Typically, the energy input to a Flywheel Energy Storage System (FESS) comes from an electrical source like the grid or any other electrical source.
How does a flywheel work?
For a flywheel, this depends on both the amount of mass it has and how that mass is spread out around its spinning axis. If you add more mass to the flywheel, you increase its moment of inertia. This means the flywheel can store more energy at the same speed. So, a heavier flywheel can hold more energy and deliver more power when needed.
Are flywheels a good investment?
Flywheels boast several qualities that make them handy for various applications: They have a high power density, meaning they can release a lot of energy in a small space. They also have a high energy density, packing a punch in terms of the amount of energy they can store.
