Combined biomass gasification, SOFC, IC engine, and waste heat recovery system for power and heat generation: Energy, exergy, exergoeconomic, environmental (4E) evaluations

A novel hybrid system using biomass as fuel for both power and heat generation, which consists of biomass gasification unit, solid oxide fuel cell, homogeneous charge compression ignition engine and waste heat recovery unit, is proposed in this work. Based on the modeling, the system is comprehensively evaluated by multiple approaches including energy, exergy, exergoeconomic and environmental analyses. It is found that the overall energy...
