What is a flywheel energy storage system (fess)?
The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power. Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs).
What is flywheel energy storage?
Flywheel energy storage is mostly used in hybrid systems that complement solar and wind energy by enhancing their stability and balancing the grid frequency because of their quicker response times or with high-energy density storage solutions like Li-ion batteries .
How do fly wheels store energy?
Fly wheels store energy in mechanical rotational energy to be then converted into the required power form when required. Energy storage is a vital component of any power system, as the stored energy can be used to offset inconsistencies in the power delivery system.
Why do flywheels need a strong containment vessel?
Traditional flywheel systems require strong containment vessels as a safety precaution, which increases the total mass of the device. The energy release from failure can be dampened with a gelatinous or encapsulated liquid inner housing lining, which will boil and absorb the energy of destruction.
