How much does a flywheel energy storage system cost?

The amortized capital costs are $130.26 and $92.01/kW-year for composite and steel rotor FESSs, respectively. The corresponding LCOSs are $189.94 and $146.41/MWh, respectively. Table 4. Cost summary for 20 MW/5MWh flywheel energy storage systems.

How does Flywheel energy storage 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.

Why are composite rotor flywheel energy storage systems more expensive?

The differences in the TIC of the two systems are due to differences in rotor and bearing costs. The composite rotor flywheel energy storage system costs more than the steel rotor flywheel energy storage system because composite materials are still in the research and development stage and material and manufacturing costs are high.

How efficient is a flywheel system?

Due to their simple design and frictionless characteristics, flywheel systems can reach very high efficiencies of 70-95%, where only a small fraction of the energy is lost during storage.

How does a flywheel work?

A flywheel operates on the principle of storing energy through its rotating mass. Think of it as a mechanical storage tool that converts electrical energy into mechanical energy for storage. This energy is stored in the form of rotational kinetic energy.

Can flywheels store more energy?

However, over the last 30 years, scientific innovation has meant that flywheels can store more energy in less weight and volume, increasing their potential for energy storage. Newer flywheels are made from very strong composite materials and are operated on a bed of near frictionless magnetic bearings housed in a vacuum enclosure.
