Turns out she didn't actually like doing crafts, just buying/collecting the supplies to do crafts. She gets joy from buying things in preparation for doing things but not from doing things.

Carbon steel is very much needed in a lot of places. It is harder than mild steel and is used in axles, gears, cutting tools etc.
SSAB HYBRIT technology replaces the usage of coal/coke in the iron reduction stage with hydrogen which is nice since it only produces water and not CO2. But I can't find any information regarding the carbon content of the resulting sponge iron. If the carbon content is too low you still need to add elemental carbon in some form.
Found all the answers I was looking for. :)
The resulting sponge iron is 0% carbon meaning you need to add carbon in some form. The broschure mentions the use of either biocarbon or a small amount of natural gas. So no need for coal. Neat. :)
