Gravity Power sells turnkey, utility scale energy storage systems (also called GPPs) to entities that develop, own and operate such systems. Customers include developers, utilities and very large commercial users. The Gravity Power Plant (GPP) consists of a deep shaft with a massive piston hydraulically raised by pressurized water. During peak periods, or whenever stored energy is required, the piston descends, forcing water below it up through a penstock to drive a conventional Francis-type pump-turbine and generate power.
Funding target: $10,000 – $107,000 by 2/8/2019
