Recent advancements have focussed on optimising thermodynamic performance and reducing energy losses during charge–discharge cycles, while innovative configurations have been proposed to integrate multi-generation outputs such as cooling, heating, desalinated water and hydrogen production.
[pdf] 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.
