Reasons for the low efficiency of supplementary air energy storage
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]
Store energy at low trough and sell at high trough
