Research has shown that isentropic efficiency for compressors as well as expanders are key determinants of the overall characteristics and efficiency of compressed air energy storage systems . Compressed air energy storage systems are sub divided into three categories: diabatic CAES systems, adiabatic CAES systems and isothermal CAES systems.
The number of sites available for compressed air energy storage is higher compared to those of pumped hydro [, ]. Porous rocks and cavern reservoirs are also ideal storage sites for CAES. Gas storage locations are capable of being used as sites for storage of compressed air .
Analysis of compressed air energy storage systems is usually conducted by taking both compression and expansion stages into consideration using ideal gas laws. Expanders’ mechanical work is first transformed.
Energy storage systems are a fundamental part of any efficient energy scheme. Because of this, different storage techniques may be adopted, depending on both the type of source and the characteristics of the source. In this investigation, present contribution highlights current developments on compressed air storage systems (CAES).
The enthalpy transformation of air in the various types of compressed air energy storage systems varies depending on the expansion trajectories. The expansion stage for diabatic and adiabatic compressed air energy storage systems are described as isentropic processes that occur in the absence of heat transfer within the environment.
The main limitation for this technology has to do with the start up, which is currently between 10 and 15 min because of the thermal stress being high. The air is first compressed to 2.4 bars during the first stage of compression. Medium temperature adiabatic compressed air energy storage system depicted in Fig. 13. Fig. 13.
