1 EU Industry Day 22 nd February 2018, Brussel Smart Carbon Usage, Process Integration and Carbon Capture and Usage Michael Hensmann, VDEh-Betriebsforschungsinstitut GmbH (BFI) Dr. Koen Meijer, Tata Steel (TATA) Dr. Markus Oles, thyssenkrupp AG (tk)

2 Technological pathways to reduce CO 2 emissions in the EU 28 steel sector 2

3 Smart Carbon Usage Intelligent use of steelmaking routes with fossile fuels (coal, natural gas, etc.) while at the same time cutting the CO 2 quantities they produce Process Integration Reduced use of carbon and equivalent CO 2 emissions by modifications of existing and alternative ironmaking/steelmaking processes with or without CCS Carbon Capture and Usage Usage of CO, CO 2 with or without Hydrogen as feedstock for valuable products like fuels or basic chemicals 3

4 Process Integration IGAR (Injection de Gaz Réformé) PEM (Primary Energy Melter) Source: ArcelorMittal Source: SMS-Group Reforming of steel plant gases and injection in Blast Furnace to reduce coal/coke consumption New metallurgical process based on low quality scrap melting with metallurgical/natural gas Technology: Plasma torch and reactor to heat and reform gases Potential CO 2 savings: 0,1-0,3 tonne CO 2 per tonne of crude steel For one typical plant 500 ktco 2 eq/a Total EU scope estimated is 10 MtCO 2 eq/a Timeline: Validation in 2020 Technology: Pre-melting of scrap in shaft vessel with gas burners and subsequent superheating process Potential CO 2 savings: 1 ton CO 2 per tonne melted scrap For one typical plant 200 ktco 2 eq/a Total EU scope estimated is 2500 ktco 2 eq/a Timeline: Go to live PEM installation 2019; Integration in

5 Carbon Capture and Usage Steelanol Source: ArcelorMittal Construction of commercial scale facility to create bio-ethanol from steel waste gases Technology: Production of bio-ethanol via gas-fermentation Potential CO 2 savings: If all steel mill gasses of EU 28 conventional steel plants (BF-BOF route) are converted into ethanol the yearly production potential of app. 14,5 million t/y of EtOH will reduce CO 2 emissions by 33,3 million t/y. Timeline: Go to live

6 LowCarbonFuture Exploitation of projects for low carbon future steel industry RFCS accompanying measure project Start of the project: Duration of project: 24 months 6

7 Main Objectives: Evaluation and promotion of projects and dissemination of knowledge dealing with CO 2 mitigation in iron and steelmaking Finding solutions for future collaboration and enabling technology transfer between all actors like steel producers, plant manufacturers, associated industrial sectors (energy, hydrogen, chemistry ), institutes for applied research and universities Generation of a roadmap stating research needs for breakthrough technologies to guide EU steel industry towards the EU climate goals Implementing key findings in the strategic research agenda of the European Steel Technology Platform (ESTEP) Support the update of the Steel Roadmap, EU Masterplan and EUROFER s BIG-Scale initiative 7
