How it Works

The entire module is produced with conventional drilling processes and standardized hydro-mechanical power conversion subcomponents. Modules operate with a closed-loop water system, designed for conservation against evaporative loss. Compatible geologies for siting the modules are non-hydrocarbon bearing and found abundantly throughout the world, intersecting with major electricity transmission and distribution networks.

1

When there is surplus electricity, it is used to pump water from a pond down a well and held under pressure.

2

The well is closed, keeping the energy stored under pressure for as long as needed.

3

When electricity is needed, the well is opened to let the pressurized water pass through a turbine to generate electricity, and return to the pond ready for the next cycle.

About Quidnet Energy

Houston-based Quidnet Energy is an energy storage company that uses the subsurface as a sustainable natural resource. Quidnet Energy’s patented Geomechanical Energy Storage technology utilizes excess electricity from the grid to store water beneath the ground under pressure, delivering that energy later to provide firm, reliable power to the grid.
