The Torus Flywheel uses electricity from the grid or a renewable energy source, like solar panels or wind turbines, to spin a heavy metal disc using its motor-generator, storing kinetic energy. This kinetic energy is later converted back into electricity for businesses and utility providers to use as the disc gradually slows down.
For a given energy storage capacity, there is a trade-off between power and discharge time. Both need to be adequate to do the job. A small steel flywheel system with several seconds of ride-through capability can be used to augment a battery system, and reduces the number of discharge cycles on the batteries, which extends their useful life.
