Flywheel energy storage systems. Energy storage is becoming increasingly important with the rising need to accommodate the energy needs of a greater population. Energy storage is especially important with intermittent sources such as solar and wind. A typical flywheel system is comprised of an energy storage rotor, a motor-generator system
A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical inputs spin the flywheel rotor and keep it spinning until called upon to release the stored energy. The amount of energy available and its duration is controlled by the mass and speed of the flywheel.
To recover the energy the motor was electrically reversed and used as a generator to slow down the flywheel converting the mechanical energy back into electrical energy.
