Good question, so I googled that. I found a story from 2020 about a company in Sweden that had developed a process for making fossil fuel-free steel. A followup story from 2021 said they had just completed their first batch and that they've found a customer in Volvo.

Here's another article.

It sounds expensive.

US companies won't do it on their own unless someone gives them a reason.
