New pumped hydro around the world: Tried and

For over 100 years, pumped-storage hydroelectric power (pumped hydro) has supported electricity consumption around the world. The principles of the technology are fairly simple, but ingenious: when electricity demand peaks, water falls from an upper reservoir into a lower reservoir, passing through turbines which generate power.

Pumped hydro resurfaces as a net-zero stalwart

Pumped hydro energy storage (PHES) has been in use for more than a century. It involves pumping water from a lower to an upper reservoir when there is spare power generation capacity (on windy or sunny days, for example), and letting it run down to the lower reservoir via a turbine to generate electricity when there is a shortfall – such as
