A steel company, mining company and electricity producer partnership have succeeded in producing a form of iron using a nearly emissions-free process. The joint venture’s goal is employing renewable energy to produce hydrogen, and then using the hydrogen, along with iron ore pellets, to make “sponge iron,” which can be used to make steel. These companies are the first to have used this process to produce sponge iron on a pilot scale, a step up from laboratory scale and a sign of progress toward being able to do it on a commercial scale.
