What is a flywheel energy storage system (fess)?

Flywheel Energy Storage Systems (FESS) play an important role in the energy storage business. Its ability to cycle and deliver high power, as well as, high power gradients makes them superior for storage applications such as frequency regulation, voltage support and power firming.

What makes a safe flywheel system?

Robust system design, in combination with the use of certified critical materials, relevant quality control measures and documentation, are the basis for the construction of safe flywheel systems. These can be certified by appropriate independent parties as in the manufacture of many other products.

Are stornetic flywheels safe if a rotor burst?

In addition to the Sandia guidelines (4), Stornetic also believes that flywheels up to a certain energy content can be contained and mounted safely even in the event of a severe rotor burst. These designs offer additional safety opportunities to those of the Sandia recommendations.

What are the standards for flywheel rotors?

A summary of these standards can be found in . Nowadays, standards regarding flywheels are also established, such as the international standard "ISO 21648:2008 Space system-Flywheel module design and testing" and the American standard "AIAA S-096-2004 Space system-Flywheel rotor assemblies".

What challenges do flywheel producers face?
