Steel production alone accounts for about 7% of global emissions because of its energy intensiveness. Decarbonisation seems to be an especially hard in this sector, but technologies to do so, do exist. This article clearly outlines ways forward for the steel sector. One of which is an engenious solution using hydrogen energy. It would however an additional 180 GW(!!) of renewables to be able to decarbonize the EU steel sector.

To run in a high renewables energy system, we will have to overbuild our peak power demand by 2 or 3 times. Those times when we aren’t charging up the storage are going to leave us with an awful lot of power to use to create hydrogen.
My point is that probably most of those extra 180 GW are going to be built anyway. And it will be bloody cheap to do it.
Only 180GW? Or is this 180 GW permanent power?
Otherwise, easy.
So fucking do it.
…and require that all new steel must be created with renewables.
Our children are more important than our wallets.
