This plus the recent new way of making steel that reduces carbon emissions by up to 90% would be two huge steps towards more sustainable (and thus, hopefully, more economical) steel market

In fairness, very few things that make processes “more sustainable” reduce costs. They almost always increase costs.

...if you only measure "cost" in the amount of currency you pay for the product today.

My understanding is that the more eco-friendly electric arc furnaces are primarily for recycling steel, which is desirable in western economies where we have a *very* large steel footprint per-capita, but still leaves virgin steel production to blast furnaces (which are are probably better described as carbon release facilities, with steel as a by-product).

Globally, about 70% of steel used is virgin (according to Google), so these developments could be very significant.

If we could inexpensively adopt Nikola Tesla's dream of manufacturing iron and steel electrolytically, as is done with aluminum, and at room temperature, that would help.

Well of course. Any other measure is purely made up. The cost is the cost, not some arbitrary pie in the sky political assessment that is totally unrelated to “cost” at all. Cost is….cost. Measurable in exact terms. Today.

Not necessarily, I wouldn't say forests, oceans etc don't have value just because they haven't been monetized.

Unless you're actually being honest and calculating an appropriate cost for those things, damaging an ecosystem isn't "free" just because no-one sends you a bill.

I was also thinking that as things are right now, energy is becoming more and more expensive, so using more energy efficient methods might lower actual cost. Not for the early adopters, for sure, but when the technology becomes more mature and cheaper to implement

I had no idea that alligators were that smart. This could revolutionize, not on steel production, but production of other metals and products, as well.
