The hydrogen, freed from water, reacts with the oxygen in ore in a machine called a shaft furnace, heated to 1,500*F with fossil-free wind energy and hydropower. ![]() To reduce the footprint, a Swedish industrial consortium developed Hybrit, a steel whose production taps hydrogen, rather than carbon, to transform iron ore. Steelmaking yields between seven and nine percent of the world’s carbon emissions, mostly due to a specially processed type of coal called “coke.” At temperatures as high as 3,000☏, coke reacts with oxygen in iron ore, purifying the metal into a form needed to make steel-but belching carbon dioxide in the process.
