Flywheel energy-storage systems

The company’s flywheel energy-storage systems reportedly replace 40 lead-acid batteries and respond to all power disturbances. The system uses no bearings and connects to the DC bus of a UPS. The unit has a small footprint and uses a five-point magnetic levitation system that floats and secures the spinning mass in place. No concrete pad is needed for installation. The system maintains a factory-sealed high vacuum without any mechanical pump.
