Green Steel Production is Gaining Global Momentum Blast furnaces are responsible for approximately 70% of steel production across the globe, but this production method is also responsible for almost two tons of annual C02 emissions. The steel industry is extremely carbon-intensive, and this is mainly due to the blast furnace process, which involves smelting iron ore with coal-derived coke at high temperatures, releasing CO2 emissions. There is a short-term opportunity to overhaul this industry in favor of greener practices, as about 70% of all steel furnaces worldwide will require relining by 2030. Plants already undergoing maintenance could shift toward a newer model of Direct Reduction of Iron ore systems (DRI) powered by hydrogen, feeding into Electric Arc Furnaces (EAF). If the electricity powering the furnaces is renewably generated, this sector could effectively eliminate all harmful emissions.

I prefer the silver/gray color myself, machining green steel would make funny looking chips 😅!

2moYou make something very complex seem so simple. Couple things to consider: is green steel cheaper than conventional steel for the same quality/grade of material? If not, stop the silliness. Also your dreaming if you think the intermittent renewable electricity is going to power a steel plant (economically). It takes about 1MW to melt 1 ton of scrap steel in a EAF. So 100 Ton ladle needs 100MW. 15 min later the first 100 ton goes to the next station and another 100 ton ladle comes in. 400 tons an hour for one EAF. With solar your stuck with one shift. No second or third shifts. With wind, if it’s not blowing your not producing.
