Compressed air energy storage is not a new concept. A 290-megawatt compressed air storage plant went online in 1978 in Huntorf, Germany, and remains in operation today.
This energy storage system functions by utilizing electricity to compress air during off-peak hours, which is then stored in underground caverns. When energy demand is elevated during the peak hours, the stored compressed air is released, expanding and passing through a turbine to generate electricity.
A-CAES was first proposed in 1972 [17] g. 2 illustrates the working principle of A-CAES: the compression heat of the compressor is used to heat the high-pressure air at the inlet of the expander instead of combustion chamber, and the input and output useful energy are only involved in electrical energy. ...
