Pumped storage hydropower facilities rely on two reservoirs at different elevations to store and generate energy. When other power plants generate more electricity than the grid needs, a PSH plant can use that power to pump water into the upper reservoir. Support CleanTechnica's work through a Substack subscription or on Stripe. This technology doesn't use chemistry to store energy, so can have a longer storage life as there are no concerns with chemical degradation. It is often mistakenly considered a tapped resource, but according to the U.
