The wind turbine industry plays a crucial role in the green transition, but producing new spare parts for aging turbines requires large amounts of resources. At Momentum, we actively work to extend the lifetime of our existing wind turbines through reuse and recycling of components. This not only reduces our environmental footprint, but also ensures a more cost-efficient operation.

A concrete example of our recycling strategy is our recent purchase of a decommissioned wind turbine nacelle in France. This nacelle, which was dismantled after production was completed, we bought as a source of spare parts – including for one of our wind turbines on Bornholm, which was down due to a faulty gearbox. By reusing components from the French nacelle, we were able to bring the wind turbine back into operation without having to invest in new, energy-intensive components.

To minimize the carbon footprint of the transport, we chose to ship the nacelle to Denmark rather than transport it by truck. After transit, the nacelle arrived at our workshop in Denmark, where employees from our service company, Momentum Energy Services, received it.

From spare parts to new energy on Bornholm

In Denmark, the nacelle was inspected and the parts that would be used for the wind turbine on Bornholm were inspected and refurbished, including gears, main bearing and oil system.

By reusing the gears, main shaft and oil system from the French nacelle, we got the turbine back into production – without having to invest in newly manufactured parts.

The rest of the nacelle components have been stored in our warehouse, ready to be used when other N60 turbines need repairs.

A circular approach to wind energy

This program is a good example of how we at Momentum work to keep resources in circulation for as long as possible. Instead of depending on new, expensive components, we prioritize reuse and repair wherever possible. This not only benefits our economy and reliability, but also the climate and the environment.

By optimizing the use of existing materials, we can also extend the lifetime of our wind turbines. This is an important part of our commitment to a more sustainable future, where wind energy is not only green in production, but also operated in a greener way.
