6 FAQs about [Mobile flywheel energy storage tram]

Why should you use flywheel storage in a tram?

Flywheel storage has proven to be useful in trams. During braking (such as when arriving at a station), high energy peaks are found which can not be always fed back into the power grid due to the potential danger of overloading the system.

What is a flywheel-storage power system?

What is a flywheel energy storage system?

The spinning speed of modern flywheel energy storage system can reach up to 16,000 rpm with a capacity of up to 25 kWh. Flywheel have low maintenance costs, and their life-span can be long. There is no greenhouse emission or toxic material produced when flywheels are working, so it is very environment-friendly.

What is a flywheel storage power plant?

In Ontario, Canada, Temporal Power Ltd. has operated a flywheel storage power plant since 2014. It consists of 10 flywheels made of steel. Each flywheel weighs four tons and is 2.5 meters high. The maximum rotational speed is 11,500 rpm. The maximum power is 2 MW. The system is used for frequency regulation.

Why are flywheels used in battery storage power stations?

Sometimes battery storage power stations are built with flywheel storage power systems in order to conserve battery power. Flywheels can handle rapid fluctuations better. In vehicles small storage of power flywheels are used as an additional mechanism with batteries, to store the braking energy by regeneration.

How much energy does a flywheel storage system lose per day?

It is now (since 2013) possible to build a flywheel storage system that loses just 5 percent of the energy stored in it, per day (i.e. the self-discharge rate).
