Flywheels are one of the world’s oldest forms of energy storage, but they could also be the future. This article examines flywheel technology, its benefits, and the research from Graz University of Technology. Energy storage has risen to prominence in the past decade as technologies like renewable energy and electric vehicles have emerged.
Electric vehicles are typical representatives of new energy vehicle technology applications, which are developing rapidly and the market is huge. Flywheel energy storage systems can be mainly used in the field of electric vehicle charging stations and on-board flywheels.
Flywheel batteries are probably the most compact energy storage systems that can be designed with the lowest environmental impact and highest durability. Not quite domestic, but the technology keeps maturing. It's better suited for leveling short-lived and massive power needs rather than storing energy for days (note the 7%/hr loss below).
The minimum speed of the flywheel is typically half its full speed, the storage energy is be given by ½ (12-0.52) Ifwf2 where If is the rotor moment of inertia in kgm2 and the wf maximum rotational speed in rad/s. The power level is controlled by the size of the M/G, so this is independent of the rotor.
Recently, a team of researchers led by TU Graz announced the successful development of a flywheel prototype that can store electricity and provide fast charging outputs. The new prototype, FlyGrid, is a flywheel storage system integrated into a fully automated fast-charging station, allowing it to be a solution for fast EV charging stations.
Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Energy storage flywheels are usually supported by active magnetic bearing (AMB) systems to avoid friction loss. Therefore, it can store energy at high efficiency over a long duration. Although it was estimated in [3] that after 2030, li-ion batteries would be more cost-competitive than any alternative for most applications.

TL;DR - Because of how flywheel energy storage scales it is unlikely that significant efforts will be made to develop the technology for home use. This is similar to the case for windmills, where the power output increases as the square of the diameter, and the cube of the wind speed (which itself doubles roughly every 20m of elevation).

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th…
