In other words, a GES system stores electricity in the form of a heavy weight taken to higher elevations. When discharging, the weight is released to move
READ MOREGravity batteries might be the answer. The idea sounds simple – when there is plenty of green energy, the batteries use the power to lift a heavy weight either high into the air or to the top of a deep shaft. Then when the power is needed, winches gradually lower the weight, and produce electricity from the movement of the cables.
