—Biomass gasification has received considerable attention as a partial substitute for fossil fuels power generation. In addition, the energy efficiency of biomass gasification can be greatly enhanced when operated with highly efficient power generation systems, such as solid oxide fuel cell (SOFC). The combined cycle is called integrated biomass gasification fuel cell (BGFC) system. In this research, rice straw is used as raw material for power generation as it is available in large amounts in Thailand. The objectives are finding the optimal operating conditions in order to make highest power efficiency and evaluating environmental impact of BGFC system. Aspen plus is used to perform a simulation in this study. In addition, Life cycle assessment (LCA) method is applied using global warming, acidification and eutrophication potentials. The results show that BGFC operated in the optimal conditions can generate 651.35 kW of net power output and 59.17% of efficiency. Moreover, the impact of global warming, acidification and eutrophication is 0.4077 kgCO2
