How many pumped hydro energy storage sites are there?

Our analysis has identified 616,818 low cost closed-loop, off-river pumped hydro energy storage sites with a combined storage potential of 23.1 million GWh.

What is pumped hydro energy storage?

Pumped hydro energy storage was originally developed to manage the difference between the daily cycle of electricity demand and the baseload requirements for coal and nuclear generators: Energy was used to pump water when electricity demand was low at night, and water was then released to generate electricity during the day.

How many GWh is a pumped hydro energy storage capacity?

The total global storage capacity of 23 million GWh is 300 times larger than the world’s average electricity production of 0.07 million GWh per day. 12 Pumped hydro energy storage will primarily be used for medium term storage (hours to weeks) to support variable wind and solar PV electricity generation.

Could pumped storage transform hydroelectric projects?

New research released Tuesday by Global Energy Monitor reveals a transformation underway in hydroelectric projects — using the same gravitational qualities of water, but typically without building large, traditional dams like the Hoover in the American West or Three Gorges in China. Instead, a technology called pumped storage is rapidly expanding.

What is the area requirement for pumped hydro energy storage?

Another perspective to understand the scale of the area requirement for pumped hydro energy storage is to compare to the land needed for the associated generation. A solar farm with a daily output of 1 GWh requires an area of land that is about 300 Ha (assuming 18% efficient modules, a capacity factor of 16%, and a module packing density of 50%).

What is pumped hydropower storage (PHS)?

Note: PHS = pumped hydropower storage. The transition to renewable energy sources, particularly wind and solar, requires increased flexibility in power systems. Wind and solar generation are intermittent and have seasonal variations, resulting in increased need for storage to guarantee that the demand can be met at any time.
