This actually is a Big Thing. Steel, produced without coal. You might not know this about me, but I actually sold steel as my first job and learned a lot about steel production at Mannesmann a long time ago.

@jwildeboer I like this a lot, however I always thought that steel is iron with a few percent of carbon. So do they mean they just use coal-free ovens, or do they actually also get the carbon inside the steel from something else now?


@Sibbo The hybrit process is coal-free. And yes, the sponge iron it produces is very low carbon, so it must be added back. See for more details.

@jwildeboer Interesting thanks. So majority of coal is saved in the reduction of iron. Thanks for the link, it is a really nice paper!
