Carbon capture and sequestration (CCS) technologies have emerged as a promising technique to prevent greenhouse gas emissions of fossil fuel-fired power plants. In recent years oxy-fuel combustion-based CCS technique has gained a lot of attention and consideration because of its cost-effective CO2 capture. The present review article outlines the progress made in carbon capture and sequestration (CCS) based on oxy-fuel combustion by incorporating an air separation unit (ASU) and carbon dioxide purification and compression unit (CPU). The present article discusses the major components of the oxy-fuel combustion power plant and compares various novel configurations of oxy-fuel power generation systems in terms of energy penalty, auxiliary energy consumption, CO2 purity, and CO2 capture efficiency. This review also focuses on modifications to oxy-fuel combustion power generation systems such as pressurized oxy-fuel combustion, flue gas enriched oxy-fuel combustion, and few advanced oxy-fuel configurations. This review article has addressed the techno-economic and thermodynamic aspects of the oxy-fuel combustion-based carbon capture and sequestration (CCS) method.
