It is pretty fascinating to see CO2 Emissions from Bremen, seeing that our steel production is about 58% of total of our city.

That means, no, there is no way around it than to improve there.

Going all Hydrogen would require ca 1.5GW of Electrolysis capacity, best case only 800 MW.

Europe has about 230 MW as I learned Tuesday.

Furnaces need to be renewed every so many decades. We have the window NOW. Arcelor Mittal operates two Blast Furnaces here.

@mwfc At least there's no shortage of interconnection.

The biggest project under construction is Boden, I believe.

@nemobis

I think the Bremen one is bigger.

Arcelor Mittal is just not giving the final go yet. For various reasons.

@nemobis

The academic project (bigger scope) for it is

This alone is about 30 Mio in Funds.

@mwfc Yes, Bremen would be bigger but Boden has actually started construction already. Next big one to start will be in Austria, I believe. At this rate, Bremen will start after Boden is operational...

@nemobis

Nice!

I know we have 10 MW Eletrolyzers now. And it was a "big step"

And there is some debate whether Bremen is worth it, or going CCS.

Afaik the funding from the political side is a go, AMB just needs to decide.

Scaleup to ca 1GW of Electrolyzer capacity will be a challenge.

But there has been a breakthrough in efficiency from an australian company. They plan commercially rollout in 5 MW modular stacks this year, and seem to be on track.

IIRC EU wants 6 GW for bootstrap.

@mwfc It's all a game of chicken. As soon as the new hydrogen plants come online in Europe, pretty much the entire ACM fleet of plants will become worthless.

@nemobis

From a HyBit Researcher we got some insights and stranded assets and CCS was way too often in the comments.

So some think they can weasel themselves out, yet, we talk infrastructure here. Bremen will not be able to scale up fast enough, so blue hydrogen is talked about, grey as well.

And depending on when we start to ramp up, we will hit a wall.

And like with the replacement furnaces there are timewindows.

I was suprised how fast politics got subsidies ready this time.

And all of the sudden it will become a waiting game for suppliers.

Green transition is such a shitshow of stop and run and cursing.
