Quidnet Energy develops long-duration geomechanical energy storage systems. This new form of underground pumped-storage hydroelectric power generation utilizes existing natural resources. Each module is manufactured using traditional drilling processes and standardized hydromechanical energy conversion components. The modules operate within a closed-loop water system designed to prevent energy loss through evaporation. When excess power is available, it is used to pump water from a pond into a borehole, maintaining it under pressure. The borehole is then closed, maintaining the stored energy under pressure for as long as needed. When power is needed, the borehole is opened, allowing the pressurized water to pass through a turbine to generate electricity and return to the pond for the next cycle.
