In this paper, state-of-the-art and future opportunities for flywheel energy storage systems are reviewed. The FESS technology is an interdisciplinary, complex subject that involves electrical, mechanical, magnetic subsystems. The different choices of subsystems and their impacts on the system performance are discussed.

A flywheel is supported by a rolling-element bearing and is coupled to a motor-generator in a typical arrangement. To reduce friction and energy waste, the flywheel and sometimes the motor–generator are encased in a vacuum chamber. A massive steel flywheel rotates on mechanical bearings in first-generation flywheel energy storage

Optimal energy systems is currently designing and manufacturing flywheel based energy storage systems that are being used to provide pulses of energy for charging high voltage capacitors in a mobile military system. These systems receive their energy from low voltage vehicle bus power (<480 VDC) and provide output power at over 10,000 VDC without the

Electric Flywheel Basics. The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to (Equation 1) E = 1 2 I ω 2 [ J], where E is the stored kinetic energy, I is the flywheel moment of inertia [kgm 2 ], and ω is the angular speed [rad/s].

Energy storage flywheels are usually supported by active magnetic bearing (AMB) systems to avoid friction loss. Therefore, it can store energy at high efficiency over a long duration. Although it was estimated in [3] that after 2030, li-ion batteries would be more cost-competitive than any alternative for most applications.

Examples of flywheels optimized for vehicular applications were found with a specific power of 5.5 kW/kg and a specific energy of 3.5 Wh/kg. Another flywheel system had 3.15 kW/kg and 6.4 Wh/kg

NASA G2 flywheel. Flywheel energy storage ( FES) works by accelerating a rotor ( flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy;

Today''s cost for advanced lithium batteries (one of the leading energy storage candidates) capable of storing 1 MWh of electricity is about $2 million, about the same capital cost per megawatt-hour as the wind turbine. So if a 1 MW-rated turbine has good wind and is able to produce its megawatt hour rating for 10 hours it will produce 10
