Iron is one of the most common metals in the world. However, it does require a lot of energy to make it, Deen says. While the goal is to use energy sources more efficiently and to produce in a circular way. If perfecting the process succeeds, it solves a huge problem. "Iron powder can then become the energy carrier in coalfired power stations.
