Credit: Anamul Rezwan from Pexels. Steel production is the surprising source of 8% of all greenhouse gases today. Most of it comes when converting iron ore into molten iron. Usually, that means with coal. Clean-burning hydrogen fuel, on the other hand, which produces only pure water as its byproduct, represents a far more sustainable ...
