What are Flywheel Energy Storage Systems?

Flywheel Energy Storage Systems are interesting solutions for energy storage, featuring advantageous characteristics when compared to other technologies. Research focuses on cost aspects, system reliability, and energy density improvement for these systems. In this context, a novel shaftless outer-rotor layout is proposed.

Can flywheel energy storage be commercially viable?

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.

What is flywheel technology?

Flywheel technology is a method of energy storage that uses the principles of rotational kinetic energy. A flywheel is a mechanical device that stores energy by spinning a rotor at very high speeds.

What is rotorvault flywheel storage?

RotorVault flywheel storage systems provide reliable energy storage solutions for residential, commercial and grid-scale applications worldwide.

How does a flywheel work?

The optimized shape spreads centripetal stress evenly throughout the entire flywheel during operation, so all of the material in the flywheel is put to use and the spin speed can be maximized. This flywheel, when paired to a motor/generator unit, behaves like a battery and energy can be stored for hours and dispatched on demand.

How long does a flywheel last?

This flywheel, when paired to a motor/generator unit, behaves like a battery and energy can be stored for hours and dispatched on demand. The system service life is 20 years, without limits to depth of discharge, charge cycles, or sensitivity to temperature extremes, using recyclable materials.
