What is compressed air energy storage?
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.
Where can compressed air energy be stored?
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 .
How many kW can a compressed air energy storage system produce?
CAES systems are categorised into large-scale compressed air energy storage systems and small-scale CAES. The large-scale is capable of producing more than 100MW, while the small-scale only produce less than 10 kW . The small-scale produces energy between 10 kW - 100MW .
