Ways to Future CO2 Emission Reduction in Steelmaking Primary Operations

Oral Presentation New technologies under research and development with a promise to change the future (H2 based, in-bath technologies etc.)


Mr Ingo Both (Paul Wurth)


Climate change and international agreements are calling for radical CO2 emission reduction. Already now, Europe’s benchmark (of CO2 emitted for the production of one ton of hot rolled product) for the Emission Certificates Trade Scheme is about 20% lower than the average of well performing European integrated plants’ current actual output. Scrap based EAF steel has certainly potential to reduce CO2 emissions, however scrap availability and the need for virgin iron suitable for quality steel products limits its share in overall steel production. Paul Wurth sees realistic opportunities for reaching nearly climate neutral steelmaking within a few decades. The basis would be direct reduction of iron ore products by means of hydrogen produced from steam by a highly efficient solid oxide electrolysis. The electric energy for the electrolytic process and the consecutive EAF steel making will come from non-fossil sources. The paper discusses possibilities of stepwise transforming integrated steel plants into production facilities close to carbon neutrality. It also demonstrates examples of practical ways to reduce CO2 emissions classic ironmaking during the transition period.
