Negative emission power plants: Techno-economic analysis of a biomass-based integrated gasification solid oxide fuel cell/gas turbine system for power, heat, and biochar co-production—part 2

In our previous work (Part I), we evaluated the thermodynamic models of biomass-fed integrated gasification solid oxide fuel cell system with a carbon capture and storage (BIGFC/CCS) unit. this II), techno-economic analysis proposed negative emission power plants is carried out. Levelized cost electricity, net present value (NPV), payback period, internal rate return (IRR), levelized (LCNC) are key economic parameters evaluated. The results series sensitivity show impact agents stepwise increase in biochar co-production on performance system. total overnight estimated to be 6197 $/kW 5567 for air steam-oxygen BIGFC/CCS systems, respectively. Steam-oxygen found more economically beneficial than one all cases studied. Economically viable identified ascertain influence capital cost, operating biomass plant capacity factor, tax. Moreover, effect credit scenario indicators also reported. that most effective from case reported an NPV 3542 M$, IRR 24.2%, period 3.3 years, LCNC -322.5$/t CO 2 . Compiling Part I II shows it easier achieve using These expected helpful stakeholders identifying appealing emissions projects near long-term future investments.
