Flywheel Energy Storage Explained
How flywheels store kinetic energy, return it through a motor-generator and where losses and safety engineering matter.
Core principle
A flywheel stores energy as the kinetic energy of a spinning rotor. Energy must first be supplied to accelerate that rotor.
Recovering electricity
A motor-generator and power electronics can convert stored rotational energy back into electrical power. Real systems have conversion and friction losses.
Engineering matters
DOE material describes containment, bearings, vacuum or low-friction environments and power conversion as important parts of modern systems. High-speed rotating masses deserve serious safety engineering.
