The Gravitricity system Gravity energy storage systems depend on the principle of lifting one or more solid masses a vertical distance in order to increase their gravitational potential energy. The system must then be reversible to allow the lowering of the weight (s) to result in useful release of the stored energy, less any efficiency losses.
gravity energy storage technology (SGES)). to store or release elec tricity. This technology accomplish es energy storage by converting the electrical energy in the power system to the gravitational potential energy of the weight through electromechanical equipment.
