what components does pumped storage include
What is pumped hydro and how does it work?
Pumped hydro, the simple concept of using excess energy to pump water up a hill and hold it there until it''s needed, has been around for a long time. It already accounts for 97 percent of energy storage worldwide and is the technology that has led to the Federal Government''s enthusiasm for a "Snowy 2.0" scheme.
