摘要: Abstract Carbon capture and storage is crucial to decarbonising the power sector, as no other technology can significantly reduce emissions from fossil fuel generation systems. Yet, mature CO2 technologies result in net efficiency penalties of at least 7% points. Emerging technologies, such calcium looping combustion, penalty 2.4% Further reductions be achieved by replacing conventional steam cycle with advanced cycles. This study aimed assess techno-economic feasibility coal-fired plant based on combustion different Brayton These included single cycles, recompression supercritical CO2, simple cycle, xenon well combined cycles helium, nitrogen The break-even electricity price, which was estimated using present value method, were used key performance indicators. A parametric also conducted impact thermodynamic parameters. showed that case a had best overall performance, while among cases. former characterised 38.9%, higher than reference without (38.0%). Such price 71.2 €/MWel,neth, corresponding cost avoided 16.3 €/tCO2.
