Compressed air | energy.gov
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.
