"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).
Compressed air energy storage project profitability
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. [PDF Version]
