Comparison of various CO2 capture strategies for five optimized fuel-to-power systems based on solid oxide fuel cells: Technical, economic, and environmental analyses - ScienceDirect

By utilizing various oxygen generation methods (e.g., cryogenic distillation, membrane-based separation, etc.) and hydrogen production techniques (e.g., reforming, membrane-assisted separation, etc.) alongside a solid oxide fuel cell (SOFC), it is feasible to design diverse power plants with nearly zero CO2 emissions. Despite the growing interest in solid oxide fuel cell (SOFC)-based systems for clean and efficient power generation, limited studies have comprehensively compared different methane reforming techniques integrated with SOFCs from energy, economic, and CO2 emissions perspectives. This study presents a comprehensive technical, economic, and environmental assessment of six optimized MCFC-based power plant configurations, each integrated with different CO2 capture technologies: calcium looping (CaL), cryogenic CO2 capture (CCC), proton exchange membrane electrolyzer-based CO2 capture (PECC), oxygen membrane-based CO2 capture (OMCC), and vanadium chlorine-based CO2 capture (VCC). The integration of Solid Oxide Fuel Cells (SOFC) with Carbon Capture technologies has shown promising potential for sustainable energy production and emissions reduction.

For the German situation this approach arrives at the following conclusions: - CCS technologies emit per kWh more than generallyassumed in clean-coal concepts (total CO2 reduction by 72–90% and total greenhouse gas reduction by 65–79%) and much more if compared with renewable electricity – nevertheless, CCS could lead to a significant absolute reduction of GHG-emissions within the electricity supply system; - depending on the growth rates and the market development, renewables could develop faster and could be in the long term cheaper than CCS based plants; - especially, in Germany, CCS as a climate protection option is phasing a specific problem as an huge amount of fossil power plants has to be substituted in the next 15 years where CCS technologies might be not yet available.
