Energy and environmental footprints of flywheels for utility
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.
The Status and Future of Flywheel 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. This article describes the major

So doubling mass doubles energy storage, but doubling the rotational speed quadruples energy storage. Thus, it makes sense to use less mass to create a lighter, more compact footprint, but make the material stronger and safer

A typical system consists of a flywheel supported by rolling-element bearing connected to a motor–generator. The flywheel and sometimes motor–generator may be enclosed in a vacuum chamber to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors
How do flywheels store energy?
↑ This is a conservative estimate based on carbon fiber composites being typically 4–5 times lighter than steel, according to many sources. ↑ There''s a review of flywheel materials in Materials for Advanced
