How does a compressed air energy storage system work?
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.
What determinants determine the efficiency of compressed air energy storage systems?
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.
What is compressed air energy storage (CAES)?
In compressed air energy storages (CAES), electricity is used to compress air to high pressure and store it in a cavern or pressure vessel. During compression, the air is cooled to improve the efficiency of the process and, in case of underground storage, to reach temperatures comparable to the temperature at storage depth.
What is the process of energy storage & release in compressed air?
