Quidnet Energy, which has an office in Saratoga Springs, has achieved two key milestones in its projects with the U.S. Department of Energy’s Water Power Technology Office (WPTO) and Advanced Research Projects Agency–Energy (ARPA-E), to commercialize the company’s geomechanical pumped storage (GPS) technology.
Quidnet partnered with the WPTO through its HydroWIRES Initiative to develop an innovative reversible injector-generator that will enable deployment of modular hydropower conversion in high-pressure pumped hydro applications such as for Quidnet’s GPS technology. The milestone was achieved by the completion of system-level design and engineering as well as testing of key operating components in an industrial machining facility in New York state, officials said.
Quidnet pumps water underground and stores it in-between layers of rock. The natural elasticity of the rock performs like a spring and holds the water under pressure until it is needed, at which time it is released through a hydroelectric turbine to produce electricity to send back to the grid.
Quidnet is working with ARPA-E through their Duration Addition to electricitY Storage (DAYS) program to develop the GPS resource in key power markets across the U.S. by planning and executing exploratory wells to characterize, evaluate, and validate this geologic resource.
