(PSH) is the most widely used and highest-capacity form of grid-energy storage. In PSH, water is pumped from a lower reservoir to a higher reservoir, which can then be released through turbines to produce energy. An alternative PSH proposal uses aproprietary high-density liquid, 2+1⁄2 times denser than water, which requires a smaller(elevation. Gravity energy storage technology (GES) depends on the vertical movement of a heavy object in a gravitational field to store or release electricity. This technology accomplishes energy storage by converting the electrical energy in the power system to the gravitational potential energy of the weight through electromechanical equipment.
