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.
Lifespan: Flywheels tend to last much longer than batteries, especially for high-cycle applications. Suitability for Short-Term Energy Needs: Flywheels excel in managing short-term energy surges or imbalances, while batteries are often better for long-term storage. Which Is Better: Flywheel or Battery Energy Storage?
Motor/Generator: This component drives the flywheel and also converts the kinetic energy back into electricity. Bearings: Advanced bearings help reduce friction, allowing the flywheel to maintain its speed. Power Electronics: These regulate the flow of electricity in and out of the system.
A 30 MW flywheel grid system started operating in China in 2024. Flywheels may be used to store energy generated by wind turbines during off-peak periods or during high wind speeds. In 2010, Beacon Power began testing of their Smart Energy 25 (Gen 4) flywheel energy storage system at a wind farm in Tehachapi, California.
