Below are some of the paper's key messages and findings. Pumped storage hydropower (PSH), 'the world’s water battery’, accounts for over 94% of installed global energy storage capacity, and retains several advantages such as lifetime cost, levels of sustainability and scale.
Pumped storage hydropower stores energy and provides services for the electrical grid. This Review discusses the types, applications and broader effects of this form of grid-scale energy storage.
Pumped storage facilities are built to push water from a lower reservoir uphill to an elevated reservoir during times of surplus electricity. In pumping mode, electric energy is converted to potential energy and stored in the form of water at an upper elevation, which is why it is sometimes called a “water battery”.
