Structure of air energy unit storage box

CAES works in the process: the ambient air is compressed via compressors into one or more storage reservoir (s) during the periods of low electricity demand (off-peak) and the energy is stored in the form of high pressure compressed air in the reservoir (s); during the periods. In compressed air energy storages (CAES), electricity is used to compress air to high pressure and store it in a cavern or pressure vessel. Particularly, in North America, China and other areas, where rock salt layers are widely distributed, using underground spaces formed in the rock salt.
