Flywheels as Batteries
A reasonable estimate for the cost of lithium ion batteries in 2018 is about $300 kWh-1, so we see that purely from a cost perspective the flywheel solution is roughly a quarter the price if we assume a flywheel system with no energy loss due to friction, Earth''s rotation, and various other sources of energy loss. [5]
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." Though flywheels cannot deliver the same length of power …

Is a Flywheel a Rechargeable Battery? Comparing Energy Storage …
Cost: The initial cost of flywheel systems is typically higher than that of conventional batteries. A report by the U.S. Department of Energy states that flywheel energy storage systems can cost around $1,000 per kWh, compared to lithium-ion batteries, which average about $400 per kWh. This higher cost can deter widespread adoption, particularly in …
