3.1.5 Compressed Air Storage. Compressed Air Energy Storage (CAES) is an option in which the pressure energy is stored by compressing a gas, generally air, into a high pressure reservoir. The compressed air is expanded into a turbine to derive mechanical energy and hence run an electrical generator.

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.
