Flywheel energy storage (FES) works by accelerating a rotor () to a very high speed and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of th. . A flywheel-storage power system uses a for energy storage, (see ) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage. Unlike common storage power plants, such as the A flywheel-storage power system uses a flywheel for energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage. [pdf]

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 (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (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 to 1. The FESS is capable of generating several mW of power for brief periods. Flywheels are best suited to produce high power outputs of 100 kW to 2 mW over a short period of 12-60 seconds. The peak output, at 125 kW for 16 seconds, is sufficient to provide 2 mW for one second. [pdf]
The flywheel goes through three stages during an operational cycle, like all types of energy storage systems: The flywheel speeds up: this is the charging process. Charging is interrupted once the flywheel reaches the maximum allowed operating speed. The flywheel energy storage system is now at capacity.
Flywheel Energy Storage Systems (FESS) are found in a variety of applications ranging from grid-connected energy management to uninterruptible power supplies. With the progress of technology, there is fast renovation involved in FESS application.
Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electrical power system into one that is fully sustainable yet low cost.
Our flywheel energy storage calculator allows you to calculate the capacity of an interesting type of battery!
Assuming a 28 in wheel with mass m = 2.87 lb, the energy stored is 3.25 J. To find this result: I = 2.87 × 1 × 14² = 3.9 lb·ft². How does a flywheel store energy? A flywheel can store energy thanks to the conservation of angular momentum.
To connect the Flywheel Energy Storage System (FESS) to an AC grid, another bi-directional converter is necessary. This converter can be single-stage (AC-DC) or double-stage (AC-DC-AC). The power electronic interface has a high power capability, high switching frequency, and high efficiency.
