Decarbonization Arcelor Mittal, Sekisui Chemical to Capture, Re-Use Carbon Waste Gases
With an investment of 1.9 million dollars, Arcelor Mittal and Sekisui Chemical have collaborated for a project which will focus on capturing and re-using carbon waste gases from the steelmaking process. Sekisui Chemical’s new technology that converts CO2 to carbon monoxide will also be tested at Arcelor Mittal’s laboratory in Spain.
Luxembourg/Luxembourg – Arcelor Mittal and Sekisui Chemical have recently announced that they are partnering on a project to capture and re-use carbon waste gases from the steelmaking process, which holds the potential to reduce dependence on fossil resources and contribute to the decarbonization of steelmaking.
In the project CO2, which would otherwise have been emitted, will be separated and recovered from carbon-rich waste gas from the steelmaking process. An innovative chemical process, developed by Sekisui Chemical in Japan, then converts the waste CO2 into carbon monoxide rich Synthesis Gas (carbon monoxide and hydrogen). The Synthesis Gas is then returned to the steelmaking process as an alternative reduction agent for iron ore, thereby lowering the volume of fossil resources required in the steelmaking process.
Successfully decarbonizing steelmaking will involve multiple technologies and we expect CCUS technologies to have an important role to play.
Key to this work is Sekisui Chemical’s innovative technology that converts CO2 to carbon monoxide at high yield. To date, producing carbon monoxide in large volumes from CO2 has been very challenging. Sekisui Chemical aims to demonstrate the ability to scale up its new technology through this partnership with Arcelor Mittal.
The technology will initially be trialed over a three-year period at one of Arcelor Mittal’s research and development laboratories located in Asturias, Spain, commencing in the third quarter of 2021. The investment cost of the project is 1.9 million dollars.
Pinakin Chaubal, Chief Technology Officer at Arcelor Mittal, said: “This is an exciting albeit early-stage technology which complements our existing carbon capture and re-use or storage technology (CCUS) initiatives. Successfully decarbonizing steelmaking will involve multiple technologies and we expect CCUS technologies to have an important role to play. This view is shared by the International Energy Agency which said in its recent ‘Net Zero by 2050’ report that CCUS technologies will be attached to over 50 % of steel production by 2050.”
