Gravity Energy Storage Systems with Weight Lifting
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 energy converts back
