The two sides will jointly explore a series of new projects in China and Australia, aimed at helping the steel industry value chain achieve decarbonization. According to the memorandum of cooperation, both parties will research, construct, and demonstrate an experimental scale electric melting furnace at the steel plant of Baowu Group, realizing the direct reduction iron technology for the production of medium and low-grade ores for low-carbon steel production. Simultaneously optimizing the pellet production technology of Australian ore to provide support for its use as a raw material for low-carbon vertical furnace production of direct reduced iron; Expand the development of Baowu Group's hydrogen rich carbon cycle oxygen blast furnace technology, which can significantly reduce the carbon dioxide emissions generated by the blast furnace process. Both sides will also jointly study the production of green and low-carbon ironmaking machines in Western Australia
