A flywheel is a very simple device, storing energy in rotational momentum which can be operated as an electrical storage by incorporating a direct drive motor-generator (M/G) as shown in Figure 1. The electrical power to and from the M/G is transferred to the grid via inverter power electronics in a similar way to a battery or any other non-synchronous …
Examples of flywheels optimized for vehicular applications were found with a specific power of 5.5 kW/kg and a specific energy of 3.5 Wh/kg. Another flywheel system had 3.15 kW/kg and 6.4 Wh/kg, which can be compared to a state-of-the-art supercapacitor vehicular system with 1.7 kW/kg and 2.3 Wh/kg, respectively.
