(c) Long duration energy storage


Pumped-storage hydropower is a type of hydroelectric power generation used for long-duration energy storage. It works by pumping water from a lower elevation reservoir to a higher elevation during periods of low electricity demand. During periods of high electricity demand, the stored water is released back down to the lower reservoir, generating electricity through turbines.
