Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10, up to 10, cycles of use), high specific energy (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The energy efficiency (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 kWh to 13
Enter flywheel energy storage systems (FESS), the silent workhorse that''s been quietly revolutionizing how we store power. From stabilizing New York City''s subway system to
The system consists of a 40-foot container with 28 flywheel storage units, electronics enclosure, 750 V DC-circuitry, cooling, and a vacuum system. Costs for grid inverter, energy
