Outline of Final Research Achievements

Conducted an inventory survey on the procurement of wood for fuel including forest residue from forestry enterprises, and estimated the greenhouse gas (GHG) emissions of biomass power generation using it using Life Cycle Assessment (LCA). did. As a result, it was 0.23 to 0.38 kg-CO2 / kWh, and the reduction rate from commercial power (derived from fossil fuels, etc.) in the location area was 30.8 to 60.3%. When comparing with the GHG emissions of commercial power generation, a sensitivity analysis was conducted with the transmission end power generation efficiency set to 10% or 30%, and it was estimated that the GHG emissions were 41.8 to 150.0% compared to commercial power generation.

Academic Significance and Societal Importance of the Research Achievements

本研究は、林地残材を含む発電用原料として利用する場合のGHG排出量について、LCAを用いて定量的に明らかにし、化石燃料等を由来とした電力のGHG排出量と比較したものである。日本国内における林地残材を含む木質バイオマスの収集と発電利用のLCAについて、意欲的に分析したものであり、これらは、国による政策検討や計画目標の到達に資するものとして活用できる可能性がある。本研究成果により国産燃料材利用実績をさらに押し上げ、地球温暖化防止の観点から木質バイオマス発電の推進が期待される。
