The most efficient air energy storage technology

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. Supercapacitors and lithium-ion batteries are the efficiency champions at 90-95%, meaning almost all the energy you store comes back when you need it. Pumped hydro storage is still respectable at 70-85%, while compressed air systems trail behind at 40-70%.
