The article doesn't mention it: there is actually a research project in France doing iron oxide electrolysis, but in a different way than what Boston Metal does. It's called Siderwin and steel company ArcelorMittal is involved: https://www.siderwin-spire.eu/ https://www.siderwin-spire.eu/ I recently covered this in an article (though German, in case you understand that: https://www.golem.de/news/eisenoxid-elektrolyse-stahlherstellung-mit-strom-statt-kohle-2112-161461.html https://www.golem.de/news/eisenoxid-elektrolyse-stahlherstel... ). Main difference between this and Boston Metal: They use a relatively cold process (~100°C) while Boston Metal uses a hot process. I guess it's good to try to make this work in different ways.
