Our study assessed the proposed new PSH concepts and technology innovations to identify the most promising future PSH technologies and configurations that may lead to new PSH deployment, as well as to identify dead-end concepts that are not on a realistic path to becoming a deployable technology.
NREL experts are developing tools and partnering with industry to unlock the full potential of pumped storage hydropower (PSH)—a form of hydropower used to generate electricity, store energy, and provide grid services.
For example, Obermeyer Hydro, Inc. is developing a PSH technology using submersible pump-turbines and motor-generators, where both the pump-turbine and motor-generator can be submerged in a vertical shaft (i.e., well), avoiding the need
This transformation can be achieved in various ways, such as adding water pumps between upstream and downstream hydropower stations, building upper reservoirs, and installing new reversible...
Find out in this animation how GE Vernova''s Hydro Power Pumped Storage technology works, and how it contributes to a better integration of variable energies on the grid.
While lithium-ion dominates new energy storage installations, pumped hydro still represents more than 90% of the world''s storage of electricity for the grid and many of these facilities can enable several hours of low-emissions energy at a time.
An additional 78,000 MW in clean energy storage capacity is expected to come online by 2030 from hydropower reservoirs fitted with pumped storage technology, according to this working paper from the International Hydropower Association (IHA).
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.

A new US energy storage project will adapt the power of pumped storage hydro to subsea locations near offshore wind farms and coastal cities.
