Energy and exergy analysis of adiabatic compressed air energy storage system

Simulations of processes of loading and unloading of compressed air storage were performed and then places where exergy destruction occurs were identified. The biggest exergy destruction occurs in the compressors (276.191 MWh/cycle in total) and turbines (190.394 MWh/cycle in total). Major destruction of exergy was also reported at control valve V2 (103.688 MWh/cycle). Round trip efficiency of the system is 50%.
