How does a Flywheel energy storage system work?

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. This is a common method for energy storage.

How does a flywheel create kinetic energy?

To create kinetic energy, the motor derives energy from the electric grid to power the cylinder or disk to spin at a rate of up to 60,000 RPM. Because a flywheel must be accelerated by an external force before it will store energy, it is considered a “dynamic” storage system.

How much energy does a flywheel use?

The flywheel in an all-electric propulsion system is assumed to have an energy storage capacity of 0.5 kWh and weigh 35 kg. It is assumed to use 75% of its total energy stored, which implies a practical speed range of half the total speed range (from half the maximum speed to the maximum speed).

How much does a flywheel energy storage system cost?

The cost of a flywheel energy storage system is $6,000. Each kilowatt is priced at $1,333 a kilowatt. This flywheel energy storage design is a viable electricity source in homes. It functions to meet peak power demands within 25 seconds, allowing for significant savings in energy costs.

How does a flywheel accumulate power?

The level of power trapped in a flywheel is proportional to the square of its rotational movement. Energy is delivered to a flywheel by the utilization of a torsional power to it, consequently raising its rotational velocity, and as a result its accumulated power.

Why is a flywheel considered a dynamic storage system?

Because a flywheel must be accelerated by an external force before it will store energy, it is considered a “dynamic” storage system. The rate at which the flywheel spins remains nearly constant because of the vacuum-like container, which prevents friction from slowing the revolution.
