Any CAES system is charged by using electricity to drive air compressors, resulting in compressed air and heat. In DCAES, the heat is extracted by using heat exchangers (HEX) and dissipated (being of low grade and therefore of low value), whereas the pressurized air is stored in a dedicated pressure vessel, herein referred to as the
In this field, one of the most promising technologies is compressed-air energy storage (CAES).

A different type of CAES that aims to eliminate the need of fuel combustion, known as Advanced Adiabatic Compressed Air Energy Storage (AA-CAES), has recently been developed. AA-CAES stores the heat created during the initial air compression for use in the electricity generation section of the cycle. While this would entirely eliminate the need
Liu et al. [ 45] calculated the energy density of compressed air to be 370 kJ/kg under the storage pressure of 20 MPa, which is much lower than that of diesel or gasoline. To ensure the continuous supply of compressed air during the operation, the power of the engine or the vehicle speed must be limited.
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.
