How Pumped Storage Hydropower Works | Department of Energy

PSH facilities store and generate electricity by moving water between two reservoirs at different elevations. Vital to grid reliability, today, the U.S. pumped storage hydropower fleet includes about 22 gigawatts of electricity-generating capacity and 550 gigawatt-hours of energy storage with facilities in every region of the country.

The Fall and Rise of Gravity Storage Technologies

The difference is that the liquid medium in pumped hydro is the energy storage medium. The pump or turbine sits between the two water reservoirs and is used to move the water up or down the hill. In the Gravity Power system, the water only acts as a carrier of hydraulic force, pushing up the singular, heavy mass, like a giant piston.
