How do you make cement and steel?
- pfdietz 4y agoIron ore is reduced with hydrogen. Some carbon needs to be added to make steel from direct reduced iron, but that carbon doesn't need to come from fossil fuels. Cement needs heat, but it doesn't need heat from fossil fuels. And cement will need CO2 capture in any case -- even today, half the CO2 emission from cement is the CO2 released by decomposing limestone, not from combustion.
