Background

The ThyssenKrupp Steel Duisburg steel plant consists of two plants operating as one location in Duisburg.[1]

In 2020, Thyssenkrupp announced plans to build a direct reduced iron plant with an integrated melting unit run on hydrogen and green power at its Duisburg works to produce green steel.[2] The plant was expected to be completed by 2025 and have a capacity of 1.2 million mt a year. If hydrogen is not available in sufficient quantities by then, the plant will be operated using natural gas.[2] The solid material produced in the direct reduction plant will be liquefied in an integrated melting unit, and the "blast furnace 2.0" will produce "electrical hot metal," processed in the existing metallurgical plant.[2]

Thyssenkrupp set itself the target to reduce its CO2 emissions by 30% by 2030 and plans to complete the main part of the plant by 2025 and produce 400,000 mt of green steel. For 2030, the company's target was 3 million mt of green steel.[2] Thyssenkrupp is Germany's largest steelmaker, and the company's Duisburg steel production site alone accounts currently for 2% of Germany's CO2 emissions.[2]

"The potential for reducing CO2 is also of this magnitude if these emissions can be reduced to zero in the long term," said Thyssenkrupp in a press note.[2]

In the short term, tests are being run using hydrogen in conventional blast furnace operations before the DRI plant is finished.[2]

As of November, 2025, no concrete updates have been made regarding the construction of the DRI plant, however the company confirmed its commitment to the Duisburg transition in June, 2025.[3] In March, 2025, the company stated that they were unsure of the economic viability of the project due to the lack of affordable green hydrogen.[4] Additionally, The company temprarily shut down blast furnace no. 9 at the Duisburg plant in October, 2025 due to weak demand for steel, and in the same month a fire broke out at the recently launched rolling mill due to an explosion in the furnace, causing further downtime. [5]

Thyssenkrupp has been in the process of divesting from their steel holdings due to lack of steel demand and high operating costs, putting all modernization plans in doubt. In September, 2025, Thyssenkrupp recieved a takeover bid from Jindal Steel Company for their steel division, Thyssenkrupp Steel Europe (TKSE).[6]
