What the link is "conveniently forgetting" to mention is that most industrial hydrogen production emits CO₂ (steam reforming: CH₄ + 2H₂O → 2H₂ + CO₂). And there's a good reason for that: electrolysis consumes a lot of electricity. I won't do the maths here but, if the electricity was generated through fossil fuels, I wouldn't be surprised if the process actually increased CO₂ emissions instead of reducing them.

But let's say that the hydrogen is from fossil-free electricity. You could be plugging that fossil-free electricity elsewhere instead. The press and media link does not mention that.

>Hydrogen-reduced carbon-free DRI is highly metallized

That can mean two things:

1. They're able to retrieve more iron from the oxide. Good, but it isn't enough to replace the current processes; at most to add hydrogen as the "chef's kiss" to the iron produced through another method.

2. Less cementite aka iron carbide aka the stuff that actually makes steel "steel" instead of plain iron. That's great or awful depending on application.

>has superior mechanical [...] properties

Again, it depends on application. I expect their iron to be rather soft and malleable, but lacking tensile strength.

>This new knowledge is a direct result of close value chain cooperation, determined innovative thinking and bold efforts in piloting new technology – a recipe to copy for other industrial sectors,”

>Hybrit Development AB has filed patent applications describing the included inventions to the European Patent Office.

"Guys, we made something to copy for other industrial sectors, except that we're smearing patents on it so you can't copy the process~".

There's another detail that the press and media link doesn't mention: hydrogen makes steel brittle.
