Compressed air energy storage technology and development
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]
Air energy storage capacity selection
In order to use air storage in vehicles or aircraft for practical land or air transportation, the energy storage system must be compact and lightweight. and are the engineering terms that define these desired qualities. As explained in the thermodynamics of the gas storage section above, compressing air heats it, and expansion cools it. Therefore, practical air engines require heat exchan. [PDF Version]
