The purpose of the research is to design a woody biomass supply system for 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. The system contains of harvest of biomass, harvested wood transportation, production of woody biomass fuels, wood biomass fuels transportation, and energy conversion. The results show that pellets produced at the pre-treatment plant where there is 25km from demand point have the highest amount of energy on investment and the lowest amount of CO_2 reduction costs.

Independent and distributed power supply system is desired when the disaster will be happened. We have examined thermoelectric power generation by biomass and thermal wastewater. The cooling method of thermoelectric device becomes important to generate electricity by temperature difference. The experimental study was performed related to the thermoelectric power generation utilizing the heat of wood burning stove and thermal wastewater.

This paper proposes the optimal planning of incineration plants considering the unused biomass fuel. When improve power generation efficiency in areas where quantities of refuse are small, it is essential to utilize resources like woody biomass which generates high amount of heat. Among them, unused wood is attracting attention. Though it has a latent availability as a resource, its collection cost is high, so it had been left in the woods without being carried out, but there is a possibility that implementation of FIT may make it possible to earn electric power selling revenue to complement the collection cost. This study verifies the effect of the introduction of unused biomass fuel. As a result, there is no merit in the present situation, the benefits will come if the available amount increases.
