Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
The reverse operation of both components to each other determines their design when integrated on a compressed air energy storage system. The screw and scroll are two examples of expanders, classified under reciprocating and rotary types.
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.
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).
For the advanced adiabatic compressed air energy storage system depicted in Fig. 11, compression of air is done at a pressure of 2.4 bars, followed by rapid cooling. There is considerable waste of heat caused by the exergy of the compressed air. This occurs due to two factors.
Using this technology, compressed air is used to store and generate energy when needed . It is based on the principle of conventional gas turbine generation. As shown in Figure 2, CAES decouples the compression and expansion cycles of traditional gas turbines and stores energy as elastic potential energy in compressed air . Figure 2.
