Quidnet's innovative GPS energy storage technology pumps water underground and stores it between impermeable rock layers. The rock performs like a natural spring and holds the water under pressure. When the project is called upon to supply electricity, the pressurized water is released to power a hydroelectric turbine that generates emission-free electricity. The entire process is closed loop to conserve water resources.
The technology is a form of pumped hydro storage, which currently provides over 90 percent of the world's energy storage capacity, but deployable in a wide and diverse swath of geographies previously considered unsuitable for pumped hydro development. This unique approach to energy storage offers a new, cost-effective, highly scalable tool that is key to unlocking the global clean energy future.
