Pumped hydro energy storage (PHES) store energy in the form of potential energy of water that is pumped from a lower reservoir to a higher-level reservoir. In this type of system, low cost electric power (electricity in off-peak time) is used to run the pumps to raise the water from the lower reservoir to the upper one ( Rehman et al ., 2015 ).

Or, it can move through a turbine to generate electricity. When it comes to circuits and electronic devices, energy is typically stored in one of two places. The first, a battery, stores energy in chemicals. Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field.

A flywheel is a mechanical device. It rotates and stores energy. First, electrical energy is used to make it spin. The spinning creates kinetic energy. Then the electrical energy gets turned off. But because of inertia, the flywheel will keep spinning. Later, you can turn the kinetic energy back into electrical energy.

Pumped hydropower storage uses excess electricity to pump water from a lower reservoir up to a higher one (for example up a mountain or hill) where it is stored. When electricity is needed, the water is released from the higher reservoir and runs down the natural incline, passing through a typical hydro-power turbine to generate electricity.

The operating principle of a battery energy storage system (BESS) is straightforward. Batteries receive electricity from the power grid, straight from the power station, or from a renewable energy source like solar panels or other energy source, and subsequently store it as current to then release it when it is needed.
