HN discussion> For steel the possibilities are hydrogen or electrolysis, both are being tested by some companies. We already have steel recycling plants today that shift ~100% of emissions to thermal energy source, with a hot enough nuclear reactor (G4 MSR, maybe something in fast spectrum, maybe fusion) you can effectively eliminate the majority of steel emissions globally. > Cement is the biggest "we don't really have any good…

on “Concrete: The material that's 'too vast to imagine'”> CarbonCure, a start-up based in Canada, has developed an add-on machine that injects CO2 at the point of mixing the cement with water and sand to create concrete. This permanently stores the CO2 and makes the concrete stronger. I'm very sceptical of this. If you add CO2 to concrete, the extra strength comes from calcium carbonate, which accelerates concrete aging, and generally reduces its useful life. It's never…
