What is China's largest flywheel energy storage plant?
China's massive 30-megawatt (MW) flywheel energy storage plant, the Dinglun power station, is now connected to the grid, making it the largest operational flywheel energy storage facility ever built.
How do flywheels store energy?
Flywheels are an ingenious way to store energy. Essentially, a giant rotor is levitated and spun in a chamber by way of magnets. Since there is very little friction, the flywheel spins continually with very little added energy input needed. Energy can then be drawn from the system on command by tapping into the spinning rotor as a generator.
How do flywheels work?
The flywheels absorb grid energy and can steadily discharge 1-megawatt of electricity for 15 minutes. The system takes the place of supplemental natural gas power plants that have been used to balance supply and demand in grid activity prior, boosting energy production during peak demand, and lowering production during peak supply.
