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.
Edinburgh-based startup Gravitricity is set to turn one of Europe’s deepest mines into the continent’s first-ever gravity energy storage system.
Using gravity and solid weights to store energy makes perfect sense, but only if you do it underground, says Gravitricity Commercial Director Robin Lane. The idea of using gravity to store energy is not new.
Gravity Storage allows for large quantities of power to be stored for long periods of time at a high efficiency rate and with no elevation required. Still, construction, maintenance and site-related aspects must be considered. Energy Vault's core product is a kinetic storage system that consists of multiple cranes and cement-like blocks.
Among these we can find: This solution is offered by companies like Gravity Power. When compared to conventional pumped hydro storage systems, Gravity Power removes siting constraints by moving the reservoir to underground, bringing more flexibility to where it can be installed.

Other gravity-based storage companies have their own twists on the technology. The idea behind California-based Gravity Power is just a small step away from pumped hydro: It uses renewable energy to pump water under a heavy piston and lift it. When power is needed, the piston weight is released, forcing the water through a hydroelectric generator.
The company claims its technology GraviStore is suitable for both short-duration, high power energy storage applications and long-duration, high energy applications.
