Solid-based gravity energy storage (GES) technology is a new type of large-scale, mechanical energy storage technology similar to the widely used pumped hydro storage [8, 9]. Gravity energy storage has high investment costs for installed capacity while low for energy storage. Thus, gravity energy storage is particularly
READ MOREGravity energy storage is getting noticed by investors and governors in large part for being so simple – all one needs are heavy objects, winding gear, and either a high tower or a very deep drop. There are minimal raw material requirements, a small land footprint per kWh, no harmful chemicals, low operational costs and high round-trip
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.
