Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.
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.
Energy input: The system starts with an external power source. This can be from the grid, a renewable source, or any other form of electricity. This energy is used to set the flywheel in motion. Energy storage: As the flywheel spins, it stores kinetic energy. The energy can be stored as long as the flywheel continues to spin.
High efficiency: FES systems are capable of high-round-trip efficiencies, often above 85%. This means a larger proportion of input energy can be effectively stored and used. Environmental friendliness: Flywheels are made from materials that are easily recyclable and do not produce harmful waste, making them a greener solution for energy storage.
