The supercritical carbon dioxide cycle run on the utilization of carbon dioxide uses emissions from fossil fuel-fired power plants. In this study, the supercritical carbon dioxide cycle is powered by solar energy using heliostat fields. The operating range of supercritical carbon dioxide cycle permits for the integration of low-temperature cycles for effective utilization of the heat remaining unutilized in it. This paper considers the supercritical carbon dioxide cycle for its energy analysis. It aims for the optimal utilization of heat available with the exhaust from the sCO2 cycle. Results obtained based on parametric variation have been presented and analyzed here. At the turbine inlet pressure of 290 bar, the turbine inlet temperature of 700oC in sCO2 cycle and cycle efficiency is obtained as 16.56 % and specific work output is 174.6 KJ/kg of sCO2.
