New Energy Storage-Flywheel Energy Storage Industry Status

At present, flywheel energy storage has many difficulties that limit its development. Flywheel energy storage cost is high, the need to develop an economical and durable rotor; flywheel energy storage energy release time is short, and the energy will be lost in dozens of hours; as the flywheel has been in the high-speed - low-speed changes, resulting in excessive stress may lead to tearing, resulting in safety issues; and so on.
