How does a water battery store energy?
Water batteries store excess energy from sources like solar and wind by pushing water up into the battery's top pool, where it waits, charging the water battery. This process allows for energy storage when other energy sources produce more electricity than is immediately needed.
How does pumped storage hydropower work?
PSH acts similarly to a giant battery, because it can store power and then release it when needed. The Department of Energy's "Pumped Storage Hydropower" video explains how pumped storage works. The first known use cases of PSH were found in Italy and Switzerland in the 1890s, and PSH was first used in the United States in 1930.
