Closed-loop pumped storage hydropower systems connect two reservoirs without flowing water features via a tunnel, using a turbine/pump and generator/motor to move water and create electricity. The system also requires power as it pumps water. . Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. 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 report provides an analysis of PSH's evolution and technological advancements and suggests strategic actions to overcome existing barriers. . NLR experts are developing tools and partnering with industry to unlock the full potential of pumped storage hydropower (PSH)—a form of hydropower used to generate electricity, store energy, and provide grid services.
