What is pumped storage hydropower?

Pumped storage hydropower stores energy and provides services for the electrical grid. This Review discusses the types, applications and broader effects of this form of grid-scale energy storage.

How many pumped hydro energy storage sites are there?

A global atlas of 616,000 pumped hydro energy storage sites. In Proceedings of the ISES Solar World Congress 2019 1–5 (International Solar Energy Society, 2019). Lu, B., Stocks, M., Blakers, A. & Anderson, K. Geographic information system algorithms to locate prospective sites for pumped hydro energy storage. Appl. Energy 222, 300–312 (2018).

What are the potential services and impacts of pumped storage hydropower?

These potential services and impacts are discussed in this section. Fig. 4: Economic and environmental factors and impacts. Pumped storage hydropower provides energy storage for power systems, ancillary grid services and water management, but also has economic and environmental impacts. GHG, greenhouse gas; VRE, variable renewable energy.

Can pumped storage hydropower be used in areas that are not practical?

Forms of PSH that are seawater-based, small-scale or based at former mining sites could potentially mitigate some of these impacts and enable PSH development in areas where it is not currently practical. Pumped storage hydropower stores energy and provides services for the electrical grid.
