Flywheel Energy Storage Systems (FESS) play an important role in the energy storage business. Its ability to cycle and deliver high power, as well as, high power gradients makes them superior for storage applications such as frequency regulation, voltage support and power firming.
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.
This project explored flywheel energy storage R&D to reach commercial viability for utility scale energy storage. This required advancing the design, manufacturing capability, system cost, storage capacity, efficiency, reliability, safety, and system level operation of flywheel energy storage technology.
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.
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.
Flywheels have been experimentally shown to provide bus regulation and attitude control capability in a laboratory. A sizing code based on the G3 flywheel technology level was used to evaluate flywheel technology for ISS energy storage, ISS reboost, and Lunar Energy Storage with favorable results.
