6 FAQs about Canadian flywheel energy storage

What is the Clear Creek flywheel energy storage system?

The Clear Creek Flywheel Energy Storage System is a 5,000kW energy storage project located in Norfolk County, Ontario, Canada. The electro-mechanical energy storage project uses flywheel as its storage technology. The project was announced in 2013 and was commissioned in 2016.

What is a flywheel energy storage system?

Flywheel energy storage systems utilize fast-spinning machines to very quickly inject or absorb reactive and non-reactive power to/from the grid. The fast ramping of these systems can potentially impact the operating conditions of existing power delivery networks thereby requiring a Detailed Connection Impact Assessment (DCIA).

Does a flywheel energy storage system affect the environment?

Flywheel energy storage system use is increasing, which has encouraged research in design improvement, performance optimization, and cost analysis. However, the system's environmental impacts for utility applications have not been widely studied.

Does Guelph Hydro need a flywheel energy storage system?

Guelph Hydro needed to connect a Flywheel Energy Storage System (FESS) at their Arlen Transformer Station (TS). The system would be comprised of ten 500 kW, 480V energy storage flywheels with the ability to inject and store up to 5.0 MW of electrical power to Guelph Hydro's 13.8 kV distribution system.

How much energy does a flywheel produce?

The net energy ratios of steel and composite flywheels are 2.5–3.5 and 2.7–3.8. The GHG emissions of steel and composite flywheels are 75–121 and 49–95 kg CO 2 eq/MWh. Flywheel energy storage systems are feasible for short-duration applications, which are crucial for the reliability of an electrical grid with large renewable energy penetration.

How can a composite flywheel be used for energy applications?

The development and commercialization of composite materials are crucial in reducing the overall system cost. Research is being conducted to reduce friction loss and improve the discharge duration of flywheels. Amber Kinetics developed a FESS that can discharge for 4 h which will allow it to be used for energy applications . 3.3.
