Title: An Evaluation of High-Temperature Energy Storage with Closed Gas Turbine Discharge Cycle
Keywords: energy storage, molten salts, air Bryton Cycle, organic Rank

Abstract: his paper presents research on improving the efficiency of air-based pumped heat energy storage. We used a simulation tool to model the charging and discharging cycles of the reference case. The discharge cycle of the baseline system is inefficient because it loses a lot of low-potential residual heat. Organic Rankine cycle is the technology used to convert this thermal energy into electricity. Adding it as a bottoming cycle increased the generated power by 6% and the round-trip efficiency by 5.6%.
