Exergy analysis and performance improvement of direct steam-generated solar-based transcritical CO2 Rankine cycle with energy storage

In this particular study, the researchers conducted energy and exergy analyses of a solar-based transcritical CO2 Rankine cycle in order to improve its performance by integrating a regenerator and an energy storage unit. For the assessment, the system's features are drawn from genuine experimental research undertaken at Doshisha University in Kyoto, Japan. The effects of employing a regenerator and an energy storage tank were examined theoretically in order to determine the potential for enhancing the performance of the cycle. According to the data analysis, there has been a substantial boost in the energy produced, registering an impressive 22.7% improvement.
