Technical FAQs 4

How does a flywheel energy storage system work?

Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.

What is a flywheel energy storage system (fess)?

Flywheel energy storage systems (FESS) use electric energy input which is stored in the form of kinetic energy. Kinetic energy can be described as “energy of motion,” in this case the motion of a spinning mass, called a rotor. The rotor spins in a nearly frictionless enclosure.

How much energy can a flywheel store?

The small energy storage composite flywheel of American company Powerthu can operate at 53000 rpm and store 0.53 kWh of energy . The superconducting flywheel energy storage system developed by the Japan Railway Technology Research Institute has a rotational speed of 6000 rpm and a single unit energy storage capacity of 100 kW·h.

What is a flywheel energy storage unit?

The German company Piller has launched a flywheel energy storage unit for dynamic UPS power systems, with a power of 3 MW and energy storage of 60 MJ. It uses a high-quality metal flywheel and a high-power synchronous excitation motor.
