Whereas pumped hydro is a type of energy storage that converts the water potential energy into kinetic energy then mechanical energy and finally electrical energy. The working principal of such systems is pumping the water to high levels into a reservoir during low demand periods.
Pumped storage hydropower can provide energy-balancing, stability, storage capacity, and ancillary grid services such as network frequency control and reserves. This is due to the ability of pumped storage plants, like other hydroelectric plants, to respond to potentially large electrical load changes within seconds.
Worldwide capacity of renewable power reached 2533 GW in 2019, but only 192 GW of installed power storage was available, 8 dominated by pumped hydro (see Figure 2), which provides nearly 80% of the global storage capacity of 800 GWh. 9 In other words, 800 GWh of storage capacity for 192 GW of installed storage can at best provide …
