Abstract

The coupling of renewable energy sources and innovative power generation technologies is of topical interest to meet demands for increased power generation and cleaner environmental performance. Accordingly, biomass is receiving considerable attention as a partial substitute for fossil fuels, as it is more environmentally friendly and provides a profitable way of disposing of waste. In addition, fuel cells are perceived as most promising electrical power generation systems. Today, many plants combining these two concepts are under study; they differ in terms of biomass type and/or power plant configuration. Even if the general feasibility of such applications has been demonstrated, there are still many associated problems to be resolved. This study examines a plant configuration based on a molten carbonate fuel cell (MCFC) and a recirculated fluidized-bed reactor which has been applied to the thermal conversion of many types of biomass. Process analysis is conducted by simulating the entire plant using a commercial code. In particular, an energy assessment is studied by taking account of the energy requirements of auxiliary equipment and the possibility of utilizing the exhaust gases for cogeneration.
