As a reminder, full lifecycle emissions for wind generation for wind and solar are embodied carbon in the cement and steel, and distribution emissions as they cross oceans and components are trucked to sites. Midrex’ DRI makes lower carbon steel using hydrogen to displace some natural-gas sourced syngas and can become much lower carbon still by using green electricity for process heat, green hydrogen, and biomethane.Ĭomparison of as-published and harmonized life cycle greenhouse gas emission estimates for selected electricity generation technologies, by NRELīut with more and more zero emissions steel building the steel infrastructure and trucks of the future, embodied carbon will plummet as well. End-to-end, the process is zero process emissions, although of course there is still embodied carbon in the vehicles and steel and cement used to manufacture and construct the facilities. The HYBRIT project has already succeeded in making steel from iron ore mined in zero emissions mines using green electricity and green hydrogen. We won’t be repowering blast and open-heart furnaces, as we will be making what new iron we require using direct reduction technologies. First off, all energy required for making steel will become electricity. With demand still increasing, albeit more slowly through 2060, will carbon emissions continue to grow? Millions of Tons of Steel Per Year By Method Through 2100, chart by authorīut it begs the question: what will the carbon curve look like? The massive growth in demand from 1990 to 2020 as China brought 850 million people out of poverty and rural areas into middle-class citizens living in advanced, modern cities came with similar growth in carbon emissions.
