Water Battery Storage

What is happening? Swiss scientists have built a water based battery storage system deep in the Alps. Meet Nant de Drance, located between two reservoirs in a cave 600 meters (nearly 2,000 feet) underground in the Swiss canton of Valais. It is rated power of 900 megawatts and a storage capacity of 20,000 megawatt hours.

Why is this important? By 2030, Europe needs  200 gigawatts of energy storage capacity
