There are a few key reasons. First, flywheels are quick to adapt to changes in power demand, so they can supply power when it is most needed. This is particularly crucial for renewable energy sources because they can be unpredictable. Second, unlike batteries, flywheels have a long lifespan and don''t lose their effectiveness over time.
A review of flywheel energy storage technology was made, with a special focus on the progress in automotive applications. We found that there are at least 26 university research groups and 27 companies contributing to flywheel technology development. Flywheels ...
The storage capacity depends on the size and rotational speed of the flywheel, the latter is more significant since the storage capacity is proportional to the square of the flywheel speed. The use of composite materials allows for faster rotational speeds and higher power densities than equivalent battery energy storage systems.
