Running a capital intensive steel making plant intermittently at 10 or 20% capacity factor is not a break through. It’s economic nonsense. No sane investor would get behind this, when he or she could invest in the same plant running on 24/7 reliable baseload power and make 3X or 5x the revenues. Low temperature is definitely the way to go, though, whenever feasible. People have been trying for over a century and failed. Don’t hold your breath.

Australia’s main iron ore export may not work with green steel making, say researchers. Tessa Leach & Tyra Horngren 2023 Apr 04 Phys.org techxplore.com/news/2023-04-australia-main-iron-ore-exports.htmlHematite reduction traditionally requires Bessemer blast furnaces, far from so-called green steel making. However, new low-temperature methods as reported a bit earlier in this thread might work.

Making Cement From Electricity Slashes Carbon Emissions Steve Hanley 2023 Jun 25 CleanTechnica cleantechnica.com/2023/06/25/making-cement-from-electricity-slashes-carbon-emissions/Terrible title: cement is made from limestone. What has been done is to use electricity, instead of just heat, to make the cement. Further, the traditional process emits carbon dioxide, not just harmless carbon. Finally, the article says nothing about how this has been accomplished @ MIT.
