Flywheel Energy Storage: An Alternative to Batteries For UPS Systems
Energy Engineering, 2005 ABSTRACT Direct current (DC) system flywheel energy storage technology can be used as a substitute for batteries to provide backup power to an uninterruptible power supply (UPS) system. Although the initial cost will usually be higher, flywheels offer a much longer life, reduced maintenance, a smaller footprint, and better reliability compared to a ...
