How it Works
The entire Quidnet module is built on conventional drilling technology and off-the-shelf hydropower equipment. Facilities operate with closed-loop water systems, designed for conservation against evaporative loss. The energy-storing rock bodies are non-hydrocarbon bearing and found abundantly throughout the world, intersecting with major electricity transmission and distribution hubs.
When electricity is abundant, it is used to pump water from a pond down a well and into a body of rock.
The well is closed, keeping the energy stored under pressure between rock layers for as long as needed.
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.
