SPIN (Accelerator)

Company Description: SPIN will disrupt the market for grid-scale electricity storage by delivering high efficiency flywheels with significantly lower life-cycle costs than Li-ion and other batteries. Revolution is a 30kWh/6kW high-speed carbon fiber flywheel suspended in a vacuum on a zero-contact magnetic suspension. Storage capacity will not materially degrade over its planned thirty-year lifetime. The unique patented Virtual Axle spins unbalanced rotors around their natural center of inertia with no physical axle. This dramatically reduces manufacturing cost and extends the life of the system. First units available early 2019.
