Pumped-storage hydroelectricity
OverviewPotential technologiesBasic principleTypesEconomic efficiencyLocation requirementsEnvironmental impactHistory
Pumped storage plants can operate with seawater, although there are additional challenges compared to using fresh water, such as saltwater corrosion and barnacle growth. Inaugurated in 1966, the 240 MW Rance tidal power station in France can partially work as a pumped-storage station. When high tides occur at off-peak hours, the turbines can be used to pump more seawater into the reservoir than the high tide would have naturally brought in. It is the only large
