Design of Energy System Introducing Biomass Resources for a Rural Area
Kazuo KUBO, Toshihiko NAKATA
The study focuses on the design of renewable energy systems introducing biomass resources for a rural area in Japan. In an energy-economic model, woody biomass and animal manure (livestock and poultry manure) have been introduced to supply stable power, combining with wind and PV etc. Intermittency of climate conditions and the changes in demand of electricity are carefully considered to examine cost effec-tive systems for the area. As a result, we have found that gasification of woody biomass can supply electric-ity at a reasonable cost, and the biogasification of animal manure becomes cost effective provided inverse onerous contract of the waste is available. The renewable energy system reduces the carbon emissions by 65%, and reduces the annual cost of the entire system by 15%.
