The Nant de Drance pumped storage hydropower plant in Switzerland can store surplus energy from wind, solar, and other clean sources by pumping water from a lower reservoir to an upper one, 425 meters higher.
The Tâmega plant takes excess electricity from the grid, mostly generated by wind and solar power, and uses it to pump water from a lower reservoir to an upper one.
It''s incredible to see lights come on powered by water alone but also sobering to realize just how much water you''d need to power a typical home.
Pumped storage hydropower is the world''s largest battery technology, with a global installed capacity of nearly 200 GW – this accounts for over 94% of the world''s long duration energy storage capacity, well ahead of lithium-ion and other battery types.
Pumped hydroelectric stations use water storage as a battery. During grid peak periods, water from an upper reservoir is released through tunnels to a lower reservoir that is either manufactured or natural, such as a river.
The Department of Energy''s "Pumped Storage Hydropower" video explains how pumped storage works. The first known use cases of PSH were found in Italy and Switzerland in the 1890s, and PSH was first used in the United States in 1930.

In this video, Argonne representatives show STEM students how pumped storage hydropower (PSH) is a "Water Battery for Clean Energy."

This video explains how pumped storage power plants act as massive batteries, storing excess electricity by moving water uphill.
The system also requires power as it pumps water back into the upper reservoir (recharge). PSH acts similarly to a giant battery, because it can store power and then release it when needed. The Department of Energy's "Pumped Storage Hydropower" video explains how pumped storage works.
Many facilities, such as Drax’s Cruachan plant in Scotland, were built in the 1960s to store surplus electricity from nuclear plants. Today pumped hydro accounts for more than 90 per cent of global electricity storage, a lot of it in the US, according to the International Energy Agency. But more is needed.
A few even rely, as pumped storage does, on gravity. The Yakama Nation favors one of those. The tribe is in conversation with a company called ARES, for “advanced rail energy storage,” which this year plans to put its technology to a major test in a gravel quarry in Pahrump, Nevada.
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
With closed-loop PSH, reservoirs are not connected to an outside body of water. Open-loop pumped storage hydropower systems connect a reservoir to a naturally flowing water feature via a tunnel, using a turbine/pump and generator/motor to move water and create electricity.
Another gravity-based energy storage scheme does use water—but stands pumped storage on its head. Quidnet Energy has adapted oil and gas drilling techniques to create “modular geomechanical storage.”
