Bit ironic to say they are decarbonizing the steel industry

Wow, all these amazing discoveries we hear about every day being posted on literally-who websites and reposted by literal karma bots. The future is bright!

Hey, SSAB is at least underway. Not the same method but the results are at least fossil free Steel.

In other European countries they try to use hydrogen to decarbonize steel production. Remains to be seen which solution is more efficient.


MrNokill t1_j65mg03 wrote

Grey hydrogen, so it's gas powered steel production in a way, at least they want to make it electric at the factory and burn the gas on sea for making the hydrogen, so it's not polluting the land area as much.

Good thing regulations aren't upheld or steel production would shut down.

This is the best tl;dr I could make, original reduced by 71%. (I'm a bot)

That’s a first.

No it isn't. Vattenfall did it 2 years ago, too (different process).

And China did not used hydrogen to make noncarbon steel from some time?

"their technology aims to convert this carbon dioxide into carbon monoxide"

Carbon monoxide is deadly to humans. One wonders if they can do this without harm to the workers.

The rest of the sentence which you cut off:

>their technology aims to convert this carbon dioxide into carbon monoxide that can be reused in the iron ore reaction.

Presumably, if they're capturing and reusing a gas, it would need to be contained, and thus isolated from the workers.

Plus, I don't think CO is so deadly that leaks would be immediately dangerous. They could be detected and workers evacuated before any ill effects happen.

CO Leaks are immediately dangerous. 1.3% in an atmosphere is unconsciousness after 2–3 breaths. Death in less than three minutes. Don't ever assume chemicals are safe because they don't sound or feel dangerous. More than 100,000 people in the U.S. visit the emergency department each year due to accidental CO poisoning.
