AI Summary

A recent study has found that the use of a nickel oxide catalyst can significantly improve the efficiency of hydrogen-based steelmaking. This improvement is attributed to a doubling of the process's rate of reduction. The development is significant in the context of efforts to reduce greenhouse gas emissions from industrial processes. Hydrogen-based steelmaking is seen as a promising alternative to traditional methods, as it can produce tailored steels and metals without generating CO2 emissions.
