What is a flywheel energy storage system?
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
What type of rotor does a flywheel use?
While some systems use low mass/high speed rotors, other use very massive rotors eg 200 tonnes and correspondingly much lower rotational speeds, referred to as grid-scale flywheel energy storage .
What is rotorvault's flywheel system for grid-scale energy storage?

Can HTSC powder be used for flywheel energy storage?
Since flux pinning is an important factor for providing the stabilizing and lifting force, the HTSC can be made much more easily for flywheel energy storage than for other uses. HTSC powders can be formed into arbitrary shapes so long as flux pinning is strong.
