Flywheel energy storage (FES) works by spinning a rotor () and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of the flywheel.

Energy storage is crucial to the worldwide energy shift for power grid integration of renewable sources. Storage systems stabilize the grid with lower wind and solar intermittency. We need additional capacity to store the energy generated from wind and solar power for periods when there is less wind and sun. For instance, battery energy storage systems can balance supply and demand while absorbing surplus energy during peak. .
