Development of the standard took two years of research and discussion between the participants. In August 2018, the China Energy Storage Alliance organized and hosted a seminar on flywheel energy storage system standardization at Tsinghua University. The seminar outlined the initial framework and scope for the flywheel energy storage standard.
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.”
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
The standard is designed in accordance with domestic and international flywheel standard conventions, while also referencing related electrochemical energy storage system standards.
Following final approval by the Alliance Standards Committee, CNESA officially released the standard on April 10, 2020. The “General technical requirements for flywheel energy storage systems” standard specifies the general requirements, performance requirements, and testing methods for flywheel energy storage systems.
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.
