Can a seawater pumped storage system be used as drinking water?

By combining a seawater pumped storage system and a desalination plant, using reverse osmosis (RO) to turn seawater into drinking water, we can help provide fresh water in arid coastal areas and environmentally friendly energy at the same time. The ocean would be used as the lower reservoir, with the upper reservoir in nearby coastal mountains.

What is pumped storage?

The water flows into the lower basin. Pumped storage is economically and environmentally the most developed form of storing energy during base-load phases while making this energy available to the grid for peaking supply needs and system regulation. Voith has delivered this technology since its inception.

What is a closed-loop pumped storage hydropower system?

A closed-loop pumped storage hydropower system (PSH) is one where reservoirs are not connected to an outside body of water. In contrast, open-loop systems connect a reservoir to a naturally flowing water feature via a tunnel.

What is pumped storage hydropower?

Pumped storage hydropower (PSH) is the most dominant form of energy storage on the electric grid today. It plays an important role in integrating more renewable resources onto the grid. PSH can be characterized as open-loop or closed-loop, with open-loop PSH having an ongoing hydrologic connection to a natural body of water.

What is a pumped storage power station?

Their special feature: They are an energy store and a hydroelectric power plant in one. If there is a surplus of power in the grid, the pumped storage power station switches to pumping mode – an electric motor drives the pump turbines, which pumps water from a lower reservoir to a higher storage basin.

What is the energy storage capacity of a pumped hydro facility?

The energy storage capacity of a pumped hydro facility depends on the size of its two reservoirs. At times of high demand - and higher prices - the water is then released to drive a turbine in a powerhouse and supply electricity to the grid. The amount of power generated is linked to the size of the turbine.
