How Pumped Storage Hydropower Works | Department of Energy

HOW DOES PUMPED STORAGE HYDROPOWER WORK? Pumped storage hydropower (PSH) is one of the most-common and well-established types of energy storage technologies and currently accounts for 96% of all utility-scale energy storage capacity in the United States. PSH facilities store and generate electricity by moving water between two reservoirs at different

Pumped hydro storage for intermittent renewable energy

Globally, communities are converting to renewable energy because of the negative effects of fossil fuels. In 2020, renewable energy sources provided about 29% of the world''s primary energy.
