Pumped storage is by far the largest-capacity form of grid energy storage available, and, as of 2020, accounts for around 95% of all active storage installations worldwide, with a total installed throughput capacity of over 181 GW and a total installed storage capacity of over 1.6 TWh.
Pumped storage hydroelectricity is a form of energy storage using the gravitational potential energy of water. Storing the energy is achieved by pumping water from a reservoir at a lower elevation to a reservoir at a higher elevation.
Pumped-storage power plants store electricity using water from dams. The new model for using the plants in combination with renewable energy has led to a revival of the technology. In 2000, there were around 30 pumped storage power plants with a capacity of more than 1,000 megawatts worldwide.
In the event of a power outage, a pumped storage plant can reactivate the grid by harnessing the energy produced by sending "emergency" water – which is kept in the upper reservoir for this very purpose – through the turbines. Pumped storage hydropower plants fall into two categories:
Pumped Thermal Electricity Storage or Pumped Heat Energy Storage is the last in-developing storage technology suitable for large-scale ES applications. PTES is based on a high temperature heat pump cycle, which transforms the off-peak electricity into thermal energy and stores it inside two man-made thermally isolated vessels: one hot and one cold.
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 elevations.
