Customer ServiceFlywheel energy storage (FES) can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand. The first real breakthrough of FES was the seminal book by Dr. A. Stodola in which flywheel rotor shapes and rotational stress were analyzed .
The main components of a flywheel energy storage system are a rotor, an electrical motor/generator, bearings, a PCS (bi-directional converter), a vacuum pump, and a vacuum chamber . During charging, the rotor is accelerated to a high speed using the electrical motor.
Environmental and energy performance indicators are an important part of the investment decisions prior to the deployment of utility-scale flywheel energy storage systems. There are no published studies on the environmental footprints of FESSs that investigate all the life cycle stages from cradle-to-grave.
The amount of energy stored, E, is proportional to the mass of the flywheel and to the square of its angular velocity. It is calculated by means of the equation (1) E = 1 2 I ω 2 where I is the moment of inertia of the flywheel and ω is the angular velocity.
The development and commercialization of composite materials are crucial in reducing the overall system cost. Research is being conducted to reduce friction loss and improve the discharge duration of flywheels. Amber Kinetics developed a FESS that can discharge for 4 h which will allow it to be used for energy applications . 3.3.
The net energy ratios of steel and composite flywheels are 2.5–3.5 and 2.7–3.8. The GHG emissions of steel and composite flywheels are 75–121 and 49–95 kg CO 2 eq/MWh. Flywheel energy storage systems are feasible for short-duration applications, which are crucial for the reliability of an electrical grid with large renewable energy penetration.
