About 1.9 gigatons of steel is produced every year, emitting 8% (3.6 gigatons) of global CO2 in the process. More than 50% of the CO2 emissions come from a single step of steel production, known as ironmaking. Hydrogen-based direct reduction (HyDR) of iron o ...

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 ...
