Compressed-air-energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational as of 2024.
For the advanced adiabatic compressed air energy storage system depicted in Fig. 11, compression of air is done at a pressure of 2.4 bars, followed by rapid cooling. There is considerable waste of heat caused by the exergy of the compressed air. This occurs due to two factors.
The main limitation for this technology has to do with the start up, which is currently between 10 and 15 min because of the thermal stress being high. The air is first compressed to 2.4 bars during the first stage of compression. Medium temperature adiabatic compressed air energy storage system depicted in Fig. 13. Fig. 13.
Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
Researchers from the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, developed a 500-kW CAES system in Wuhu, China, in 2014 . In Japan, a 1-MW CAES plant adjacent to the Higashiizu wind farm of Tokyo Electric Power Company Holdings, Inc. was installed in Shizuoka Prefecture in 2017 .
The energy conversion in a CAES system can be summarized into five main stages. The first stage is air compression with simultaneous extraction of heat during charging, followed by storage the later, when the time of discharge comes, the air is routed to the expanders via the heat exchangers to be heated up and generate work.
