QuinteQ flywheel

Technology information

By deploying the QuinteQ flywheel, high power peaks and troughs can be accommodated on a short- and long-term basis. That means a complete megawatt can be delivered in seconds. In peaks between seconds and an hour, this is a new promising technology. The system is made of lighter materials, which means it can be built compactly and deployed in containers. This makes the flywheel easy to transport to another location. It has magnetic bearings, so there is no wear on the axis of the rotating wheel. This gives virtually no losses. Because the flywheel can deliver and absorb power peaks in locations where it is difficult to do grid expansion or install a permanent, large-scale solution, it gives the industry flexibility.

For whom interesting

  • Owners and operators of fast charging plazas of electric buses, trucks with larger grid connection.
  • Trams, metro and trains for brake energy capture and peakshaving.
  • Business parks or residential areas with own generation and microgrid that need grid stabilisation and peak shaving.
  • Operators of tower cranes, cranes at ports looking to recover energy and peak port.
  • Traders in energy who want to supply larger capacities quickly especially in imbalance market.

Advantages and disadvantages

  • 350,000 cycles
    The flywheel floats in a magnetic field based on a superconducting crystal. This results in less wear and tear, making the technology last longer.
  • Compact & robust
    The flywheel is made of lightweight material, allowing the flywheel to be used in transportable containers.
  • Innovative
    This technology is based on dozens of Boeing patents licensed to QuinteQ worldwide.
  • Economic
    Because of the above, the flyweed offers extremely low energy storage costs of: €0.03 per Kilowatt hour Levelised cost of storage (LCOS).
  • Circular
    All materials are widely available and fully recyclable.
  • Specifically for high capacities that need to be delivered or stored quickly.
  • Relatively less capacity
Specifications
  • Cycles The flywheel offers over 350,000 cycles, making it both an economical and sustainable alternative to 2018 and regular 2019 battery systems.
  • Material The flywheel is made of carbon, rather than metal. This offers the possibility of a smaller and handier model, allowing the flywheel to be used in transportable containers.
  • Size The modular arrangement makes scaling up the system relatively easy.
  • Cost €0.03 per Kilowatt hour Levelised cost of storage (LCOS).
  • Maintenance The flywheel floats in a magnetic field based on a superconducting crystal. This results in less wear and tear, making the technology last longer.
  • Temperature Robust technology that stands up well to colder and warmer environments.
