In this section you can read news on Direct Reduced Iron, DRI. DRI is a steel production process to produce steel using (green) hydrogen to reduce the iron instead of carbon intensive coking coal. Hydrogen is used as main reduction agent in the process of making sponge iron through the direct reduction of iron or in the furnace. The resulting sponge iron is used in the further production of steel.
As part of POSCO’s strategy to achieve carbon neutrality by 2050, the company is actively engaged in activities to secure low-carbon steel raw materials in Australia.
One of the world’s largest industrial decarbonization projects gets underway with an order volume for SMS alone of over 1.8 billion euros.
The ArcelorMittal Dofasco plant will transition away from the basic oxygen furnace steelmaking production route to the DRI – Electric Arc Furnace (EAF) production route.
Midrex’s owner, Kobe Steel is further solidifying the partnership by investing in H2 Green Steel as part of its Series B financing round.
Mubea aims to be climate neutral as early as 2035 and to reduce the total CO2 emissions of its business activities by at least 25 percent as early as 2025.
thyssenkrupp is accelerating the start of low-CO2 steel production and making an important contribution to achieving national and European climate targets.
Find here some commonly asked questions about Direct Reduced Iron (DRI) and their answers
The industrial production of iron starts with iron ore, a naturally occurring mineral. Chemically, iron ore consists of iron and oxygen, mostly in the form of magnetite (Fe3O4) or hematite (Fe2O3). That oxygen is traditionally removed in a blast furnace by combining it with carbon. Alternatively, the oxygen can be combined with hydrogen or carbon via a process known as direction reduction of iron, or DRI for short. Both routes produce impure forms of iron which requires further processing to yield usable iron and steel products.
The direct reduction of iron (DRI) is a more energy efficient route to produce iron from iron ore than the traditional blast furnace. Moreover, if hydrogen is used as the reductant instead of carbon, then DRI can eliminate the formation of carbon dioxide, seen as a major contributor to global warming.
After production, direct reduced iron (DRI) will immediately start to re-oxidise. This process emits energy in the form of heat, creating a risk of self-combustion. Hence when shipped, DRI is often kept under nitrogen, which is an inert gas. Re-oxidation can be slowed by processing DRI into larger forms, such as briquettes. In many cases, the DRI unit is part of an integrated facility, whereby all DRI is quickly processed further into more stable forms of iron and steel.
