Competitiveness of CO2 capture from an industrial solid oxide fuel cell combined heat and power system in the early stage of market introduction

Economic results showed that for above 40-50 $ t−1 CO2 price, SOFC-CHP systems were more economical when equipped with CO2 capture. CO2 capture also enabled SOFC-CHP to compete with GT-CHP at higher cell stack production costs. At zero CO2 price, cell stack production cost had to be as low as 140 kW−1 for SOFC-CHP to outperform GT-CHP. At 100 $ t−1 CO2 price, the cell stack production cost requirement raised to 350 $ kW−1. With CO2 capture, SOFC-CHP still outperformed GT-CHP at a significantly higher cell stack production cost above 900 $ kW−1.
