Making carbon-free steel with clean electricity
www.volts.wtf
Steel production generates almost 10% of global carbon emissions and has long been considered “hard to abate.” Enter Boston Metal, a startup that aims to make carbon-free steel using only (sing it with me!) clean electricity. CEO Tadeu Carneiro explains “molten oxide electrolysis” and its potential to transform the industry.

This boston company has developed a new process to manufacture steel using zero carbon dioxide and a whole lot of electricity

    Carbon-free steel is just iron

    [Edit] nevermind I forgot that that I don’t know metallurgy lol

      Carbon is just the traditional way of removing oxygen from the iron oxide. There are other ways of purifying the iron. And this method cuts away a lot of steps involving multiple processes and a lot of coal. Give the article a read or listen for more info, it’s really interesting
