Gravity Power Grid-Scale Electricity Storage System

Gravity Power, LLC, a spin-off of LaunchPoint Technologies, Inc., is developing a revolutionary grid-scale electricity storage system. The company's new Gravity Power Module(GPM)^TM exploits the established principles of pumped storage hydropower, but extends the concept in a new direction: Down.

Pumped storage hydropower (PSH) is the only large-scale electricity storage technology widely used today, with over 120,000 megawatts of capacity worldwide. However, a new PSH installation typically takes 11 to 15 years to develop and an investment exceeding one billion dollars before a single watt of power is produced. It also has severe siting limitations due to the need for two large reservoirs at different elevations and the resulting environmental disruption.

In contrast, a GPM can be quickly installed underground with virtually no adverse environmental impacts. The modular, closed system has a very small footprint that can be sited almost anywhere electricity storage is needed. With a combination of proven pump-turbine technologies and ground-breaking system architecture, the GPM offers far superior operating characteristics and economics over conventional pumped hydro storage, compressed air energy storage, or batteries.
