Due to the use of large amount of coke for iron ore reduction, the conventional blast furnace–BOF route is the steelmaking route with the highest CO2 emissions. That’s why we help our customers to introduce new integrated process solutions that enable to drastically reduce their CO2 footprint, such as direct reduction plants or the enhanced furnace technology EASYMeltTM.
Our metallurgy team in Luxembourg is currently working on a new furnace that achieves a CO2 savings potential of up to 70 percent. The EASyMeltTM is an electrified direct reduction and melting process, using a minor quantity of coke and gases like natural gas, coke oven gas, cracked ammonia and hydrogen. In brownfield, EASYMELTTM is less CAPEX-intensive than any other low-carbon ironmaking technology. Thanks to high flexibility in raw material quality and energy sources, the production cost is low and can be optimized according to market conditions.
Direct reduction Midrex® technology is a well-established alternative when it comes to steelmaking from virgin materials. In terms of decarbonization, the Midrex® plant's carbon footprint is around 60 percent lower compared to conventional technology. In addition, it can be gradually converted to hydrogen supply so that with minor changes to the plant and its operating parameters, it can achieve complete carbon neutrality. As a result of a construction license agreement with Kobe Steel in Japan, SMS group is able to offer Midrex® direct reduction ironmaking plants as part of its portfolio.
