First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
Energy Storage: The flywheel continues to spin at high speed, maintaining energy as long as friction and resistance are minimized. The longer it spins, the more energy it holds, similar to how the skater retains rotational energy as they keep spinning.
Flywheel Systems are more suited for applications that require rapid energy bursts, such as power grid stabilization, frequency regulation, and backup power for critical infrastructure. Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage.
The laws of physics (explained briefly in the box below—but you can skip them if you're not interested or you know about them already) tell us that large diameter and heavy wheels store more energy than smaller and lighter wheels, while flywheels that spin faster store much more energy than ones that spin slower.
This energy can be discharged continuously without being interfered because the energy is stored mechanically and not chemically. As the flywheel discharges, the flywheel's rotor speed gets slower and the stored energy decreases. The schematic diagrams of FESS and wind turbine are illustrated as in Fig. 4 [40,53,57,58].
High Efficiency: Flywheel systems are highly efficient at storing and releasing energy, with minimal energy loss over time. Environmentally Friendly: Since there are no harmful chemicals or heavy metals involved, flywheels are considered a greener option compared to chemical batteries.
