In the Compressed Air Energy Storage (CAES) systems, the energy is stored in form of pressure energy, by means of a compression of a gas (usually air) into a reservoir. When energy is required, the gas is expanded in a turbine and the energy stored in the gas is converted in mechanical energy available at the turbine shaft.
Storage of energy using mechanical energy storage systems is conducted by transforming the energy into both mechanical and electrical energy. During off-peak when demand is low, the electrical energy is converted to mechanical energy via the principle of potential, kinetic or even pressurized gas.
