What is pumped storage?
Pumped storage is the process of storing energy by using two vertically separated water reservoirs. Water is pumped from the lower reservoir up into a holding reservoir. Pumped storage facilities store excess energy as gravitational potential energy of water.
How does pumped hydro storage work?
Water flows from the upper reservoir, downhill. As it moves, it passes through turbines to generate electricity. One of the key advantages of pumped hydro storage is its large-scale storage capacity. This technology has the potential to store massive amounts of energy.
Why do we need pumped Energy Storage?
Because of its efficiency in hoarding excess energy, it’s like having a secret energy stash to use whenever there’s a blackout looming.
