Yes, there's a lot more to the story. The modern developments in steel production eliminate the blast-furnace-to-basic-oxygen-process entirely, by using the direct reduction method (which has used natural gas as the hydrogen source, but it can also use water-sourced hydrogen). Here's a nice visual (gif) comparison of the direct-reduction -> electric-arc-furnace and blast-furnance -> basic-oxygen-furnace method pipelines. They converge on the same point, the steel refining facility: https://www.steel.org/steel-technology/steel-production/ https://www.steel.org/steel-technology/steel-production/ That shows how the process has traditionally been used, and here's how it's modified to eliminate fossil fuel inputs: https://bellona.org/news/industrial-pollution/2021-05-hydrogen-in-steel-production-what-is-happening-in-europe-part-two https://bellona.org/news/industrial-pollution/2021-05-hydrog...
