Abstract
Energy storage is a natural process as old as the universe itself. The energy present at the initial formation of the universe are been stored in stars such as the sun, and is now being used by humans directly (e.g. through solar heating), or indirectly (for e.g. by growing crops or converting into electricity in solar cells). The compressed air energy storage (CAES) is at a turning point. Compressed air energy storage technology stores low cost off-peak energy, in the form of compressed air in an underground reservoir. The air is then released during peak load hours and heated with the exhaust heat of a standard combustion turbine. This heated air is converted to electrical energy through expansion turbines. CAES components also have the advantage of being the most readily part available. Gas turbines, air compressors, recuperators, injection and extraction wells, and other CAES components technologies operate already under streamlined economies of scale. Other, more experimental storage technologies, such as fuel cells, flywheels, or massive batteries are not close enough of reaching cost parity with CAES installations.
