Compressed air energy storage (CAES) is a method of compressing air when energy supply is plentiful and cheap (e.g. off-peak or high renewable) and storing it for later use. The main application for CAES is grid-scale energy storage, although storage at this scale can be less efficient compared to battery storage, due to heat losses.
There are only two salt-dome compressed air energy storage systems in operation today—one in Germany and the other in Alabama, although several projects are underway in Utah. Hydrostor, based in Toronto, Canada, has developed a new way of storing compressed air for large-scale energy storage. Instead of counting on a salt …
