The flywheel energy storage is a substitute for steam-powered catapults on aircraft carriers. The use of flywheels in this application has the potential for weight reduction. The US
A flywheel energy storage system works by spinning a large, heavy wheel, called a flywheel at very high speeds. The energy is stored as rotational kinetic energy in the spinning wheel. When electricity is needed, the flywheel's rotational speed is reduced, and the stored kinetic energy is converted back into electrical power using a generator.
China has successfully connected its 1st large-scale standalone flywheel energy storage project to the grid. The project is located in the city of Changzhi in Shanxi Province. The power output of the facility is 30 MW and it is equipped with 120 high-speed magnetic levitation flywheel units.
The power system delivers electrical energy to the flywheel device. Discharge: The process converts the mechanical energy consumed by the rotation of the flywheel into electrical energy and transmits it out, the drive motor operates as a generator, and the speed of the flywheel will decrease accordingly.
The project is pioneering the use of a semi-buried underground well system. It is designed to provide a safe environment for waterproofing, cooling, operation, and maintenance of the flywheel unit. The construction of the Dinglun Flywheel Energy Storage Power Station began in July 2023.
