Hydrogen-based steelmaking gets 2x boost from nickel oxide catalyst, study finds (opens in new tab)

Steel and metal production are among the largest contributors to global greenhouse gas emissions, accounting for approximately 10% of global CO2 emissions. At the same time, modern technology relies on tailored steels and metals for applications in fields such as mobility, energy, infrastructure, safety and medicine. Hydrogen-based metal production offers a promising CO2-free alternative and goes even further by integrating reduction, alloying and microstructure design into a single productio...
