Abstract. Large-scale e nergy storage technology is crucial to maintaining a high-proportion renewable energy power system stability and. addressing the energy crisis and environmental problems
Gravity-based storage helps by acting as a buffer to help stabilize and improve grid reliability. The ability to seamlessly balance supply and demand is one of the greatest benefits of gravity-based storage. Whenever energy is in surplus like when solar or wind generation is high, the excess energy is stored by lifting weights or sending water
Principle of Operation. Gravity energy storage (GES) is an innovative technology to store electricity as the potential energy of solid weights lifted against the Earth''s gravity force. When surplus electricity is available, it is used to lift weights. When electricity demand is high, the weights descend by the force of gravity and potential

Gravity energy storage is a form of mechanical energy storage that uses the earth''s gravity to store energy. The energy is stored in the form of potential energy, which is the energy that an object possesses due to its position relative to other objects. The higher an object is placed, the greater its potential energy.
