Unfortunately making steel makes a LOT of CO2 emissions. It accounts for 7% of global CO2 emissions. You have to get rid of the oxygen from Iron oxide and that uses carbon and also a lot of heat energy to melt the iron oxide.
So the plan is to build an electric arc furnace to deal with recycled steel instead.
(and to import steel from elsewhere)
It would be interesting to invest in developing steel by using hydrogen to remove the oxygen instead of carbon. Hydrogen could be made by green electrolysis of water.
But that's a whole new debate about green steel technology.
