Flywheels are used as intermediate energy storage systems for transport applications such as automobiles. Flywheel storage energy systems are more commonly used in Formula 1 cars and hybrid vehicles. However, manufacturers such as Maruti Suzuki have adopted this technology for passenger vehicles also.
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
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.
