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.
Future energy pumped hydro provides storage for hours to weeks and is overwhelmingly dominant in terms of both existing storage power capacity and storage energy volume.
Seasonal pumped hydropower storage (SPHS) can provide long-term energy storage at a relatively low-cost and co-benefits in the form of freshwater storage capacity. We present the first estimate of the global assessment of SPHS potential, using a novel plant-siting methodology based on high-resolution topographical and hydrological data.
Pumped hydro continues to be much cheaper for large-scale energy storage for several hours to weeks. Most existing pumped hydro storage is river-based in conjunction with hydroelectric generation.
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.
The Scottish Government has long been supportive of pumped hydro storage capacity, as it believes that pumped hydro storage will play a key role in the energy transition. The Net Zero and Energy Secretary continued:
