Abstract
The metal industry alone contributes to about 8% of the CO2 emissions globally. For a sustainable and carbon-neutral metal industry, the use of H2 and biocarbon for the substitution of fossil carbon is essential. Swerim has in recent years made great efforts to support the metal industry for a smooth C-neutral transition. This paper will highlight the projects using biocarbon and H2 in different metallurgical processes including the installation of an H2-electrolyser which could be connected to various pilot test facilities in Swerim including an EAF, a DC furnace, and a Universal Converter of 6–10 tons in scale. The Swerim H2-electrolyser has the capacity to produce 100 Nm3 of H2/h. Our unique gas processing equipment for the separation of CO2 and production of H2 in combination with our demo facilities enable us to develop high TRL demonstration of different CCUS opportunities for the steel and metal industry. The use of H2 and biocarbon in metallurgical applications will also be discussed.
