Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be , diabatic, , or near-isothermal.

CAES systems are often considered an environmentally friendly alternative to other large-scale energy storage technologies due to their reliance on naturally occurring resources, such as for air storage and ambient air as the working medium. Unlike , which require the extraction of finite resources such as lithium and cobalt, CAES has a minimal environmental footprint during its lifecycle.

Is compressed air energy storage a solution to country's energy woes?
"Technology Performance Report, SustainX Smart Grid Program" (PDF). SustainX Inc. Wikimedia Commons has media related to Compressed air energy storage. Solution to some of country's energy woes might be little more than hot air (Sandia National Labs, DoE).
Is compressed air cheaper than a mass-produced battery?
Compressed air costs are potentially lower; however, advanced pressure vessels are costly to develop and safety-test and at present [when?] are more expensive than mass-produced batteries. As with electric storage technology, compressed air is only as "clean" as the source of the energy that it stores.
