Iron ore rivals BHP and Rio Tinto are collaborating on the development of an electric smelting furnace in Australia. They contend that the technology could reduce the carbon dioxide pollution intensity of steel-making by 80 per cent compared with standard blast furnaces. Steel is one of the world’s most widely-used construction materials, but current production methods generate massive amounts of greenhouse gases. The International Energy Agency has warned that the steel industry is currently not on track to meet the net-zero emissions target of 2050.

BHP estimated in 2020 that 72 per cent of the world’s steel mills are blast furnaces, which use iron ore and coking coal. However, they also generate carbon dioxide in the steel-making process, even if the plant is powered by renewable energy. Electric arc furnaces are an alternative to traditional blast furnaces, and use either scrap metal or direct reduced iron as feedstock. Rio Tinto is working on a project to make direct reduced iron using ‘green’ hydrogen rather than methane, which is a greenhouse gas. Rio Tinto has cautioned that converting the world’s steel industry to this process would require massive amount of renewable energy.

Rio Tinto has signed a memorandum of understanding with China Baowu Steel Group and Tsinghua University to develop strategies aimed at reducing carbon emissions across the steel industry. Steel-making accounts for the bulk of Rio Tinto’s scope 3 emissions, which totalled 536 million tonnes of carbon dioxide equivalent gases in 2018. In contrast, its scope 1 and 2 emissions totalled 28.6 million tonnes. BHP also recently revealed plans to address its scope 3 emissions.
