Abstract
This paper describes on a comprehensive economic analysis concerning biomass gasification systems. In Japan, promoting biomass energy systems in domestic area comes to be expected recently. However, there are some problems in achieving this project. The costs for plant building are very expensive comparing with conventional ones. Accordingly, the unit costs of electricity increase up to as high as other environmental energy systems. In this paper, biomass energy systems using woody biomass are proposed from the viewpoints of successful environmental business. The biomass integrated gasification combined cycle (BIGCC) plant by Independent Power Producer and biomass gasification co-generation (BGCGS) plant in the sawmill or the asphalt-concrete production factory will have opportunities to be implemented in the near future. Our analysis concludes that the systems proposed in this paper provide the following outcomes with subsidies: (1) the generating cost in BIGCC becomes from 15.1 to 36.6 yen/kWh, (2) the gen rating cost in BGCGS becomes from 2.6 to 32.2 yen/kWh, (3) the cost reduction of products in BGCGS in asphalt factory comes to about 60 million yen per year.
