Flywheel Energy Storage: A High-Efficiency
Flywheel energy storage is an exciting solution for efficient and sustainable energy management. This innovative technology offers high
A flywheel energy storage system works by applying a torque in the direction of rotation to speed up the rotor, and applying a torque in the reverse direction to slow it down. On one level, it is simple to implement and understand in comparison with many other energy storage methods, and can store and release energy for potentially unlimited cycles.
As more energy is imparted into a flywheel it speeds up as it stores more energy and slows down when it loses the said energy, . Although, the existing lithium-ion battery has a high energy density but high cost in term of power capacity and less power density.
The energy stored in a vehicle-mounted flywheel system is typically low, being of similar magnitude to the kinetic energy of the vehicle operating at a moderate speed.
A flywheel stores energy by rotating a mass, or rotor, about a fixed axis. The energy stored in the flywheel rises when the angular speed of the rotor is increased and reduces when it is slowed down. The maximum energy is usually limited by the maximum angular speed, itself limited by structural considerations.
The most common configuration for flywheel energy storage is a hermetically sealed system incorporating a motor generator, as explained in Section 1 (Fig. 11.1).
The flywheel energy storage operating principle has many parallels with conventional battery-based energy storage. Connecting the rotating element to any type of shaft, it's possible to draw rotational energy from the flywheel: we are discharging the flywheel.
