Low-temperature Adiabatic Compressed Air Energy Storage (LTA-CAES) represents a new approach to realize non-fuel consuming CAES. The approach aims at comparatively low storage temperatures of 95–200 °C. It makes use of the fact that cycle efficiency of A-CAES plants is not governed by the Carnot efficiency.
Abstract. A compressed air energy storage (CAES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems, and is most appropriate for large-scale use and longer storage applications. In a CAES system, the surplus electricity to be stored is used to produce compressed air at high pressures.
Compressed air has been used for energy storage since the 1970s in Huntorf, Niedersachsen, Germany and since the 1990s in McIntosh, Alabama, USA. In these two facilities, of respectively ~1 GWh ...

Inter-cooling between the compressor stages reduces the work required for compression (ICI to ICIII in Figure 3). After the compression, a cooling is required (ICIV) to cool down the air to the permissible inlet temperature of the cavern (50 °C). During charging, the air mass flow rate is kept at 108 kg/s [13-14].
The 110 MW McIntosh plant can operate for up to 26 h at full power. The compressed air is stored in a salt cavern. A recuperator is operated to reuse the exhaust heat energy. This reduces the fuel consumption by 22–25% and improves the cycle efficiency from ∼42% to ∼54%, in comparison with the Huntorf plant.
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to …
