ArcelorMittal’s Duisburg Steel Exit: Did Germany’s Green-Energy Gamble Kill 550 Jobs—or Is the Viral Story Wrong?
ArcelorMittal plans to stop primary steelmaking in Duisburg in 2027, affecting around 550 jobs. Expensive energy matters—but the plant was not converted into the green-steel furnace described online.
Another major German industrial site is shrinking, and around 550 jobs are in danger. But the viral explanation—Germany forced ArcelorMittal’s Duisburg mill to become ‘green steel,’ electricity exploded in price and the converted factory immediately failed—combines real industrial pain with an inaccurate timeline.
ArcelorMittal says it plans to stop primary steelmaking at Duisburg-Ruhrort in October 2027. The steelworks, continuous-casting operation and billet mill would close, subject to approval by the company’s supervisory board. About 550 of the location’s roughly 800 positions could be affected.
The entire site is not disappearing. Its wire-rod mill is expected to continue, using billets supplied by ArcelorMittal’s Hamburg operation and external producers. ‘Plant closes’ is therefore a powerful headline, but ‘primary production ends while downstream rolling remains’ is more accurate.
The immediate operational problem is an expiring supply agreement. Since 1997, Thyssenkrupp Steel has delivered liquid pig iron to the Duisburg works. That contract ends in September 2027. IG Metall has put recent annual deliveries at roughly 750,000 tonnes. ArcelorMittal concluded that alternative crude-steel production options were not economically sustainable.
Energy costs are part of the crisis. Steel production is energy-intensive, and German industrial electricity remains expensive relative to several international competitors and some neighboring countries. The Iran war has added fresh energy-price pressure to an industry already adjusting to the loss of cheap Russian pipeline gas.
Yet Duisburg was not a completed showcase electric-arc furnace that failed after conversion. The existing route depended on imported pig iron. ArcelorMittal had discussed lower-carbon changes at German sites, but the best-documented decision in 2025 concerned separate hydrogen and direct-reduction projects at Bremen and Eisenhüttenstadt.
The company rejected €1.3 billion in subsidies for those projects, saying Germany lacked competitive, predictable electricity and a sufficiently mature hydrogen market. That retreat is relevant evidence about the green transition’s economics. It should not be transplanted into Duisburg as if the promised equipment had already been built there.
Market weakness matters too. European steel demand has fallen, imports have gained share and producers face competition from countries with cheaper energy, newer plants or state support. ArcelorMittal has argued that decarbonization adds costs before customers are consistently willing—or required—to pay a green premium.
The claim that sanctions destroyed Duisburg because it could no longer export to Russia is less well supported. Sanctions, the Ukraine war and lost Russian energy changed Europe’s industrial environment. But company and union accounts emphasize the pig-iron contract, energy prices, demand and import competition rather than a decisive lost Russian export market.
Critics of German climate policy see a warning: closing domestic capacity can reduce territorial emissions while shifting steel production and carbon abroad. That is carbon leakage, not necessarily global decarbonization. The joke that every closure moves a company closer to net zero contains a serious policy challenge.
Supporters of the transition answer that old, emissions-heavy production cannot remain competitive forever and that Germany needs cheaper clean power, hydrogen infrastructure and border measures—not abandonment of climate goals. France’s nuclear-heavy electricity system has helped ArcelorMittal proceed with an electric furnace at Dunkirk, showing that low-carbon steel is not technically impossible.
For workers, the argument is not theoretical. Management, unions and public authorities must negotiate redeployment, retraining, severance and whether investment can protect more of the site. A 2027 timetable offers more room than an immediate shutdown, but uncertainty itself damages families and local suppliers.
Germany faces a choice larger than one mill: subsidize strategic heavy industry, reform power markets, accept higher-cost green production, protect the market from carbon-intensive imports—or allow more basic manufacturing to migrate. Each option transfers costs to taxpayers, consumers, workers or the climate.
Further analysis
The chronology also changes how responsibility should be assigned. ArcelorMittal itself decided not to renew the pig-iron arrangement partly because of its carbon cost, while management and policymakers failed to create a competitive replacement. This is neither a pure government closure nor a simple market accident.
Imports complicate the climate calculation. If European rules charge domestic producers for carbon while allowing cheaper high-emission steel to enter without equivalent enforcement, mills lose market share without a comparable global emissions reduction. The EU’s carbon-border system is intended to address that gap, but its effectiveness and administrative cost remain contested.
What to watch next
Watch the supervisory-board decision, negotiations with IG Metall, the source and price of future billets, and whether Germany adopts an effective industrial electricity price. Duisburg is genuine evidence of industrial strain, but blaming a conversion that never occurred prevents a serious debate about what actually failed.
