About Photovoltaic Energy StorageFlywheel energy storage (FES) can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand. The first real breakthrough of FES was the seminal book by Dr. A. Stodola in which flywheel rotor shapes and rotational stress were analyzed [7] .
About Photovoltaic Energy StorageA flywheel energy storage system can be described as a mechanical battery, in that it does not create electricity, it simply converts and stores the energy as kinetic energy until it is needed. In a matter of seconds, the electricity can be created from the spinning flywheel making it the ideal solution to help regulate supply in the electrical grid.

About Photovoltaic Energy StorageThe 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.
