Storing Renewable Energy in Flywheels
Efficient storage of energy The flywheel works through a heavy cylinder that is kept floating in vacuum containers by the use of a magnetic field. By adding power to it – e.g. energy from a wind turbine – the flywheel is pushed into motion. As long as the wheel is rotating, it stores the energy that initially started it.
