Energy storage flywheels are usually supported by active magnetic bearing (AMB) systems to avoid friction loss. Therefore, it can store energy at high efficiency over a long duration. Although it was estimated in [3] that after 2030, li-ion batteries would be more cost-competitive than any alternative for most applications.
