This program examines the opportunity for Australia to realise a new high-value export stream in the form of renewable metal refining, with emphasis on refining of iron ore to produce ‘green steel’. We evaluate the full value chain including refining processes that use hydrogen instead of the predominant metallurgical coal (which Australia also exports in world-leading quantities). The work spans process engineering, physics, techno-economics, macroeconomics, policy and urban planning.
