Iron- and steelmaking cause ∼7% of the global CO 2 emissions, due to the use of carbon for the reduction of iron ores. Replacing carbon by hydrogen as the reductant offers a pathway to massively reduce these emissions. However, the production of hydrogen ...
Fossil-free ironmaking is indispensable for reducing massive anthropogenic CO 2 emissions in the steel industry. Hydrogen-based direct reduction (HyDR) is among the most attractive solutions for green ironmaking, with high technology readiness. The underl ...

Hydrogen-based direct reduction of iron oxide at 700°C

Heterogeneity at pellet and microstructure scales

Steel production causes a third of all industrial CO 2 emissions due to the use of carbon-based substances as reductants for iron ores, making it a key driver of global warming. Therefore, research efforts aim to replace these reductants with sustainably ...
Iron- and steelmaking is the largest single industrial CO 2 emitter, accounting for 6.5% of all CO 2 emissions on the planet. This fact challenges the current technologies to achieve carbon-lean steel production and to align with ...
Steel is the most important material class in terms of volume and environmental impact. While it is a sustainability enabler, for instance through lightweight design, magnetic devices, and efficient turbines, its primary production is not. Iron is reduced from ores by carbon, cau ...
This is a viewpoint paper on recent progress in the understanding of the microstructure–property relations of advanced high-strength steels (AHSS). These alloys constitute a class of high-strength, formable steels that are designed mainly as sheet products for the transportation ...
