Supply Chain Analysis for Determining the Requirements for Continuous Woody Biomass Energy Utilization Systems: Comparison of the Actual Management Conditions in Japan

抄録

In Japan, the number of newly constructed woody biomass power plants are expected to increase with the introduction of the Feed in Tariff mechanism. However, many woody biomass energy plants, including heat supply systems, face difficulties because of issues such as high fuel costs and find it difficult to maintaining a stable supply. This study aims to reveal the requirements for continuous business regarding woody biomass energy, focusing on four factors: wood supply, fuel manufacturing, energy supply, and energy demand. Specifically, we selected multiple Japanese cases that focus on the types of woody fuels such as cordwood, wood chips, and wood pellets, conducted semi-structured interviews, and compared and examined how their supply chains successfully developed. We found that integral cooperation among the four factors was essential, and support regarding each factor, economic viability, as well as balanced supply and demand for wood were necessary for ensuring continuous woody biomass energy utilization systems.
