OverviewTypesCompressors and expandersStorageEnvironmental ImpactHistoryProjectsStorage thermodynamics
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.
The state of the art of the Compressed Air Energy Storage Technology (CAES) is presented, while focusing over the aspects of this technology which could be useful for the general professional public
Advancements in adiabatic CAES involve the development of high-efficiency thermal energy storage systems that capture and reuse the heat generated during compression. This innovation has led to
