Schematic diagram of a compressed air energy storage (CAES) Plant. Air is compressed inside a cavern to store the energy, then expanded to release the energy at a convenient time. [...] Driven by global concerns about the climate and the environment, the world is opting for renewable energy sources (RESs), such as wind and solar.
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 .
There are several compression and expansion stages: from the charging, to the discharging phases of the storage system. 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 .
The performance of compressed air energy storage systems is centred round the efficiency of the compressors and expanders. It is also important to determine the losses in the system as energy transfer occurs on these components. There are several compression and expansion stages: from the charging, to the discharging phases of the storage system.
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.
A detailed understanding of compressed air energy storage systems paired with an in-depth comprehension of various expansion stages of air will form the basis for any selection criteria. The overall process of expansion is also crucial, so is fixing the operating pressure conditions as well as temperatures and flow rates.
