Flywheel Energy Storage: The Key to Sustainable Energy …
Flywheel energy storage works by storing kinetic energy in a rotating mass. A flywheel system consists of a heavy rotating mass connected to a high-speed motor or generator. The flywheel is designed to rotate at high speed, and when electricity is supplied to the motor, the flywheel starts to spin, storing kinetic energy.
