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 into ...

Future Energy The Fall and Rise of Gravity Storage Technologies
Pumped hydro and Gravity Power both use hydraulic power and a liquid pump or turbine to move water or produce electricity. The difference is that the liquid medium in pumped hydro is the energy storage medium. The pump or turbine sits between the two water reservoirs and is used to move the water up or down the hill.
