Deep in Sweden’s icy north sits a small manufacturing facility the place the rustic’s biggest commercial avid gamers had been ceaselessly validating a brand new generation that might blank up probably the most dirtiest industries on Earth.
Power massive Vattenfall, steel-maker SSAB, and mining company LKAB constructed the power — situated within the small the city of Luleå — in 2020, as a part of the HYBRIT undertaking. The initiative targets to turn out that metal will also be made on an commercial scale the use of hydrogen and blank electrical energy.
“The use of hydrogen to provide metal remains to be in its very early levels,” an SSAB consultant advised TNW. “It represents just a tiny fraction of these days’s metal manufacturing.” However that could be about to switch.
How do you are making metal the use of hydrogen?
Metal is among the international’s maximum used fabrics. And its manufacturing is liable for 11% of worldwide CO2 emissions. These kind of emissions are produced when heating and decreasing iron — the core element of metal — in a blast furnace the use of coal and coke (a sophisticated form of coal, now not the comfortable drink).

The HYBRIT generation, on the other hand, doesn’t use a blast furnace in any respect. It makes use of hydrogen as an alternative of coke in a procedure known as direct relief. This reduces iron oxides to steel iron with out melting it. The hydrogen reacts with the oxygen in iron ore, generating so-called “sponge iron.” The one byproduct is water vapour.
On the plant in Luleå, SSAB takes this sponge iron after which melts it into metal in an electrical arc furnace powered via Vattenfall’s wind farms. The result’s just right ol’ shaped metal — however with out the emissions.
Going mainstream
This week, Vattenfall, SSAB, and LKAB offered the result of their six-year trial to the Swedish Power Company. The document displays that the iron produced the use of hydrogen isn’t simply carbon impartial, however could also be more potent and tougher than iron produced with fossil fuels. The companions have implemented for and won a number of patents in response to the effects.
HYBRIT’s pilot plant is the arena’s first to turn out the “fossil-free price chain” for metal on a semi-industrial scale. The manufacturing facility has already produced 5,000 tonnes of hydrogen-reduced iron. And corporations like Volvo, Epiroc, and Peab have already put the golf green metal of their automobiles, equipment, and structures.
The commercial giants will now get started construction a bigger manufacturing facility in Gällivare, 3 hours North of Luleå, within the center of Swedish Lapland. The long-term plan is to construct extra hydrogen iron factories and fully decarbonise metal manufacturing in Sweden — slashing 10% of the international locations emissions.
On the other hand, important hurdles lie forward. Producing enough amounts of inexperienced hydrogen would require consistent provides of fresh power. Additionally, hydrogen is these days a lot more dear than fossil fuels, and the worth isn’t falling as rapid as expected.
Can Europe cling directly to its inexperienced metal tech?
Mining massive Archelor Mittal stated in February that it can not perform its Ecu crops the use of inexperienced hydrogen for the reason that ensuing inexperienced metal would now not compete on world markets. It’s just too dear.
“Growing any totally new generation is pricey,” an LKAB spokesperson advised TNW. “With improve, it is going sooner, however we’re competing with projects that obtain state backing at considerably upper ranges.”
LKAB is for sure relating to the truth that, oftentimes, local weather tech investment flows extra freely outdoor Europe, fuelled via huge public spending like Biden’s $1 trillion Inflation Aid Act.
In March, the USA pledged as much as $1bn for 2 inexperienced metal projects. US steelmaker Cleveland-Cliffs will construct probably the most crops. The opposite might be built via none as opposed to SSAB, the use of the hydrogen relief generation evolved beneath HYBRIT.
Ecu policymakers would do smartly to learn the writing at the wall and spice up investment for local weather tech — or possibility proceeding the pattern of forcing homegrown generation to mature on overseas shores.
It’s now not all unhealthy information, on the other hand.
H2 Inexperienced Metal, one in every of Europe’s easiest funded startups, has selected a website in Boden, Sweden, for its first commercial plant. The startup expects to roll out the primary business batches of its metal via 2025 and targets to provide 5 million tonnes of inexperienced metal a 12 months via 2030.
H2 Inexperienced Metal has additionally signed an settlement with Iberdrola to construct a plant powered via solar energy in Spain, whilst GravitHy plans to open a hydrogen-based metal plant in France in 2027.
