Compressed Air 101: The Basics

This action reduces the volume of the air, causing its pressure to increase. Cooling: As air is compressed, it heats up. Most compressors have mechanisms (like intercoolers or aftercoolers) to cool the compressed air and make the process more efficient. Storage: The compressed air is then directed into a storage tank.

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. Unlike ...
