The round tip efficiency of Isothermal compressed air energy storage system is high compared to that of other compressed air energy storage systems. The temperature produced during compression as well as expansion for isothermal compressed air energy storage is deduced from heat transfer, with the aid of moisture in air.
Hence, hydraulic compressed air energy storage technology has been proposed, which combines the advantages of pumped storage and compressed air energy storage technologies. This technology offers promising applications and thus has garnered considerable attention in the energy storage field.
Hydraulic energy storage in the system has many advantages over the conventional CAES system, including quick start-up, the ability to provide “spinning reserve,” and voltage and frequency regulation to stabilize the associated power grid [35, 36].
