    Steel production emits something like 1.4 tons of CO2 per 1 ton of steel made. The steel industry is responsible for about 8% of global carbon emissions. Not only for the high temperatures required but because carbon is used to reduce iron ore to pure iron, and because carbon is a component of steel alloy. Liquid natural gas is used as well, and there’s a “green” version of steel production that uses hydrogen instead of carbon to reduce the iron ore. But today almost all hydrogen is produced from natural gas.

      I was just saying that there might have been a better way to do it but since Porky doesn’t care about “better” it’s never been done, yk?

        I’ve definitely seen big electric arc furnaces in places like China and Korea, although i don’t know if that’s only for steel recycling. Hopefully with how many fucktillion watts of power China is producing now, they can figure out an all-electric method of steel production.
