Iron as an inexpensive storage medium for hydrogen

This hydrogen is then fed into a stainless steel reactor filled with natural iron ore at 400 degrees Celsius. There, the hydrogen extracts the oxygen from the iron ore – which in chemical terms is simply iron oxide – resulting in elemental iron and water. "This chemical process is similar to charging a battery.
