Flywheels store the energy created by turning an internal rotor at high speeds-slowing the rotor releases the energy back to the grid when needed. Beacon Power is redesigning the heart of the flywheel, eliminating the cumbersome hub and shaft typically found at its center. When excess electricity is available, it is used to accelerate a flywheel to a very high speed. The energy is stored as kinetic energy and can be retrieved by slowing down the flywheel. . Flywheel energy storage is a mechanical energy storage technology that has gained significant attention in recent years due to its potential to enhance the efficiency and reliability of renewable energy systems.
