Series C · Houston, Texas · founded 2015 · 8 employees$29Mraised▾
Provider of pumped hydro based energy storage system. It is developing a grid scale energy storage system by pumping in water in depleted oil wells. The water injection is done under high pressure to pressurize the stone bed which in turn later would be released to run turbines by ejecting the water from the well. As the rock is compressed, the energy is stored. Opening the well allows the pressurized water to be released to spin a turbine to create energy.
