Technical FAQs 4

What is a flywheel energy storage system?

Fig. 1 has been produced to illustrate the flywheel energy storage system, including its sub-components and the related technologies. A FESS consists of several key components: (1) A rotor/flywheel for storing the kinetic energy. (2) A bearing system to support the ro-tor/flywheel.

What is a flywheel standard?

The standard is designed in accordance with domestic and international flywheel standard conventions, while also referencing related electrochemical energy storage system standards.

What is China's first group standard for flywheel energy storage systems?

On April 10, 2020, the China Energy Storage Alliance released China’s first group standard for flywheel energy storage systems, T/CNESA 1202-2020 “General technical requirements for flywheel energy storage systems.”

When will flywheel energy storage standards be released?

The group agreed that the standard should be released as soon as possible, and recommended further improvements of standards to support flywheel energy storage systems. Following final approval by the Alliance Standards Committee, CNESA officially released the standard on April 10, 2020.
