Sif has reached agreements with Dillinger for the supply of lower-emission steel for offshore wind foundations and to progress monopile recycling efforts.
The addendum signing to the companies’ long-term steel plate supply framework agreement aims to achieve full circularity of monopiles.
In addition to the signing of this addendum a memorandum of understanding between Sif Decom (a Sif subsidiary) and Dillinger has been signed relating to a decommissioning process for offshore wind foundations.
This MoU marks the finalisation of a joint-research project executed by Sif, KCI and Dillinger to produce a detailed design for a monopile recycling factory.
Sif Decom will now continue working to finalise the business case.
Once the investment decision is taken, Dillinger will be invited to participate in the monopile recycling factory, and in return will secure the high-grade steel output by it.
The plant is designed to close the circularity loop by providing the recycled steel as efficiently as possible for Dillinger’s low-emission steel production.
By signing the “green steel” addendum to the plate supply framework agreement, Sif and Dillinger have further detailed the transition to supplying green steel plates for Sif’s new and enhanced XXXL monopile factory.
Sif chief executive Fred van Beers said: “As the global leader in monopile foundation manufacturing and long-term partner of Dillinger, we can leverage this partnership to support our business as well as the green transformation.
“This agreement is key to decarbonising materials such as steel.
“With this addendum and the MoU between Sif Decom and Dillinger, the partners support development of lower-emission steel manufacturing and circularity of materials used in offshore wind foundations.”
Chairman of the Board of Management of Dillinger Stefan Rauber said: “We are very proud of this future-focused collaboration with Sif.
“It shows very clearly how steel offers various solutions for an intact environment.
“Our steel plates from Dillinger, which in future will be produced with reduced CO2 emissions, are the basis for monopiles and wind farms where renewable energies are generated.
“Now that monopiles can themselves be recycled, this is a real win-win situation for everyone: for the two business partners and for nature.”
