Customer ServiceA flywheel energy storage system (FESS) uses a high speed spinning mass (rotor) to store kinetic energy. The energy is input or output by a dual-direction motor/generator. To maintain it in a high efficiency, the flywheel works within a vacuum chamber.
Flywheel Energy Storage Systems (FESS) are found in a variety of applications ranging from grid-connected energy management to uninterruptible power supplies. With the progress of technology, there is fast renovation involved in FESS application.
The flywheel module, shown in Fig. 1, is designed to store a total of 1.25 kWh at 36,000 rpm and deliver 160kW (200 kVA) for more than 18 seconds, or 300kw for 5 seconds. In many flywheel designs that have been suggested, the goal of maximizing energy density has lead to carbon fiber composites as the material choice for the flywheel hub.
A 30 MW flywheel grid system started operating in China in 2024. Flywheels may be used to store energy generated by wind turbines during off-peak periods or during high wind speeds. In 2010, Beacon Power began testing of their Smart Energy 25 (Gen 4) flywheel energy storage system at a wind farm in Tehachapi, California.
One such application is the charging of the flywheel through the energy dissipated in the deceleration of a cargo container as it is being lowered by a gantry crane and discharging the captured energy in the acceleration of the container as it is subsequently lifted.
The flywheel based storage system is targeted for some applications where the characteristics of flywheels offer advantages over chemical batteries: 1) ride-through power in turbine or diesel generator sets, 2) voltage support in rail applications, 3) power quality improvement, and 4) uninterruptible power supplies (UPS).
