BENTELER and thyssenkrupp Hohenlimburg agree on supply of CO2-reduced slabs

  • BENTELER and thyssenkrupp Hohenlimburg sign a memorandum of understanding on the supply of CO2-reduced slabs from the BENTELER electric steel mill in Lingen.
  • The use of CO2-reduced slabs from BENTELER complements and supports thyssenkrupp Hohenlimburg's decarbonization strategy.

BENTELER Steel/Tube and thyssenkrupp Hohenlimburg have made a joint commitment to sustainability and climate protection. The companies have signed a memorandum of understanding for the supply of CO2-reduced semi-finished steel slabs from the BENTELER electric steel mill in Lingen to thyssenkrupp Hohenlimburg. The agreement provides for a continuous increase in volume of the material produced with green electricity until 2027.

"Through our sustainable commitment, we are striving to reconcile climate protection and economic efficiency better. At the same time, we are supporting our customers in achieving their own climate targets," says Ralph Mathis, Chief Sales Officer (CSO) at BENTELER Steel/Tube, about the path the two companies are taking.

"We are pleased to have BENTELER as a partner who fully supports our decarbonization strategy by supplying CO2-reduced slabs," says Jens Schöllnershans, Head of Procurement & Supply Management at thyssenkrupp Hohenlimburg. Dr. Henner Diederichs, Head of Sales, adds: "Another milestone on the way to green steel – for our customers and climate protection."

Approval of investment for the conversion of furnace 3 in the precision strip mill – important step toward decarbonizing our production

Decarbonization is currently on everyone's lips. Reducing CO2 emissions and thus becoming carbon-neutral is the goal of all energy-intensive industries, and thyssenkrupp Hohenlimburg is no exception. Numerous projects have been worked through to find approaches to reducing CO2 emissions at the site. The conversion of furnace 3 is a promising one. We would like to give you the chance to take a closer look at the project. First of all, thyssenkrupp AG has supported our project, given the go-ahead, and released the necessary funds for the investment.

With this investment, we are not only bringing the safety technology of the furnace up to date, but also making the furnace itself fit for the future. Stricter emissions regulations will be complied with, while nitrogen oxide emissions and energy requirements in particular will be significantly reduced.

The conversion will be carried out in several stages during our scheduled summer and winter shutdowns. In the individual construction phases, the burner tunnel will be removed and replaced by state-of-the-art side burners. The charging area is being extended and additionally provided with a tightly closing door like furnace 4. The lower furnace chamber is better sealed via new tight shoes and water seals. By taking these measures, we are significantly reducing energy consumption . Currently, we are using pure natural gas as an energy carrier. Once the furnace has been converted, we will have everything in place for using mixed gases, i.e. natural gas enriched with hydrogen. The lower gas consumption will reduce CO2 emissions accordingly. By adding hydrogen at a rate of 60%, our CO2 emissions are reduced from around 90 kg to around 50 kg per metric ton of steel heated. Due to the enlarged charging area, the existing furnace pulpit is being dismantled and rebuilt between the furnaces.
