Gravitricity's GraviStore is an innovative gravity energy storage system that raises and lowers heavy weights in underground shafts, offering some of the best characteristics of lithium-ion batteries and pumped hydro storage.
So how is this best achieved? The energy a gravity-based storage system can store and discharge is a function of mass, gravity (which is constant) and the distance of the drop: this formula, Energy = mass x gravity x height, or E = mgh, will be familiar to physics and engineering students everywhere.
