Germany is the largest steel producer in the EU. Around a third of the carbon dioxide emitted by the entire industry in Germany is produced in blast furnaces. An alternative process route of hydrogen based is in sight that will produce almost no CO2, however it will only be fully established in many years. For the transition, German engineers are developing a concept under the coordination of the UDE to recycle the CO2 that is produced. German steel maker Thyssenkrupp is collaborating with Universität Duisburg-Essen and Clausthal University of Technology to develop recycling of CO2 directly in a NuCOWin process, intended as a transitory concept until the industry takes its big step with the transition to hydrogen-based DRI production.Engineers from the UDE are therefore developing a concept together with thyssenkrupp Steel Europe AG and the TU Clausthal as to how CO2 can be recycled directly in the process in the short term. The aim of the NuCOWin project is to answer the fundamental questions of process and plant technology for implementation on an industrial scale.UDE Institute for Metal Technologies Professor & Project Manager Dr Rüdiger Deike said “One should understand: Due to their high energy density, carbon compounds will continue to be indispensable, but the CO2 remains in the cycle. The big challenge is to develop economic processes within the transformation in the steel industry, but also in other industrial sectors, that no longer release CO2 into the atmosphere. To do this, one should understand: due to their high energy density, carbon compounds will continue to be indispensable, but the CO2 will remain in the cycle.”Within the funding program "KlimPro: Avoidance of climate-relevant process emissions in industry", the Federal Ministry of Research is funding the project that has just started for three years with a total of EUR 1.2 million.
