Design issues for compressed air energy storage in sealed …
Abstract. Compressed air energy storage (CAES) systems represent a new technology for storing very large amount of energy. A peculiarity of the systems is that gas must be stored under a high pressure ( p = 10–30 MPa). A lined rock cavern (LRC) in the form of a tunnel or shaft can be used within this pressure range.
