Green solution for power generation by adoption of adiabatic CAES system

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 (T-a) and overall pressure ratio (Rc). The effect of these variables on the generated power (W-gen), energy ratio (ER), efficiency (eta), and other performance parameters is evaluated. The results showed that adiabatic CAES offered relatively high energy storage efficiency, compared with conventional CAES technology. (c) 2012 Elsevier Ltd. All rights reserved.
