Outline of Final Research Achievements |
By comparing the balance between heat input and waste heat and the temperature range of waste heat from the developed process flow diagram of the biomass power plant, the amount of waste heat relative to heat input and the temperature range are reasonable for power plants using biomass as well as for other general industries. A database of industries using biomass was created to estimate the amount of biomass-derived waste heat and its temperature range, and the amount of heat demand and its temperature range in basic municipalities were estimated as well. The waste heat recovery potential was successfully calculated based on the design results of numerical analysis of thermochemical energy storage and transport system using a water vapor adsorption/desorption cycle of zeolite.

Academic Significance and Societal Importance of the Research Achievements |
地域の熱の脱炭素に貢献する,バイオマスの未利用熱を回生する熱融通システムのポテンシャルをトップダウン手法とボトムアップ手法の組み合わせにより定量化した. 国や都道府県単位では解像度が粗かった熱の検討を,基礎自治体単位で評価することで,熱融通技術の適用可能性が高い基礎自治体を示すことができ,実装に向けた検討をスピードアップすることが可能となる.
