Green Hydrogen News: 10,000 Tonnes Offtake Deal Powers Salzgitter’s Low-Carbon Steel Transition

Exciting news in the world of green hydrogen! Salzgitter AG and EWE AG have just made a significant move by locking in a binding offtake agreement for around 10,000 tonnes of green hydrogen each year. This isn’t just another announcement; it marks a pivotal moment in the clean hydrogen news landscape and aims to transform the steel industry through Salzgitter’s innovative SALCOS® program. The idea is simple: replace coal and coke with hydrogen in direct-reduction plants, aiming for a staggering 95 percent reduction in CO₂ emissions over the next ten years. Starting in 2030, Salzgitter’s steelworks will tap into hydrogen produced by coastal electrolysis plants in Emden, showcasing the bright future of hydrogen production methods in heavy industry.

Sealing the Deal

This is a bold step for both companies, highlighting the potential behind clean hydrogen offtake agreements. Just this month, they finalized their supply contract in Berlin, covering roughly 10,000 tonnes of green hydrogen annually, with deliveries set to kick off in 2030 and lasting for an initial seven-year term. To put it into perspective, this volume is just a fraction of the total 150,000 tonnes that Salzgitter’s direct-reduction plants could eventually need each year. What’s really cool is that Salzgitter will complement this external supply with its own 100 MW electrolyser right on-site, striking a flexible balance between imported and locally-produced hydrogen. The cherry on top? With this contract in place, both companies have positioned themselves to take some financial risks off the table, making their clean steel ambitions financially viable at a larger scale.

Secret Sauce: Green Hydrogen Production

The backbone of the SALCOS® program is a comprehensive electrolysis network in and around Emden, led by EWE AG as part of its Clean Hydrogen Coastline initiative. Designed with the future in mind, these electrolysers are anticipated to reach up to 400 MW of capacity, leveraging abundant offshore and onshore wind resources to generate electricity that splits water into hydrogen and oxygen. With a projected annual output of roughly 40,000 tonnes across various sub-projects, this setup represents the latest hydrogen production technologies at play. Plus, since it eliminates the need for fossil feedstocks, it tackles CO₂ emissions head-on while providing a scalable framework for green hydrogen production in coastal areas.

Hydrogen Infrastructure Backbone

Supporting the hydrogen flow from Emden to Salzgitter is a robust hydrogen infrastructure network. EWE is revamping existing natural gas pipelines and laying down new dedicated lines to transport H₂ to heavy industry sites further inland. Additionally, underground salt-cavern hydrogen storage facilities close to the coast will buffer large amounts of hydrogen, helping to manage the ups and downs of wind-generated electrolysis. This integrated approach ensures that Salzgitter’s steelworks receives a steady, industrial-grade hydrogen supply, even during periods when renewable energy availability varies. Not to mention, this all contributes to Germany’s ambitious plan for a 1,800-kilometer hydrogen core network, paving the way for a cleaner, greener energy future across the continent.

Built for the Future: SALCOS® Transformation

The SALCOS® initiative (that stands for Salzgitter Low CO₂ Steelmaking) outlines how Salzgitter plans to shift from traditional blast-furnace operations to a more hydrogen-friendly DRI-EAF (Direct Reduction Iron – Electric Arc Furnace) process. In the initial phase, natural gas will be used to convert iron ore into sponge iron, cutting emissions by around 60 percent compared to traditional coal methods. As the proportion of green hydrogen increases, the primary reduction reactions will produce water vapor instead of CO₂, bringing us closer to carbon-neutral steel. Then, electric arc furnaces will melt this sponge iron using renewable energy. By gradually boosting hydrogen input and adding capacity, the SALCOS® framework is set to grow alongside the expanding demand for sustainable materials.

Public Backing Moves the Needle

It’s important to note that this isn’t just a private venture funded entirely by corporate dollars; Germany’s federal and state governments have stepped up to the plate with over €1.3 billion for the first stage of SALCOS®’s expansion—€925 million from the Climate and Transformation Fund and around €397 million from Lower Saxony. Another €267 million is earmarked for EWE’s hydrogen production facilities in Emden. These investments underscore that policymakers are keen to lead the energy transition while protecting critical jobs in the process. This initiative fits neatly into Germany’s National Hydrogen Strategy, which prioritizes green hydrogen for sectors that are tough to decarbonize, like steel and chemicals.

Real-World Impact and Challenges

The partnership between Salzgitter and EWE isn’t just an industry win; it anchors a massive investment wave in low-carbon steel and hydrogen infrastructure throughout northern Germany. This investment safeguards thousands of jobs in industrial sectors while helping Europe maintain its competitive edge in automotive and machinery supply chains. Plus, it delivers valuable insights into running large-scale electrolysers, hydrogen purity controls, DRI-EAF integration, and cavern storage dynamics. This data will sharpen future strategies for hydrogen production and hydrogen storage methods.

For industries like automotive, construction, and engineering, this agreement opens the door to certified green steel that aligns with strict ESG criteria. It’s a tangible solution that shows how smart hydrogen project financing can turn climate goals into reality.

That said, challenges remain. Currently, green hydrogen tends to be pricier than gray hydrogen due to factors like electricity costs and capital intensity. Ongoing issues like high grid fees in Germany make it essential for continued policy backing and an optimized market design. We may even need contracts-for-difference or carbon pricing methods to stabilize the situation. Furthermore, having clear regulatory definitions for renewable hydrogen, streamlined permitting for hydrogen pipelines, and consistent EU rules for cross-border trade will be critical. If not addressed, many ambitious projects might stay stuck in pilot stage instead of scaling to needed industrial levels.

Bottom Line

All in all, projects like this one will shape our journey toward a net-zero future by demonstrating that low-carbon steel can indeed be produced for tomorrow’s world. The Salzgitter and EWE offtake agreement is a shining example of how industry, government, and innovation can come together to champion green hydrogen production and support robust hydrogen infrastructure, helping tackle carbon challenges head-on.
