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

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.
WikiSummarizerBot t1_j6hc7w6 wrote
>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).

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.
pumpkin_fire t1_j6hdhhi wrote
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.

Is this actually something feasible or another catastrophe like clean coal?
PaulThePaul t1_j6hwj0v wrote
The problem is meltig steel even if its recycled needs very high temperature. And these temperatures are mostly generated by coal as far as I know.

Oh.. so we invest less than 1/20 of the CEO od Lucid Motors salary? Level of effort is pretty low.
BoyInBath t1_j6i1aj2 wrote
Electric forges are theoretically possible at the size and scale needed, but the energy to use them is not cost effective, sadly.
Hydrogen... Maybe - but like most eco solutions, they're not as energy dense, or as cheap as existing fossil solutions.

This has nothing to do with hydrogen production. It’s an electric furnace for smelting iron in to steel.

From the post I replied to or did you not read that part?
RandoRoc t1_j6iiazr wrote
My understanding is that this has to do with the technique to make steel, so the product at the end is the same, but coal isn’t being used to produce it. The clean coal thing was a bit goofy where they were claiming a different end product (if I’m not mistaken it had to do with sulfur content, which is a cause of acid rain) but yeah, burning the coal itself is still going to produce a lot of greenhouse gases that are responsible for climate change/ global warming.

Yeah, I believe that this is using a new method that was developed in the UK that removes the need for coal coke? Saw it a few weeks back in r/futurology but didnt actually read the paper.
Sebulano t1_j6ipjyl wrote
That covers the electrical bill for producing one serving bowl made out of green steel. This has been tested in Sweden already and we are going absolute suicide by planning to upscale this. One factory making green steel needs its own nuclear power plant of energy to produce without downtime it’s crazy when you think about it as we are doing wind based power now. How many windmills will you need per factory you think?
Ok_Champion6840 OP t1_j6j5wbc wrote
Never heard someone call a GW wind turbine a windmill except for former president the white scrotus. In any case, as with all other arguments around gas heat, gas stoves, etc, we need to leverage economies of scale to produce clean power and distribute it where needed for all kinds of uses. Thankfully it can be transmitted over wires, generated locally, accommodate virtual power plants, will benefit from nuclear fission or fusion (when or if that comes about) or hydro power or geothermal applications.

We don’t need money being invested into these processes yet. The generation of energy is the thing that is stopping further advancement in green technology. Without cheaper ways to generate electricity and distribute it these funds are pandering to the general public.
Ok_Champion6840 OP t1_j6kl2x9 wrote
Progress on renewable energy generation is happening in a dramatic way. It is also important to prove out how existing manufacturing can take advantage of electricity as the power source rather than direct burning of fossil fuels by industry.
lemmeeatyourass t1_j6klofg wrote
It’s not really, the process to create the material is still behind from the actual generation. Solar wind and hydro are making great strides in terms of Watts and consistency. But the end result as in storage is still also behind. We can create ways to make steel factories use green energy to heat the steel but from what I see in the power industry it’s very costly to set it up.

Ok_Champion6840 OP t1_j6knmb5 wrote
It is extremely expensive to redesign an industrial scale process like steel making which consumes acres, possibly hundreds of acres of plant space, has logistics like rail access or shipping, mountains of coal ready to be consumed as fuel or massive pipelines of natural gas.
Gotta start somewhere.

This right here. Worked at one of their Arkansas plants two years ago and generally speaking there are some opinions on "green steel."
Oftentimes the impact of green steels like the newer hydrogen process is higher than using DRI and an EAF. People just don't wanna hear that yet.
