An Exergy Analysis Of Recompression Supercritical Co2 Cycles With And Without Reheating, Ricardo Vasquez Padilla, R G. Benito, Wes Stein

Dr Ricardo Vasquez Padilla

Concentrated Solar Power using supercritical CO₂ (S-CO₂) recompression Brayton cycles offer advantages of similar and even higher overall thermal efficiencies compared to power cycles using superheated or supercritical steam. The high efficiency and compactness of S-CO₂, as compared with steam Rankine cycle at the same high temperature, make this cycle attractive for central receiver applications, since both attributes lead to decrease in levelized cost of energy and therefore make this technology economically feasible. The current research in S-CO₂ is focused on thermodynamic analysis and system components. In this paper energy and exergy analyses of …
