Abstract:

Compressed air energy storage system stores electricity by compressing air and the stored compressed air is released to produce electricity by driving an expander during the demand period. Compressed air energy storage systems have a wide range of potential applications in generation, transmission and utilisation of electricity. It has become a hot topic among energy storage research community. This paper reviews the state-of-the-art developments of such a technology including the operating principles, function and current status of development. Classification, technical characteristics, key components and system performance of different types of compressed air energy storage systems are also analysed. Finally, remarks are made on the further development of the compressed air energy storage technology.

Key words: energy storage, compressed air, research progress
