How much land is needed for pumped hydro?
If the storage is mostly in the form of pumped hydro then 2-5 km 2 is required per million people for the upper + lower reservoirs. This is smaller than one tenth of the area of land required for the corresponding solar and wind energy systems that the storage supports. Most of the identified sites are not near significant rivers.
