Addressing the risks of pumped storage hydropower for a net

Pumped storage hydropower can be part of the solution. It consists 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. When demand is lower than supply, power can be used to pump water back into the upper reservoir (recharge).

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 larg
