Can flywheel energy storage improve energy supply reliability?

The use of flywheel energy storage provides another backup alternative to improve the energy supply reliability. The storage systems store mechanical energy in a rotating flywheel that converts into electrical energy using an electrical machine and vice versa (Sebastian et al, 2012).

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 is a flywheel storage system?

In the other storage system, flywheel battery, in the strong wind or high sunlight intensity, the wind and solar machines changes the power into a mechanical flywheel energy to store up, while in the absence of the wind and sunlight, the role to supply power is switched to the flywheel storage.

Why do we need a flywheel for solar energy storage?

Several studies showed that the energy storage based on the flywheel provides the low cost of energy and carbon-dioxide emission, resolves the incapability of solar energy supply at night and the delays of the time of supply, and improves the quality and the reliability of power supply.

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.
