thyssenkrupp greenlights building of €2B hydrogen-powered direct discount plant for low-CO2 metal


The Government Board of thyssenkrupp AG has launched the corresponding capital sources for the development of the primary direct discount (DR) plant at its Duisburg web site. The Supervisory Board of thyssenkrupp AG helps this resolution. The foremost challenge stays topic to public funding.

The plant, with a capability of two.5 million metric tons, will keep away from the emission of three.5 million metric tons of CO2. Development will contain funding of greater than €2 billion.


thyssenkrupp will construct a €2B hydrogen-powered direct discount plant at its Duisberg web site. Capability shall be 2.5 million metric tons.

The discharge of this monumental funding comes within the midst of the corporate’s transformation, in what can be for all involved a particularly difficult surroundings. We’re thus underlining our declare to make a big and, above all, speedy contribution to the inexperienced transformation—additionally the place metal is anxious. It is a additional step for our staff at Metal Europe, for our companions and for the Ruhr area. On this area, we’ve all the pieces that’s wanted for a profitable inexperienced transformation. That’s the reason the Ruhr area is taking part in a number one position within the power turnaround. We’re firmly satisfied of this, and that is additionally borne out by this funding, which heralds a brand new period for metal manufacturing within the Ruhr area.

As a part of its tkH2Steel transformation challenge, coal-based blast furnaces shall be changed by hydrogen-powered direct discount crops. In distinction to a traditional blast furnace, DR crops don’t produce scorching metallic, however stable sponge iron (Direct Lowered Iron, DRI). The DRI should then be melted down right into a scorching metal-like product in order that it may be additional processed into high-quality metal.

Along with plant producers, thyssenkrupp Metal is growing a power-operated melting unit, which is mixed with the DR plant. Direct discount crops with melting models—similar to a blast furnace—repeatedly produce a liquid product corresponding to conventionally produced pig iron.


Because of this, the brand new DR and melter crops may be seamlessly built-in into the prevailing metallurgical plant. Present and confirmed processes within the Duisburg-based BOF (primary oxygen furnace) meltshops may be maintained. The liquid product is processed into the confirmed metal grades there. Thus, the Duisburg steelworks is continuous to boil metal as previously—however with hydrogen and inexperienced energy as a substitute of coal. The feasibility, scalability and innovativeness of this idea have been confirmed by scientists from RWTH Aachen College in a examine commissioned by thyssenkrupp Metal firstly of 2021.

The primary direct discount plant with downstream melters will provide our clients with over two million metric tons of low-CO2 premium metal per 12 months within the foreseeable future, considerably greater than beforehand deliberate. We’re thus reaffirming our purpose of taking part in a number one position within the competitors for the inexperienced metal markets of the long run and supporting our clients in reaching their decarbonization targets. As well as, we’re fulfilling our social duty and can already be lowering the CO2 emissions of our manufacturing by slightly below 20 % in step one. That’s already 5 % of the Ruhr area’s greenhouse gasoline emissions. Our tkH2Steel transformation challenge is the important thing to this.

—Bernhard Osburg, Chairman of the Government Board of thyssenkrupp Metal Europe AG

With its capability of two.5 million metric tons of direct lowered iron, the primary plant shall be bigger than initially deliberate. On this means, thyssenkrupp is accelerating the beginning of low-CO2 metal manufacturing. On the identical time, the rising demand for climate-friendly metal is being taken into consideration and the ramp-up of the hydrogen financial system is being accelerated.

Within the new plant idea, the whole premium product portfolio can thus be produced with low CO2 emissions with out compromising on high quality.

With the rise in plant capability, thyssenkrupp Metal has additionally considerably raised its local weather targets.

By as quickly as 2030, we’re planning for round 5 million metric tons of low-CO2 metal, which can ship CO2 financial savings of properly over 30 %. The now imminent building of one of many largest hydrogen-powered direct discount crops deliberate up to now will even generate innovation and employment within the Ruhr area and past. The clever mixture with newly developed melting models can function a mannequin for a lot of different decarbonization initiatives within the metal business worldwide. To be able to proceed our transformation at once, we’re planning to award the contract within the fall and we’re already making applicable preparations.
