Reread my last comment, take the time to understand what I’m saying (emphatically NOT that fossil fuels have a part to play) and then explain to me how wind and solar can take the place of the current fossil fuel used in the furnaces to make steel - not as a fuel, but as an essential part of the process. Hydrogen is pretty much the only answer at this stage. It’s not an either/or, because neither does everything, that’s a ridiculous way to look at it.
