How Pumped Storage Hydropower Works

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. As demonstrated in the animation, water is pumped from the lower reservoir to the upper reservoir in times of high electricity

Journal of Energy Storage

During charging, the air in the water storage vessel and air cavern is compressed by the pumped water. Subsequently, compressors 1 and 2 compress the air into the two tanks for energy storage. During discharging, the compressed air expands and successively transfers the pressure energy to the hydraulic turbine and expander for power generation.

NHA Unveils New 2021 U.S. Pumped Storage Hydropower Report

Washington, D.C. (9/22/21) – On World Energy Storage Day, the National Hydropower Association (NHA) today released the 2021 Pumped Storage Report, a comprehensive review of the U.S. pumped storage hydropower industry.
