FAQs 6

What is a flywheel energy storage system?

A typical flywheel energy storage system , which includes a flywheel/rotor, an electric machine, bearings, and power electronics. Fig. 3. The Beacon Power Flywheel , which includes a composite rotor and an electric machine, is designed for frequency regulation.

Could flywheels be the future of energy storage?

Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electrical power system into one that is fully sustainable yet low cost.

How much energy does a flywheel store?

Indeed, the development of high strength, low-density carbon fiber composites (CFCs) in the 1970s generated renewed interest in flywheel energy storage. Based on design strengths typically used in commercial flywheels, σmax /ρ is around 600 kNm/kg for CFC, whereas for wrought flywheel steels, it is around 75 kNm/kg.

Are flywheels viable for utility-scale energy storage?

Flywheels are only viable for utility-scale energy storage when multiple units can be integrated into an array to achieve the necessary storage capacity. Developing hardware, software and a test platform is necessary to successfully demonstrate multi-unit array operation with balanced power and state of charge (SoC).

Can flywheels save energy?

Installing 100 MW’s worth of flywheels used for distribution can reduce demand charges by $36 million and provide $8 million of energy savings a year since the FESS can eliminate mid-day peak and evening peaks of electricity use. Lithium battery technology can only do one peak reduction a day.
