In this work the use of compressed air energy storage with using the high compressor discharge temperature is discussed and analyzed. Performance is calculated for adiabatic (CAES) and compared with conventional systems. The operating variables in this study are discharge air mass flow (m˙a), ambient air temperature (Ta) and overall pressure ratio (Rc). The effect of these variables on the generated power (W˙gen), energy ratio (ER), efficiency (η), and other performance parameters is evaluated. The results showed that adiabatic CAES offered relatively high energy storage efficiency, compared with conventional CAES technology. ► The use of CAES with using the high compressor discharge energy is analyzed. ► Performance of adiabatic CAES is calculated and compared with conventional systems. ► This system offered relatively high energy storage efficiency. ► The effect of variation of m˙, Ta, and Rc on some performance parameters is analyzed. ► The results showed superior performance of the adiabatic CAES system.
