Scientists develop clean and efficient new method for iron and steel production

Steel has underpinned modern life for centuries, but it comes at an expensive cost. The industry is responsible for nearly 7 percent of the world’s total carbon dioxide emissions, driven by blast furnaces fueled by coke, a form of coal, to extract oxygen from iron ore. For decades, most attempts at cleaner steel-making, though, have been dashed on the problem of doing it large-scale. Scientists may now have an answer. Transitioning to Hydrogen P…
