An instance growing of greenhouse gas emissions particularly CO_2 has been a global environmental issue that demands distinctive and practical actions to overcome. Tracking from the grass root of the ...great source of CO_2 emission, burning of fossil fuel can be indicted as the most influential contributor of anthropogenic activity. Thus, in addition to the reason of energy scarcity, it is necessary to massively shift the fossil fuel to renewable energy that introduces cleaner and environmentally benign energy resources. In this study, integration of biomass gasification (BG) and solid oxide fuel cell (SOFC) is applied to measure how much CO_2 emission can be reduced. However, the approach is not merely relying on renewability. It is correspondingly considered to abandon burning/combustion either partially or completely by utilization of the waste heat recovered from exhaust gas as well as excess heat from exothermic reaction to generate steam or external heat supply. In-situ utilization of CO_2 is also investigated in the systems. CO_2 emission is calculated by thermodynamic properties of each chemical compound that involves the material balance, energy balance, and chemical equilibrium. Three scenarios of BG-SOFC integration system are presented in this study. Among those 3 scenarios, lowest CO_2 emission with high electric power output and char-free of gasification products is obtained in the scenario 3.続きを見る
