Abstract. - With an increasing capacity of wind energy globally, wind-driven Compressed Air Energy Storage (CAES) technology has gained significant momentum in recent years. However, unlike traditional CAES systems, a wind-driven CAES system operates with more frequent fluctuations due to the intermittent nature of wind power.
1.1. Review of standalone liquid air energy storage In the standalone LAES system, renewable generation or off-peak electricity is consumed to liquefy air (i.e., air liquefaction process); at peak time, the liquid …

Air is usually compressed adiabatically in the compressor. As the operating speed of compressors can be several thousand rpm, heat generated during compression cannot be sufficiently transmitted to the environment in such a short time. It is for this reason that compressor efficiency is limited. Isothermal compression could be …
Second-generation CAES in Germany introduces heat storage devices, which capture heat from the air during the compression and release this heat to the air during the expansion process. CAES''s low conversion efficiency (50 %) could thereby be increased to 70 %, close to the value of a storage battery.
2.1. How it all began The fundamental idea to store electrical energy by means of compressed air dates back to the early 1940s [2] then the patent application "Means for Storing Fluids for Power Generation" was submitted by F.W. Gay to the US Patent Office [3]..
