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) exploits the established principles of pumped storage hydropower, but extends the concept in a new direction: Down.
Underground pumped storage
High efficiency (80%+)
No exhaust stack or emissions
Very little land use
POWER MAGAZINE August, 2013 FEATURE STORY - "Let Gravity Store the Energy"
Gravity Power LLC—a startup based in Santa Barbara, California—has developed a low-cost, quick-start, and fast dynamic response energy storage technology that competes with classical pumped storage hydro and gas turbines for peaking and intermediate duty power generation. The system is simple, yet its potential is profound.
