Flywheel Energy Storage Systems (FESS)
Flywheel energy storage systems (FESS) use electric energy input which is stored in the form of kinetic energy. Kinetic energy can be described as “energy of motion,” in this case the motion
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.
Flywheel Systems are more suited for applications that require rapid energy bursts, such as power grid stabilization, frequency regulation, and backup power for critical infrastructure. Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage.
Here's a breakdown of the process: Energy Absorption: When there's surplus electricity, such as when the grid is overproducing energy, the system uses that excess power to accelerate the flywheel. This energy is stored as kinetic energy, much like how the figure skater speeds up their spin by pulling in their arms.
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.
Flywheel energy storages are commercially available (TRL 9) but have not yet experienced large-scale commercialisation due to their cost disadvantages in comparison with battery storages (higher investment, lower energy density). Another challenge is the comparably high standby loss in FESS caused by the magnetic drag of the motor-generator.
Long Lifespan: With no chemical reactions involved, flywheels can last for tens of thousands of cycles, significantly outperforming batteries in terms of longevity. High Efficiency: Flywheel systems are highly efficient at storing and releasing energy, with minimal energy loss over time.
