Image: Shenzen Energy Group. A project in China, claimed as the largest flywheel energy storage system in the world, has been connected to the grid. The first flywheel unit of the Dinglun Flywheel Energy Storage Power Station in Changzhi City, Shanxi Province, was connected by project owner Shenzen Energy Group recently.

📌

Are flywheel energy storage systems a good alternative to electro-chemical batteries?

Electro-chemical ESSs can be used in short-duration services , , but they suffer from a short lifetime and the need to dispose of toxic materials , . Flywheel energy storage systems (FESSs) are a promising alternative to electro-chemical batteries for short-duration support to the grid .

📌

How much does a flywheel power converter cost?

The costs of a power converter for composite and steel flywheels are $49,618 and $52,595, respectively. The cost difference is due to the difference in rated power, 100 kW for the composite flywheel and 108 kW for the steel flywheel. Fig. 5. Equipment cost distribution for the flywheel energy storage systems.
