The 300 MW compressed air energy storage station in Yingcheng, central China''s Hubei Province, started operation on Tuesday. With the technology known as "compressed air energy storage", air would be pumped into the underground cavern when power demand is low while the compressed air would be released to generate power

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].However, until the late 1960s the development of compressed air

1.1. Compressed air energy storage concept. CAES, a long-duration energy storage technology, is a key technology that can eliminate the intermittence and fluctuation in renewable energy systems used for generating electric power, which is expected to accelerate renewable energy penetration [7], [11], [12], [13], [14].

In adiabatic compressed air energy storage systems (Fig. 7.2), the heat of compression is stored in one or more separate storage facilities so that it can be reused to heat up the air when it is withdrawn from the storage cause this dispenses with the addition of combustion gas, this can be considered a pure power-to-power storage
