Evaluation of carbon dioxide emission reduction in an energy cycle based on biomass gasification and molten carbonate fuel cell; Exergoeconomic and environmental analysis

Abstract A competitive advantage for the molten carbonate fuel cell (MCFC)-driven energy processes is their versatility. On other hand, since MCFC consumes carbon dioxide, it can reduce amount of dioxide emissions compared to cells. Accordingly, current paper develops and evaluates thermodynamic, exergoeconomic environmental analysis a new hybrid process (HEP) based on reformer stack biomass gasification process. homogeneous ignition engine (HIE) heat recovery system are two main units embedded in developed HEP. In cycle, HIE produce electric energy, which required supplied through obtained syngas from anode off-gas, respectively. The also leads establishment thermal balance cycle by recovering energies HIE. aim present work develop multi-aspect evaluation proposed toward fruitful implementation feasibility analysis. outcomes indicated that, rates electrical powers planned HEP were equal nearly 1112 kW 367 kW, Further, calculated efficiencies electric, gross power total terms 51.5%, 55.7%, 69.9%, had 48% less an petroleum-fired plant, 15.8% natural gas-fired approximately 63% lower coal-fired plant.
