Posco, BHP team up to advance hydrogen steelmaking
Posco and BHP have partnered to test BHP's iron ore for Posco's HyREX hydrogen-based steelmaking technology, aiming to reduce carbon emissions. The companies will share technical expertise and explore emission reductions. Posco's HyREX process uses hydrogen instead of coal, and the collaboration could expand the use of Australian iron ore in low-carbon steel production.
