Makes sense, given that steel is an iron/carbon alloy. I guess decarbonization would be making the process more efficient and capturing more of the carbon into the steel?
my understanding is yes that's the general avenue people are researching; there's also the actual energy inputs powering steelmaking that hypothetically can be made greener (currently, it's a process that seems to almost exclusively use fossil fuels because of the very high temperatures needed)
