What is a flywheel energy storage system?
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.
How do fly wheels store energy?
Fly wheels store energy in mechanical rotational energy to be then converted into the required power form when required. Energy storage is a vital component of any power system, as the stored energy can be used to offset inconsistencies in the power delivery system.
How will flywheel energy storage help the US Marines?
The US Marine Corps are researching the integration of flywheel energy storage systems to supply power to their base stations through renewable energy sources. This will reduce the dependence on chemical batteries and, ultimately cost of running . 7. Future Trends
