Denmark’s Orsted yesterday (Wednesday) signed a preliminary settlement with German metal plate producer Dillinger which might see the primary wind farm parts made with H2-derived metal manufactured for the Danish firm by 2028.
Whereas not a dedication to offtake any volumes, the memorandum of understanding (MoU) provides the Danish wind developer proper of first refusal on Dillinger’s low-emissions metal made with hydrogen, as soon as its inexperienced metal plant is up and working.
It places Orsted in place to be one of many first to function wind farms constructed with metal derived from H2, though it’s removed from clear whether or not it will be the very first, and even the cleanest.
In actual fact, the “lower-emissions” metal mooted in yesterday’s settlement might be made with some fossil fuels — with the direct-reduced iron (DRI) used for Dillinger’s inexperienced steelmaking (see panel under) made with 50% methane and 50% H2 to start with.
The MoU between the pair envisages Orsted offtaking “decrease emission” metal plates (a processed metal product) made at Dillinger’s Dillingen metal mill in Germany from 2027-2028, which might be used to fabricate monopile foundations for offshore wind generators throughout Orsted’s huge improvement pipeline.
Dillinger is planning a direct-reduced iron plant at Dillingen, in addition to two electrical arc furnaces at its Völklingen metal plant 400km away, with the intention of manufacturing a complete of three.5 million tonnes of “inexperienced metal” in 2027-2028.

Inexperienced metal producers are planning to make use of inexperienced hydrogen to decarbonise their metal mills, which collectively account for 7-8% of all international carbon emissions.
Historically, iron has been extracted from iron-oxide ore by burning carbon-rich coking coal in a blast furnace, the place the fossil gasoline produces high-temperature warmth whereas concurrently eradicating oxygen from the ore by changing it to carbon dioxide.
This extremely polluting technique will be changed with inexperienced hydrogen in a direct-reduced iron (DRI) facility, the place the H2 reacts with the oxygen to supply steam (H2O) somewhat than carbon dioxide.
In actual fact, hydrogen-based DRI is presently the one confirmed pathway of decarbonising metal manufacturing, when paired with an electrical arc furnace powered by renewable power.
Policymakers need producers to get rid of emissions from the sector by utilizing green-hydrogen DRI that’s then was inexperienced metal utilizing renewables-powered electrical arc furnaces, however with inexperienced H2 costing in extra of €5/kg in Europe, it will end in considerably dearer metal that can require offtakers to pay a premium.
Neither firm has but revealed how a lot lower-emissions metal Orsted intends to contract. Nevertheless, the Danish agency says it has positioned a big order for typical metal, which it believes will underpin among the €3.5bn ($3.83bn) funding essential to carry the DRI plant and electrical arc furnaces to fruition.
“Lengthy-term offtake agreements [of conventional steel] like this one are key to decarbonising hard-to-abate supplies comparable to metal as a result of it takes clear demand alerts to drive investments within the applied sciences wanted to decarbonise manufacturing,” stated Virginie Van de Cotte, chief procurement officer at Orsted.
“With this MoU, we’re happy to assist help Dillinger’s improvement of lower-emission metal services in Europe. That is an settlement which may even allow Orsted to additional diversify its provide chain, safe capability, and ship on anticipated future buyer demand.”
In December 2023, Germany’s federal authorities not too long ago granted €2.6bn in decarbonisation subsidies to metal producers within the Saarland area, the place Dillingen and Völklingen are positioned.
Nevertheless, it’s not clear how a lot of the funding, which is now pending approval from the EU, could be allotted to the 2 vegetation, nor whether or not it will be adequate for Dillinger’s dad or mum firm Stahl-Holding-Saar to sanction a last funding choice (FID).
Course of emissions
The low carbon metal produced at Dillingen would cut back the “course of emissions” from producing the monopiles by 55-60% in comparison with typical metal, Orsted stated.
Metal manufacturing can strategy zero emissions, if inexperienced hydrogen is utilized in DRI manufacturing and if the steel-making course of is powered by renewable power.
Nevertheless, the metal at Dilligen’s mill could be made with DRI produced from a mix of each inexperienced hydrogen and fossil fuel, with solely 50% H2 used at first.
The German firm is concentrating on an 80% hydrogen to twenty% methane ratio by 2030, though this may depend upon the “market availability” of inexperienced hydrogen, a spokesperson for Dillinger informed Hydrogen Perception at present.
“Pure fuel might be used within the DRI plant as a bridge till adequate hydrogen is accessible,” he stated, noting that the plant will solely use H2 made with renewables.
Orsted identified that the corporate struck the take care of Dillinger on the again of the EU’s recently-passed Internet Zero Trade Act, which forces host governments to think about non-price standards when auctioning renewable power contracts.
“Thus, the settlement with Dillinger not solely helps speed up the decarbonisation of the metal trade; it additionally gives Orsted with the optionality to ship on anticipated decarbonisation standards in coming auctions once they materialise,” the corporate stated in a press launch.
Nevertheless, though Orsted is definitely an early mover on utilizing H2-derived metal in its wind farms, it will not be the primary to place them into operation.
Final 12 months Swedish power agency Vattenfall, which is an investor in Sweden-based Hybrit inexperienced metal programme, which makes 100% inexperienced hydrogen-based DRI, introduced that it might begin shopping for volumes of near-zero emissions metal (made utilizing Hybrit DRI) from Hybrit co-investor and metal producer SSAB as early as 2024.
Vattenfall has not specified precisely how it will use the inexperienced metal, ought to the deal come to fruition, saying solely that it may very well be used throughout quite a lot of functions, together with energy strains, hydroelectric dams, grid stations, anchoring for onshore wind energy or components of foundations for offshore wind.
In any other case, hydrogen-based inexperienced metal has to this point not performed a lot of an element in provide chain decarbonisation for wind builders, even though metal makes up 80-90% of a wind turbine’s materials mass and 50% of its complete lifecycle emissions.
Siemens Gamesa is creating a “GreenerTower” for set up on the 1GW Thor offshore wind farm in Denmark, for which it has a take care of Germany’s Salzgitter to acquire low-emission metal plates.
Nevertheless, the settlement doesn’t envisage a provide from Salzgitter’s inexperienced hydrogen-based metal programme, as a substitute utilizing supplies produced utilizing scrap steel and renewable energy.
Danish turbine producer Vestas, together with Orsted, final 12 months agreed to acquire low-carbon metal towers and blades made out of recycled supplies, whereas Vestas has individually dedicated to purchase low-emissions metal from steelmaker ArcelorMittal, made with scrap steel smelted in an electrical arc furnace.
Nordex, in the meantime, has pledged to make all of the blades on its wind generators recyclable, whereas a number of different OEMs have made solely obscure commitments, or none in any respect.
Spain’s Iberdrola has dedicated to make use of 10% of “close to zero” metal throughout all its operations (which incorporates wind developments), 50% low emissions metal by 2030 and 100% low emissions metal by 2050 — a pledge made as a part of the SteelZero programme, of which Orsted, Vattenfall and Siemens Gamesa are additionally signatories.
Hydrogen Perception contacted Orsted for remark however the firm had not responded on the time of publication.
