Flywheel energy storage (FES) works by spinning a rotor () and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of the flywheel.

What is a flywheel energy storage system?
A typical system consists of a flywheel supported by rolling-element bearing connected to a motor–generator. The flywheel and sometimes motor–generator may be enclosed in a vacuum chamber to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings.
What are the benefits of a flywheel system?
2. Renewable Energy Integration These systems are particularly effective for integrating renewable energy sources, such as wind and solar. Flywheels can store excess energy generated during peak production times and release it when generation is low, ensuring a consistent energy supply.
Who makes flywheel energy storage systems (fess)?
Amber Kinetics manufactures flywheel energy storage systems (FESS). Long-duration flywheels results in safe, economical and reliable energy storage. Elytt Energy
What is a 20 megawatt flywheel energy storage system?
The 20-megawatt system marks a milestone in flywheel energy storage technology, as similar systems have only been applied in testing and small-scale applications. The system utilizes 200 carbon fiber flywheels levitated in a vacuum chamber. The flywheels absorb grid energy and can steadily discharge 1-megawatt of electricity for 15 minutes.
For consumers, energy storage provides backup power during outages, lowers energy bills by storing excess solar power for use when solar panels aren't generating, and increases energy independence by reducing reliance on the grid. . Energy storage is critical to America's energy security, abundance and dominance in 2025 and beyond. The steadily rising need for electricity is driven by overall economic growth, AI development and new data centers, aging infrastructure and weather-related grid disruptions. Energy storage also. . At its core, energy storage encompasses a diverse set of technologies designed to absorb electricity during periods of excess generation and discharge it when demand exceeds supply. These systems play a critical role in enhancing grid flexibility, improving reliability and supporting the. .
