This study focuses on the evaluation of biogas as main source of energy for a direct-biogas SOFC-MGT hydrid CHP system. A sensitivity analysis was conducted under various operating conditions to investigate the influence of the key operating parameters of the hybrid CHP system with a consideration of the operational constraints. The key parameters in this study are SOFC reforming agents and SOFC fuel utilization factor (U_f). The study also presents guidelines to achieve the optimum operating conditions of the hybrid CHP system, e.g. the overall system efficiency, SOFC efficiency, the termal energy to electic power raito (TER) and the electric power of MGT to SOFC (P_MGT/P_SOFC), based on the desired heat and power outcomes.
