6 FAQs about [Basic price of flywheel energy storage power generation]

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 much does a flywheel power converter cost?

The costs of a power converter for composite and steel flywheels are $49,618 and $52,595, respectively. The cost difference is due to the difference in rated power, 100 kW for the composite flywheel and 108 kW for the steel flywheel. Fig. 5. Equipment cost distribution for the flywheel energy storage systems.

How much does a steel rotor flywheel cost?

The steel rotor flywheel has a lower capital cost and levelized cost of storage. The costs of composite and steel rotor flywheels are $190 and $146/MWh, respectively. Flywheel energy storage systems are increasingly being considered as a promising alternative to electro-chemical batteries for short-duration utility applications.

Why are flywheel energy storage systems made with high-strength steel?

From a cost perspective, flywheel energy storage systems made with high-strength steels are ideal for maximizing energy per dollar spent. High-strength steel flywheels offer high energy density (energy per volume) because of their high mass density. Additionally, they outperform composite materials in terms of thermal conductivity and availability.

What is the power rating of a flywheel energy storage system?

Utility-scale energy storage systems for stationary applications typically have power ratings of 1 MW or more . The largest flywheel energy storage is in New York, USA by Beacon Power with a power rating of 20 MW and 15 min discharge duration .

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.
