What is a flywheel energy storage system?

Flywheel energy storage systems offer a unique and efficient alternative to traditional battery systems, with advantages in speed, lifespan, and environmental impact. While battery storage remains the dominant choice for long-term energy storage, flywheel systems are well-suited for applications requiring rapid energy release and frequent cycling.

What is the difference between a flywheel and a battery storage system?

Flywheel Systems are more suited for applications that require rapid energy bursts, such as power grid stabilization, frequency regulation, and backup power for critical infrastructure. Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage.

How does a flywheel system store electricity?

A flywheel system is able to store electricity by converting it into kinetic energy using a motor to spin a rotor. The flywheel rotates at such a high speed that the electrical power is transformed into mechanical power.

Why should you use a flywheel for solar power?

Moreover, flywheels can store and release energy with minimal losses, particularly when used for short-duration storage (on the order of minutes to a few hours). This makes them ideal for solar power applications where energy needs to be stored during the day and discharged in the evening.

Can a 10 kWh flywheel store electricity from a residential solar array?

With a surface of about 10 square metres, the 10 kWh flywheel can be used to store electricity from a residential solar array. Image: Energiestro From pv magazine France France-based start-up Energiestro has developed a storage technology for residential PV based on a flywheel system based on concrete.

What is flywheel technology?

Flywheel technology is a method of energy storage that uses the principles of rotational kinetic energy. A flywheel is a mechanical device that stores energy by spinning a rotor at very high speeds.
