How a flywheel energy storage system works?
Thanks to the power electronics and composite material technology, the flywheel energy storage system performances are increasing. In conventional flywheel energy storage systems, a motor is connected to a rotating mass shaft and the motor performs energy storage. Energy is taken with another generator connected to the rotating mass (discharge).
How can flywheels be more competitive to batteries?
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.
How kinetic energy is stored in a flywheel?
In this storage scheme, kinetic energy is stored by spinning a disk or rotor about its axis. Amount of energy stored in disk or rotor is directly proportional to the square of the wheel speed and rotor׳s mass moment of inertia. Whenever power is required, flywheel uses the rotor inertia and converts stored kinetic energy into electricity .
Why do flywheel energy storage systems have a high speed?
There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system. The high speeds have been achieved in the rotating body with the developments in the field of composite materials.
