Pumped hydro and Gravity Power both use hydraulic power and a liquid pump or turbine to move water or produce electricity. 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.
