Pumped Storage Hydropower | Department of Energy

Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration 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. The system also requires power as it pumps water back into the upper reservoir (recharge).

Tank Thermal Energy Storage

Tank thermal energy storage (TTES) is a vertical thermal energy container using water as the storage medium. The container is generally made of reinforced concrete, plastic, or stainless steel (McKenna et al., 2019 ). At least the side and bottom walls need to be perfectly insulated to prevent thermal loss leading to considerable initial cost ...

SummaryPotential technologiesOverviewHistoryWorldwide usePump-back hydroelectric damsSee alsoExternal links

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…

Surface water

Human-made surface water is water that can be continued by infrastructures that humans have assembled. This would be dammed artificial lakes, canals and artificial ponds (e.g. garden ponds) or swamps. [3] The surface water held by dams can be used for renewable energy in the form of hydropower. Hydropower is the forcing of surface water sourced ...
