How many communication base stations in Northern Europe have flywheel energy storage

The flywheel is modular and offers unparalleled configurability in terms of power to energy ratio, which makes it the first dynamic energy storage system whose discharge duration can be matched exactly to the customer's needs.

The EU-27 has deployed around ten 5G base stations per million capita, whereas South Korea has rolled out around 1,500 base stations per million (by the end of 2019). The EU-27 has upgraded 1% of 4G base stations to 5G, whereas South Korea upgraded 98% (by the end of 2019).

The principle of flywheel energy storage FESS technology originates from aerospace technology. Its working principle is based on the use of electricity as the driving force to drive the flywheel to rotate at a high speed and store electrical energy in the form of mechanical energy.

Boeing has developed a 5 kW h/3 kW small superconducting maglev flywheel energy storage test device. SMB is used to suspend the 600 kg rotor of the 5 kWh/250 kW FESS, but its stability is insufficient in the experiment, and damping needs to be increased .

The power system delivers electrical energy to the flywheel device. Discharge: The process converts the mechanical energy consumed by the rotation of the flywheel into electrical energy and transmits it out, the drive motor operates as a generator, and the speed of the flywheel will decrease accordingly.

The performance of flywheel energy storage systems is closely related to their ontology rotor materials. With the in-depth study of composite materials, it is found that composite materials have high specific strength and long service life, which are very suitable for the manufacture of flywheel rotors.
