The Chemistry Trick Poised to Slash Steel’s Carbon Footprint

Chemists are pioneering a clean, electrochemical method to make iron, a key step in decarbonizing the steel industry. Their process, which uses saltwater and iron oxide instead of carbon-heavy blast furnaces, has been optimized to work with naturally sourced materials. By identifying low-cost, porous iron oxides that dramatically boost efficiency, the team is laying the [...]
