Compressed air energy storage has a significant impact on the energy sector by providing large-scale, long-duration energy storage solutions. CAES systems can store excess energy during periods of low demand and release it during peak demand, helping to balance supply and demand on the grid.
In times of excess electricity on the grid (for instance due to the high power delivery at times when demand is low), a compressed air energy storage plant can compress air and store the compressed air in a cavern underground. At times when demand is high, the stored air can be released and the energy can be recuperated.
The compressed air storages built above the ground are designed from steel. These types of storage systems can be installed everywhere, and they also tend to produce a higher energy density. The initial capital cost for above- the-ground storage systems are very high.

An efficient compressed air storage system will only be materialised when the appropriate expanders and compressors are chosen.
