A new, floating pumped hydropower system aims to cut the cost of utility-scale energy storage for wind and solar (courtesy of Sizable Energy). Support CleanTechnica's work through a Substack subscription or on Stripe. PSH complements wind and solar by storing the excess electricity they create and providing the backup for when the wind isn't blowing, and the sun isn't shining. This year's sharp U-turn in federal energy policy is a head-scratcher for any. . Pumped storage hydropower (PSH) is a type of hydroelectric energy storage.

The system also requires power as it pumps water. .
