flywheel energy storage safety risk assessment

Can flywheel energy storage be commercially viable?

This project explored flywheel energy storage R&D to reach commercial viability for utility scale energy storage. This required advancing the design, manufacturing capability, system cost, storage capacity, efficiency, reliability, safety, and system level operation of flywheel energy storage technology.

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 flywheels safe?

The safety design criteria were validated though a series of induced failures and overstress events. The flywheels were completely tolerant of a number of fault scenarios such as a loss of vacuum, loss of power, and overspeed; they survived these types of events without damage and were easily put back into service.

What are the advantages of flywheel technology?

One of the advantages of flywheel technology is the environmental tolerance; chemical batteries perform poorly outside of a limited temperature range which often necessitates axillary heating and cooling systems that reduce system power conversion efficiency.

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.
