Iron

“So, the iron making process, that's really where the major driver of all the greenhouse gas emissions from the, ah, the steel industry come from, and more than 90% of iron made today is made with a single piece of equipment, which is called the blast furnace.”

“Cobalt cathodes are actually the highest performing. And the reason we're on nickel is because it's meaningfully cheaper. And the reason we're on iron is it's yet cheaper still. But both of those are actually lower performing than the cobalt-based cathodes.”

“This company called Electra out of Boulder, Colorado, is working on a process that it's piloted showing that it can get pretty pure iron, like, 99 point odd percent pure, out of this electrolysis process.”
