I never understand this, 95% of H2 is currently made from fossil fuels, so this sounds more like greenwashing than anything else. I read about this the other day where Birmingham university have found away to drop steel making CO2 emissions by 90%

thyssenkrupp is investing almost 2 billion euro in hydrogen based steel production

Nor natural gas, which is the route a lot of the European Steelmakers, Acelor Mittal included, have recently announced. Natural gas DRI is around 0.8 t CO2 per tonne of steel Vs 1.8-2.2t CO2 per tonne of steel for coke.

Nah, EAFs mostly melt scrap steel. Maybe some DRI as well. But are incapable of chemically reducing the iron ore to elemental iron.

Boston Melts claims to have developed a process that allows direct electrolysis of iron ore fines into elemental iron, so that the reduction and the refining to steel all happen in the one vessel. Oftentimes, electrolysis of metals involves a carbon anode that still releases CO2 - this is how almost all aluminium is produced. Crucially, Boston Metals claim to have invented an inert anode that doesn't release any CO2.

Electric arc furnace

>An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking. Arc furnaces used in research laboratories and by dentists may have a capacity of only a few dozen grams. Industrial electric arc furnace temperatures can reach 1,800 °C (3,300 °F), while laboratory units can exceed 3,000 °C (5,400 °F).

The article is pretty vague about the process, but it sounds like something close to existing electric arc furnaces. It's unclear by the way the wording what the difference between EAF and that new tech is.

Green steel is often used to make bombs. Huge order came in right after 9/11 at the steel plant my dad worked at.

I guess we can stop blaming the latest three presidents on losing steel jobs.

Correct. That’s why it’s better to “gift” the stuff before they pass

Steel made without coking coal

put the ore in a box and electrocute it

still, this is a shitty headline

Never heard of this before, what is “green steel”?

In most provinces, countries, states, etc. only those who have signed the contract for the debt, and the "Estate" of someone who has passed away owes back debts. So things that you own are to be sold and liquidated to pay off debts. Once all debts have been paid, only then can things of the estate be given to heirs.

If you owe 80k and have 100k in the bank in cash, you can just pay it off. Then your house or car or belongings, etc. go straight to the heirs.

However if you owe 80k and have only 60k in assets, those things would have to be sold to pay off the estate's dues and there would be no inheritance.

The german isn't correct either.

If it's private, they might have to I think.

97% of steel by product is recycled so it's interesting to see it taken even further

Or children?

Next they will use blue steel.

Now if we can just get Zoolander's Blue Steel, we'll be set.

The written Korean is not even remotely correct to congratulations… I guess they couldn’t even Google translate 🤷‍♂️ smh
