Thermodynamic analysis of CAES/TES systems for renewable energy plants

A thermodynamic analysis is presented for an energy storage system without combustion and including thermal recuperation (adiabatic compressed air energy strong (CAES)). The storage volume is optimized and a system layout with thermal storage (TES) and variable configuration is designed. The proposed system is simulated in order to have a first estimate of its energy recovery efficiency. (C) 2007 Elsevier Ltd. All rights reserved.
