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 adiabatic, diabatic, isothermal, or near-isothermal.
Adiabatic CAES systems use the heat generated during compression for this, temporarily storing it in a thermal storage. Diabatic systems do not store the heat from compression. Instead, they use natural
Compressed air energy storage (CAES) is a technology employed for decades to store electrical energy, mainly on large-scale systems, whose advances have been based on improvements in thermal
