Rio Tinto and POSCO, the largest steel producer in South Korea and one of the world’s leading steel producers, have signed a Memorandum of Understanding (MoU) to jointly explore, develop and demonstrate technologies to transition to a low-carbon emission steel value chain.

The partnership will explore a range of technologies for decarbonisation across the entire steel value chain from iron ore mining to steelmaking, including integrating Rio Tinto’s iron ore processing technology and POSCO’s steel-making technology.

The MoU with POSCO underlines Rio Tinto’s commitment to working in partnerships with customers on steel decarbonisation pathways and to invest in technologies that could deliver reductions in steelmaking carbon intensity of at least 30% from 2030 or with potential to deliver carbon-neutral steelmaking pathways by 2050, the company said. Both Rio Tinto and POSCO share the ambition to reach net zero carbon emissions by 2050, it added.

Rio Tinto Chief Commercial Officer, Alf Barrios, said: “This partnership with POSCO, a valued and long-standing customer, demonstrates our combined commitment to working together to identify ways to reduce emissions across the steel-making process. The agreement also complements Rio Tinto‘s partnerships with other customers as the industry focusses on developing technologies that support the transition to a low-carbon economy.”

POSCO’s Head of Steel Business Unit, Hag-Dong Kim, said: “Tackling climate change is a critical item in achieving sustainable development for a better future. On the journey to achieving carbon neutrality with Rio Tinto, we can play an important role of finding a way to build a low-carbon steel industry”
