum integrated energy system in which symbiotic cooperation between various energy sectors has been defined. As a result, community's energy demands are met more sustainably. Some of the relative merits of the proposed design compering to present situation are: 37% increase in energy efficiency, 86.5% reduction in net costs, and 17% decrease in amount of CO_2 production per capita.

Publisher: The Japan Society of Mechanical Engineers

More details Close

This study shows an exergetic analysis based on both enthalpy and exergy flow, aiming at the efficient use of biomass energy. Several technologies for heat and power derived from woody biomass can be assessed by means of exergy efficiency, which indicates work potential of energy amount. It also makes clear the lost opportunities to do work in the energy conversion process and offers plenty of room for improvement. The results show significant difference between thermal and exergy efficiencies. The largest exergy loss in biomass power plant is found at the boiler, however the largest enthalpy loss takes place in the steam turbine.

Yoshizaki Haruki, Nakata Toshihiko

Procee[d]ings of Thermal Engineering Conference　2006　163-164　2006/11/23
Publisher: The Japan Society of Mechanical Engineers

More details Close

Coal has some advantages such that coal has the largest reserves among any other fossil fuels, and there is regional uniform distribution of production countries. On the other hand, there are some disadvantages such that the carbon content of coal is larger than that of any other fossil fuels. Technology to use coal for clean and efficiency is demanded. And technical development to contribute to CO_2 reduction is necessary. In this study, the most suitable CCS (Carbon Capture and Storage) system consisting of CO_2 collection, transportation, storages are designed. And introduction and economic aspects of CCT with CCS in electricity sector are investigated.

The steam turbine has been a key component in electrical power generation since the 19th century, as one of the distinctive outcomes of the industrial revolution. In this chapter, we will show the method of cost evaluations and how they change with time. As well as depreciation accounting, diversification of society’s needs leads to better innovation and raises the level of technology. The concept of technological learning is explained to find out how much costs decline with the popularization of technologies. Some generating technologies use similar components and these components learn at the same rate as these units are built. Technological progress mainly depends on three learning sources: learning-by-doing, research and development activity, and knowledge spillover.

New, alternative energy technologies are rapidly becoming affordable, and it is expected that these will be immensely disruptive to our traditional mode of centralised energy generation, transmission, and distribution. Additionally, the severe climate (and other) impacts of many traditional energy generation and utilisation techniques are widely accepted. As stated in the World Energy Outlook of the International Energy Agency (IEA), “the global energy scene is in a state of flux, thrown off balance by falling costs for a range of technologies, led by wind and solar. . . ”. Furthermore, the IEA states that it “. . . expects renewable electricity generation to increase by a further two-fifths by 2021. However, renewable heat and transport are lagging behind, despite good potential. . . ”. For these changes or transitions to be just and sustainable, systemic analyses are required, with an emphasis on optimizing the energy sector to be better integrated with the other sectors of the economy, thereby ensuring the efficiency of future energy value chains. Such systemic analyses utilise concepts, methods and tools such as system dynamics, urban metabolism, industrial ecology, and life cycle analyses, to inform policy- and decision-making. This book is a collection of papers from a Special Issue in the journal Energies, with contributions from researchers across the globe. The book provides insights to scholars on how the concepts, methods and tools of systemic analyses have been utilised in various contexts—from the household and community level, to industrial and utility-scale levels—to enable a transition to sustainable energy systems, with an emphasis on the efficiency and optimisation of future energy value chains.

The aim of this study is to propose a dynamic model for forecasting the changes in the number of batteries recovered from end of life electric vehicles considering different power trains. To achieve a sustainable society, the dependency of the energy on fossil fuels must be overcome. One of the first steps to manage this objective is through the reduction of its direct consumption by the wide-scale adoption of EV (HV/PHV/BEV/FCV). Low cost and stable production of lithium ion batteries (LiB) are expected to be a key element for the electrification of the transportation. For this reason, an efficient cascade use of electric vehicle batteries (EVB) to minimize its raw material supply risk, disposal risk, environmental impact and material cost/consumption in its production process become essential. Additionally, by the promotion of a closed loop life cycle, cost reduction in the end of life batteries treatments can be also expected. However, to grab this opportunity and create a sustainable market, balance between the demand and recoverability of LiB must be clarified to propose reliable second life projects. This study proposes a method based on system dynamics modeling for forecasting the vehicle fleet, sales and end of life vehicles by power train considering data of scrapping rates of vehicles by year of use. Moreover, the supply potential of scrapped batteries from a reverse logistic scheme is analyzed. Here, the Japanese vehicle market is considered as a case study and a timeframe of 2018 to 2050 forecasted. Results indicate that the amount of scrapped EVB will increase 45 times from 2020 to 2050. Moreover, a complete closed loop of them can be expected around 2050 only if the exportation of used electric vehicles is hardly diminished.

To create a biomass energy value chain Invited

The 17th Biomass Premium Evening Seminar　2025/03/03

More details Close

In order to promote the social implementation of biomass energy, we will look back on the history of biomass energy to date, and then consider the business strategies that we should adopt in the future. Biomass has traditionally been used as a material, and energy use has been secondary, and it has continued as a by-product of the domestic forestry industry and waste disposal business. The recent introduction of the FIT system and the transition to a carbon neutral society are changing the significance and value of biomass energy use. I hope that the diverse values of biomass will be redefined by returning to the origins of the energy business, and that a business model will be developed that can absorb the synergistic effects of the multiple layers of value. This will ensure the sustainability of both the global environment and the business itself as a new biomass business that will lead the next generation.

Distribution characteristics of woody biomass potential by municipality based on bottom-up estimation

More details Close

In this study, bottom-up estimation was conducted for each municipality using the product-up method based on the wood biomass potential of each sub-group and forest group from the forest GIS. In order to take forest growth into account, four growth curves were curve-fitted for each tree species, and the curve with the highest coefficient of determination was selected for the estimation method. The input data used were forest GIS data for national forests from the National Land Survey Data and forest GIS data for private forests from prefectural forest registers and forest planning maps. These forest GIS were combined to create a dataset. Missing data in the combined data set was supplemented with forest area data and administrative district data from the National Land Survey Data. Only planted forests were targeted, excluding restricted forests. The number of thinning was fixed at two times, and the harvesting period was assumed to be the year of the maximum desired land value, 60 years, and 80 years, based on the Faustmann equation. The results of these estimations were used to perform a hierarchical clustering analysis of the municipalities in which the target forests were located, using the percentage of tree species as a characteristic quantity. In addition, spatial characteristics were analyzed using the Moran I statistic, a spatial autocorrelation measure, with wood biomass potential per unit forest area as the characteristic quantity. This allowed us to investigate the distribution characteristics of woody biomass potential by municipality.

The shift to 100% renewable energy is beginning to progress in regions amid the global decarbonization movement. European countries such as Denmark were among the first to introduce smart energy systems such as decentralized district heat supply for smart energy use in their regions, and were among the first to make the energy transition to 100% renewable energy. At this international symposium, we will hear from Professor Henrik Lund, a leading international expert on the specifics of Europe's advanced 4th generation district heat supply and smart energy systems, and share information on the frontlines of decarbonization of district energy in the world, as well as on local decarbonization efforts in Japan. The session will also include information sharing and discussion on the frontlines of regional energy decarbonization in the world and efforts to decarbonize regions in Japan.

To accelerate the transition toward zero net carbon emissions, developing the technologies which are already mature enough to be integrated technologically and economically in existing system is essential. Most of the recent studies are focusing on large scale energy systems which require lot of assumptions to be studied (Linear Approach). This paper presents the economical optimization of combined thermal and electrical supply of a city in Hokkaido through utilization of district heating network. A nonlinear approach is used to consider phenomena’s such as combustion efficiencies or effect of scale. Different technologies of combined heat and power are modelled with different properties and fuels such as gas, household wastes and biomass. Other electrical sources are considered as solar, wind or hydraulic power. The optimization objective function is to minimize costs by considering the current costs of energies. With each boiler modelled and sized, optimization results show the interest to use renewable energies especially biomass power, which is widely available in northern Japan, to at the same time reduce the costs and increase the use of renewable energies.

In order to construct an energy system for a decarbonized society, it is necessary to clarify the characteristics of renewable energies such as temporal variation and spatial heterogeneity. Currently, most of the studies on estimating the potential of photovoltaic power generation in Japan are based on annual averages of solar radiation and temperature, or are limited to certain regions. These studies lack temporal and spatial accuracy, and therefore cannot fully grasp the characteristics of renewable energy. Japan has declared its intention to achieve a decarbonized society by 2050. Therefore, research with high temporal and spatial accuracy is expected to contribute to the realization of such a society. In this study, we propose a method for estimating the potential of photovoltaic power generation considering temporal changes and spatial distribution for the entire country of Japan, taking into account the effects of the zenith angle and azimuth angle of the sun at each time and location, based on 1km mesh forecast data of solar radiation every 30 minutes.

This study estimates V2G installation potential, assuming a shift to EVs for private passenger cars. The target regions of this study are a rural area (Iwate Prefecture) where people mainly travel by private car, an urban area (Kanagawa Prefecture) where public transportation is well developed, and regional city (Hiroshima Prefecture) where there is a mixture of rural area and urban areas. In order to clarify the differences in V2G installation potential between regions, we use mobile location data, which provides more accurate information on travel demand than existing surveys such as PT surveys. First, we use mobile location information to estimate the total distance traveled by cars and the number of cars. Next, under the assumption that all vehicles will be replaced by electric vehicles and V2G will be conducted, we estimate the capacity of batteries that can be used for V2G by estimating the number of vehicles traveling, which is estimated using mobile location information, and the number of parked vehicles using car ownership statistics. Finally, we will attempt to use clustering to estimate regional attributes for more accurate estimation of V2G installation potential. Keywords􀀃: Vehicle-to-Grid, Mobile location data, Travel demand,

Nowadays, Japan still occupies the 5th place of the carbon dioxide emissions in the world. Among the emissions, about 40% of the emission is from energy conversion sector and about 20% of the emission is from transportation sector. Therefore, power generation from renewable energy and decarbonation of the transportation sector will be important. In this study, we aim to analysis the demand of travelling cars in order to estimate the energy demand of the transportation sector (mainly vehicles) throughout Japan from the perspective of the temporal and spatial axes. Using the population information obtained from cell phones located in each base station in different areas or GPS, we analysis the flow trend of population, find how to estimate the demand of travelling cars from the demand of floating population. We focus on three areas (Iwate Prefecture, Yokohama City and Hiroshima Prefecture) of Japan and try to analysis the demand of travelling cars of the whole country by floating population of these areas.

In this study, we constructed an agent model by simulating a power system in Japan considering an autonomous decentralized system with a simple graph structure. In this model, The Gale-Shapley algorithm was applied to the agent matching method and electricity demand and supply data for 47 prefectures in 2019 was used. Then, we evaluated the effect of equalization of supply and demand between regions, analyzed the power flow between regions, and displayed effective network structure considering the spatiotemporal dispersion of renewable energy potential. When agents are isolated from each other, the power shortage time of agents in the Tokyo metropolitan area and Osaka exceed half of the analysis target period (8760 hours). In contrast, with interregional power interchange, most of the power shortage hours can be almost eliminated in all prefectures, reducing 2169 hours to 25 hours per agent. The simulation result shows that there are regional differences in the destination and amount of flow in interconnection, and that geographical arrangement of supply and demand areas has a great influence on power interchanging behavior of agents.

Energy system models with higher spatio-temporal resolution are effective for designing highly renewable energy systems and for the development of energy policies. Existing energy system models pursue macro-optimality based on system cost minimization. However, the profitability of business sector is neglected. In other words, from the perspective of business feasibility, they could be infeasible. In this study, we focus on P2G/P2L as balancing technology, and design and analyze the energy system with and without considering its profitability. First, a break-even analysis is conducted, and it is verified that the break-even can be achieved at the reference cost in 2030. Next, we developed an energy system model with profitability constraints considering the capacity factor’s lower bound. At this time, a method to express the profitability constraint as a capacity factor lower bound constraint was proposed. Finally, future energy systems with and without profitability constraints were designed. It was found that the system cost increased by 5% in the case with the profitability constraint compared to the case without profitability constraint. The energy system designed without the P2G/P2L profitability constraint was not feasible because the hydrogen production could not achieve break-even. These results indicate the importance of profitability constraints in energy system models. Keywords: Energy system model, Feasibility study, Sector-coupling, P2G, P2L

Energy is the basis on which society and life are built. Since the early modern era, as the use of fossil fuels has progressed and the electric power grid has been developed, the geographical limitations of energy sources have been less of a concern, but recent energy-related issues, such as the call for carbon neutrality, show that this has been a peculiarity limited to the last two centuries. However, recent energy-related issues, such as the call for carbon neutrality, reveal that this has been a unique phenomenon limited to the last two centuries. In the end, it is hard to say whether the future of energy will develop into a more global network or return to the original local production for local consumption. In this forum, we would like to take a bird's eye view of the issues and problems related to energy from the perspective of integrating society and technology, using the relationship between energy and society as a starting point, together with the participants.

In order to promote the introduction of renewable energies in the region for the construction of a decarbonized society, it is important to understand the amount of woody biomass that exists and the amount that can be used. However, the amount of woody biomass available for use by region has not been estimated for the whole country. In this study, we estimated the amount of woody biomass available and the amount of woody biomass that can be used in municipalities across Japan by using the proportional distribution method by tree species based on the statistical data of prefectures, and compared the amount of woody biomass available by changing the conditions of forest road networks.

Detailed energy demand data allows for more accurate and complex energy systems design including concepts such as districtheating or peer to peer energy sharing, but the availability of smart meters data faces privacy problems. While individual smart metersdata can be exploited with machine learning algorithms such as clustering, geographically aggregated data makes difficult thepartitioning of energy demand profiles. The present study suggests the use of independent component analysis to extract demandprofiles from smart meters meshed data. Based on data from Yokohama city in Japan, we try to identify the optimal number of demandpatterns to look for, interpret them, and analyze their geographical repartition.

For an efficient integration of wind and solar resources toward sustainable energy systems, it is crucial to consider their fluctuations in space and time. Current spatial wind potential estimations in Japan are limited to the annual average of wind speed. In this study, we evaluate the spatial and temporal evolution of both onshore and offshore wind energy potential in Japan based on 5 km mesh and 1-hour sampling weather forecast data. We then demonstrate the benefits of cross-border sharing on the power output stability and identify important sites having high average potential and low average correlation with other sites for the temporal smoothing of power output.

132nd Annual JFS Meeting　2021/03/19

More details Close

This study aims to estimate the available wood biomass resources in 1,741 municipalities across Japan. The “Renewable Energy Information Provision System (REPOS)” published by the Ministry of the Environment in June 2020 provides information on renewable energy potential by region, but the resources covered are limited to solar, wind, and small-scale hydro power, and do not include wood biomass.Additionally, while some municipalities have independently estimated their available woody biomass resources, few have done so using a standardized methodology across all municipalities nationwide.Therefore, this study attempts to estimate the available woody biomass quantities by municipality using a top-down approach based on publicly available data on the current status of forest resources, such as age-class-specific accumulation and standing timber volume. The estimation procedure involves first estimating the woody biomass resources by prefecture based on publicly available data from the Forestry Agency. Next, the woody biomass resources by municipality are obtained using a proportional allocation method based on forest area.Finally, the area available for timber harvesting is estimated based on the length of forest roads in each municipality, and the available woody biomass is estimated for each municipality. The forest resources targeted in this study include privately owned and publicly owned forests, artificial forests, and coniferous and broadleaf trees.

In the context of rising concerns on climate change, e orts are made to improve our energy systems with the target of a carbon-neutral society by 2050. Energy systems are complex systems yet most modeling approaches do not consider their core aspects described by complexity science so far. These aspects can be grouped into Adaptation, Nonlinearity, Self-organization, and Network, which are interrelated and without which one cannot explain energy systems complex dynamics. The present study suggests the use of machine learning models to capture energy systems complexity. Some studies have already implemented machine learning for cluster analysis or forecasting purposes, but the potential of such techniques is still far from being fully exploited. We remind some understanding of complex systems then explain how machine learning models can complement or surpass current models as well as their limitations. Concrete examples are given for real applications.

The purpose of this research is clarify the role of each municipality for the sustainable and decarbonized society and provide the evidence for policy makers who tackles making effective energy policy that focused on the region. As a background, Japanese municipalities has been required to make regional energy plan but over the 70% municipalities has not done the drawing up. We refer the governmental survey and presume the course of this problem is the individual region doesn’t have enough renewable energy resources or energy demand of financial capability. As a solution for the problem, we propose generating cross-border area that some regions shares these resources and demand each other and improve their energy self- sufficiency. For solving the problem, we developed spatial clustering method that applied cluster analysis algorithm to the graph partitioning. As a result of some case study, cross-border area shows higher performance nearly prefecture than individual cities in energy self-sufficiency perspective. Designed Asahikawa cross-border has energy circular structure that Asahikawa city as a central large demand region obtains energy resources from neighbors including Horokanai town. Energy self- sufficiency of the area is 143%.

This research aims to analyze the introduction impact of sector coupling toward decarbonized energy system in Tohoku area, Japan. First, we have developed optimization model to design sector-coupled energy system. Then, several scenarios regarding energy consumption in demand have been input and their performances have been evaluated. As a result, TPES decrease in all scenarios, but the annual system costs increase from 80% to 140% compared to the current level. Half of this costs are accounted for by power generation, which exceeds the current system cost. Since vehicle-to-grid and power-to-heat contribute to improving capacity factor of the electrolyzer in addition to the balancing electrical grid, the introduction of vehicle-to-grid and district heating lead to the reduction of annual system costs. Furthermore, reinforcement of transmission lines reduces annual system costs, but the effect is weaker as more sectors are coupled. In sector-coupled energy systems, it is difficult to optimize without cooperation of various players, so the design of market mechanisms is important for social implementation.

While district heating systems (DHS) are widely introduced in Europe, heating systems in Japan are still mostly individual. DHS allow to utilize excess heat. The purpose of this study is to design and evaluate potential DHS using excess heat and power generated by renewable energy in Izumi Park Town. First, heat demand in residential and commercial sectors is estimated from public data, and a heat demand map is created using GIS. Next, a heat pipeline is designed based on the map, and the system is evaluated in terms of energy and environment, considering the case of utilizing excess heat or the use of power generated by renewable energy. As a result, it was found that the designed DHS using excess heat achieves an energy efficiency of 93%, and allow to reduce CO2 emissions by 75% from the current level. Moreover, by using power generated by renewable energy, the energy efficiency was improved to 92.7% and CO2 emissions from heat supply were reduced to zero. It was also found that it satisfies European design standards for heat density and linear heat density. From this result, it was found that DHS can greatly contribute to decarbonization by using exhaust heat and surplus power.

roceedings of the Conference on 15th Biomass Science　2019/12/12

More details Close

Energy conversion technology of woody biomass (WB) has attracted attention because of carbon neutral energy. On the other hand, the energy use of WB is not advanced sufficiently since WB power generation costs are higher than grid power generation costs. One of the reasons for high cost of WB power generation are that the WB fuel costs account for more than 50% of the total power generation costs, which is essential to reduce WB production costs in order to expand the use of WB. Costs, life cycle assessment, and technological performance and improvement of WB use have been discussed previously. However, those studies tend to be limited to present technologies and specific areas. Moreover, they have not discussed the impacts of technological improvements and/or introduced technologies to the WB power generation costs. In this study, we focus on the WB production cost, and clarify the correlation of each factor between processes and the impact of each element improvement on power generation costs. We design a WB production process, calculate its cost by a detailed bottom-up approach, and propose technological scenarios to show innovation pathways to utilize WB effectively. We find that it is important to improve the chipping cost and the labor efficiency of timbering, and thus it is suggested that the WB power generation cost can achieve 25 JPY/kWh which is a target cost in this study.

In this study, we have designed a wastewater heat energy utilization system by spatial analysis of both wastewater heat utilization potential and heat demand using GIS. The system consists of a heat exchanger, a heat pump, and a heat consumer. The potential is estimated by multiplying wastewater flow rate to specific heat and temperature difference. Heat demand is estimated by multiplying unit of heat demand to total floor area or number of households. As a result of case study in Hirosaki city, Aomori prefecture, wastewater heat utilization potential of 0.17 PJ/year corresponds to 0.7 % of primary energy supply in the city. In addition, it is found that introducing medical facilities into the system as a heat resources, the primary energy supply and the CO2 emission can be reduced by 38 % and 50 %, respectively.

This study aims to design the wood energy system based on the local energy demand distribution. For zero CO₂ emission, not only wood biomass but also other renewable energy such as solar and wind are considered. The monthly and daily energy demands of residential and commercial sectors are evaluated using an annual demand. The renewable energy potential is also evaluated using the local characteristics. As results in Fukushima prefecture, the electricity demand 33.3 PJ and the heat demand 38.5 PJ are obtained. Further, the wood biomass potential 33.8 PJ is also obtained. The wood biomass is utilized to the heat supply because the electricity demand is mainly covered by the solar and wind energy.

The purpose of this study is to evaluate a mechanized wood harvesting system. The system consists of felling, skidding, processing and forwarding. In gentle slope areas, the system is designed by using vehicle-based forestry machines (Feller buncher, Skidder, Processor and Forwarder). We define the scale of land as 250-m mesh (6.25 ha) and locate forestry road networks and timber yards. As a result of using two feller bunchers, two skidders, two processors and two forwarders, it became clear that the productivity is about 28 m³/man-day. Based on this result, energy consumption, CO₂ emissions and total cost will be clarified.

In this study, we design a sustainable logistics system of forest biomass considering forest biomass supply chain linking from forests to power plants. The system consists of four depots, forests, natural drying sites, pellet plant and power plants, linked by truck transport. We calculate transportation amounts and storage on a day-to-day basis for a year with the linear programming using spatial information of amounts of available forest biomass, demands of power plants, and locations of depots. From this analysis, we reveal robust transportation network, supply cost, inventory turnover rate, lead time, energy consumption and CO₂ emission of the system. Using five indexes, energy consumption, CO₂ emission, cost, inventory turnover rate, and transport efficiency, we evaluate the performance of the system.

This paper shows the economic impact of introducing offshore wind power by I-O analysis. It is important to build consensus between wind power operator and fishery industries because fishery has an important role for local industries. Therefore, this paper shows the economic impact caused from withdrawal of fishery and installation offish-farming. The target area of this research is focused on Japan, Ibaraki prefecture and Iwate prefecture. The final demand occurring from the whole project is assumed and the regional final demand is calculated. The economic ripple effect to other industries is evaluated using I-O table. The results shows that the construction and operation of offshore wind farm produces a lot of economic effect, and the withdrawal of fishery cause the economic loss in local area. In order to introduce more renewable energy, cooperative systems with other industries must be designed.

Estimating technological progress of emerging technologies such as renewable energy technologies is essential for designing sustainable energy systems and drawing energy policies. Learning curve is a quantitative estimating method for describing the cost decline rate of technologies caused by technological progress and learning. The purpose of this study is to estimate learning curve and learning rate (LR) of capital cost in wind power generation in Japan. As a result, 11% of learning rate was obtained from the analysis using capital cost data, though it included some uncertainty caused by the lack of cost data. Moreover, the difference in correlation was analyzed when classified by the capacity or the country of wind turbine manufacturers. The LR obtained in the study was higher than the one in Germany and Denmark. The reasons behind cost reduction were discussed in the latter section.

Agricultural meteorological disasters due to droughts and heat waves accelerated by future climate change may soar food prices and induce global political and economic turmoil. This study developed the economic model linked with crop and energy models to predict crop yields as well as food prices in each country all over the world. By using this method, the prediction accuracy of food price changes based on the results of seasonal forecasts at 3 or 6 months ahead by the global climate model was quantified, and limits of the food price prediction were evaluated. As a result, food price changes in countries around the world 3 to 6 months ahead can be predicted with an accuracy of about 20%. Although the accuracy decreases as the period increases, the accuracy decrease due to the 3 month extension is less than 10%. The accuracy can be further improved by considering the oil price changes. Based on these results, this study proposed some implications for agricultural and economic policies.

Category: Development and demonstration of a design method for regional centers for sustainable resource and energy use

Institution: Tohoku University

2017/04 - 2020/03

More details Close

In this study, we developed a design method for regional centers as a design tool to realize a low-carbon regional energy system using renewable energy. First, we estimated the energy demand and renewable energy installation potential of the target region based on statistical data and geographic information. Next, we developed a regional energy and economic model that takes into account the market equilibrium of renewable energy resources inside and outside the region, and predicted the transition of energy supply structure in the region by dynamic simulation. As a result, it was clarified that it is desirable from the viewpoint of economic rationality to introduce energy resources from inside and outside the region in an appropriate ratio, and it was suggested that it is important to consider resources from inside and outside the region from a bird's eye view when designing a regional energy system. In addition, we analyzed the energy supply and demand characteristics of 1,741 cities, wards, towns, and villages in Japan, and designed a trial wide-area zone for integrating renewable energy among the regions. As a result of analyzing the energy system of the designed wide-area region, it was confirmed that a wide-area region could be formed nationwide, mainly in the Tohoku region. In addition, it was found that the formation of a wide-area zone can be expected to have a certain effect in solving regional energy policy issues such as inconsistency in energy supply and demand and lack of financial resources.

The regional energy systems have been designed in this study. First, the energy consumption and supply on a prefectural scale are analyzed and visualize. The regional energy demand distribution is compared with the potential of renewable energy. This study indicates that development of local energy systems, especially local heat supply system, is important to introduce local renewable energy, and introduction of renewable energy leads to more balanced regional energy demand-supply distribution. Second, the frameworks that evaluate energy security and energy resilience quantitatively to design a sustainable energy system are established. Further, a two- factor learning curve is employed, and the impact of the learning effect on the dynamic diffusion of major renewable technologies is quantified. Finally, the optimum regional energy system for low carbon and higher resilience is designed. The designed systems are suggested to the municipal government as smart energy plan.

The purpose of this study is to design the smart community system based on energy flow and energy map in Tohoku area that was damaged by the Great East Japan Earthquake. Energy flow shows the quantities of primary energy supply of each fuel, energy conversion efficiencies of each technology, and energy consumptions of each sector. Energy map consists of the layers such as resource distribution, road network, and demand distribution. As case studies, the district heating systems (DHS) using local resources in Mogami town, Miyako city, Ofunato city, and Hirosaki city are designed based on the energy map of heat demand. The heat transportation network and the plant location are optimized with cost minimization by solving mixed integer linear programming. As a result, DHS is installed in central area of each city even if the heat density is less than 4.2TJ/ha that is conventional baseline of DHS in Japan. Obtained results are cited in the reports of smart community framework in each city.

The research studies the following subjects: 1. Biomass resources and available conversion technologies in the target area, 2. Development of an energy-economic model considering the economics and operations of rural energy system, 3. Design of integrated energy systems for rural area by the analysis of climate conditions, demand changes deriving energy-economic model, 4. Building the way of designing energy systems for the use of biomass resources as a fuel in rural area. 5. Clarify the target of biomass conversion technologies for practical use of biomass resources. First we have developed the application of GIS database for use in bio-fuel based transportation systems. The amount of bio crops in different area is qualified, including soil condition, the type of agricultural crops, and local climate conditions. Then, an energy market where electricity and heat are supplied and distributed based on the market equilibrium is designed. Different conversion technologies are introduced according to market competitiveness such as capital costs and O&M costs. The study also considers the scale of economy leading an cost reduction, transportation costs from biomass farms to conversion plants, revenues by selling electricity from biomass power to utilities. The cost minimum configuration of the energy system is finally derived through the research. The important finding is an integrated approach for biomass utilization, because the single approach does not work well having different dimensions. Biomass itself has several dimensions such as carbon neutral emissions, internalization of externality of wastes, and market competitiveness. The study has shown the idea of integrating different dimensions in order to integrate the rural energy system using biomass as a fuel.

二酸化炭素(CO_2)排出量増加に伴う地球環境問題と、原子力プラントに付随するリスクをどのように勘案するかは未だ不明確である。さらに、近年の電気事業の自由化に伴って、発電コスト等の経済性を一層重視する傾向が強まってきた。市場競争力と地球環境の両方に適うエネルギー技術・政策が、国家のエネルギーセキュリティにとってきわめて重要になっている。本研究では、エネルギー・経済モデルを用いて原子力発電のフェイズアウト(段階的廃止)を想定した解析を行い、わが国のエネルギーシステムに及ぼす影響を検討した。その結果、原子力フェイズアウトによる主な影響は、発電部門における石炭とガスの消費であることが明らかになった。原子力発電は廃止されるに伴って、石炭とガスを燃料とする発電が増加し、結果としてCO_2排出量も増大する。解析に基づいて下記の結論が得られた。・原子力フェイズアウトとは、原子力エネルギーから石炭やガスなどの化石燃料への移行を促し、結果として発電部門からのCO_2排出量を増加させる。・ CO_2排出量を削減するためには、炭素含有量の低い燃料への移行とエネルギー消費量の減少が必要となる。再生可能エネルギーのような新たなエネルギー変換技術の到来は、エネルギー消費量の削減に効果が期待できる。・各ケースを比較して、需要サイドヘの費用負担は概ね同等であった。CO_2排出量の減少にはエネルギー消費量の低下が伴い、高効率機器への転換が進んだことも一因となっている。

Under the current assessment system, the project owner has to draw up a certain amount of plans before they can be submitted. Residents have the impression that there is no point in saying anything. If they change the plan, they may be confronted with the possibility that it was a lousy plan. I think it is essential to set up a forum where people can discuss in advance what kind of project would allow for a soft landing and what kind of advantages it would have. Professor Nakata believes that this case is a manifestation of the problems with Japan's environmental assessment process.
