This paper presents a hybrid system integrating compressed air energy storage (CAES) with pressurized water thermal energy storage (PWTES). The open type isothermal compressed air energy storage (OI-CAES) device is applied to the CAES subsystem to achieve near-isothermal compression of air.
The special thing about compressed air storage is that the air heats up strongly when being compressed from atmospheric pressure to a storage pressure of approx. 1,015 psia (70 bar). Standard multistage air compressors use inter- and after-coolers to reduce discharge temperatures to 300/350°F (149/177°C) and cavern injection air temperature
Compressed-air energy storage (CAES) is a technology in which energy is stored in the form of compressed air, with the amount stored being dependent on the volume of the pressure storage vessel, the pressure at which the air is stored, and the temperature at which it is stored. A simplified, grid-connected CAES system is shown in Fig. 14.1 [1].
The utilization of the potential energy stored in the pressurization of a compressible fluid is at the heart of the compressed-air energy storage (CAES) systems.
