Which to Choose—Flywheel vs. Battery UPS?
A flywheel system has a significantly higher initial capital cost than a battery UPS. If the facility determines that batteries are also needed in addition to the flywheel in order to increase runtime, the lifecycle cost of a flywheel system will exceed the total cost of a battery system. Even if batteries are not needed, the flywheel will need

Flywheel Energy Storage
Flywheel Energy Storage (FES) is a relatively new concept that is being used to overcome the limitations of intermittent energy supplies, such as Solar PV or Wind Turbines that do not produce electricity 24/7. A flywheel energy storage system can be described as a mechanical battery, in that it does not create electricity, it simply converts
Flywheel vs. Battery UPS
For comparable installed cost, a flywheel will provide about 15 seconds of reserve energy at full UPS output load, while a storage battery will provide at least 10 minutes. Given 15 seconds of flywheel reserve energy, the UPS capacity must be limited to what one standby generator can supply."
