Austria installs first hydrogen-powered railway line: a milestone in the transition to zero-emission infrastructure
NoticiasAmbientales.com | 12 September, 2025
The Austrian company **Voestalpine** has achieved a historic breakthrough by producing and installing the first railway track made with hydrogen, without carbon dioxide emissions
This development is part of a pilot project at the Donawitz plant. A mixture of scrap and pure iron reduced through the **HYFOR (Hydrogen-based Fine Ore Reduction)** process was used, which employs renewable hydrogen as a reducing agent.
From research to the track: green steel with railway quality
The rail was melted, rolled, and installed at the Linz central station as part of a strategic expansion.
The reduced iron was melted at the **TechMet** research facility. It was then transformed into a rail at the adjacent rolling mill, maintaining the required hardness and strength standards for railway applications.
The final product was installed at the Linz central station...more

Building a Sustainable Tomorrow: Hydrogen Blast Furnaces in Green Steel Production
How long before some Donald Dump choir boy/girl says "But Hydrogen Steel Explodes" ? Not long, because "A cacophony of idiocy". Most of the US won't ever even hear about this anyway.

(36,580 posts)The Germans shut ammonia plants, where hydrogen was made by steam reforming of dangerous natural gas, because their pal Putin, who was funded by Germany when they phased out nuclear power, cut their natural gas off.
Hydrogen is a fossil fuel driven shell game which is conducted at great cost to humanity.
It's telling that the advertisers who come here to rebrand fossil fuels as hydrogen also attack nuclear energy, since nuclear energy is the only tool there is for phasing out dangerous fossil fuels.
I reported recently on a scientific paper as opposed to a slick ad offering a lie that hydrogen is carbon free, the carbon cost of hydrogen production, a cost which is unacceptable:
A fairly comprehensive review of the carbon cost of hydrogen production by various pathways. While the paper itself referenced in that post requires access - which as a scientist I have - the supplemental information, containing the carbon cost of hydrogen production is open sourced.
Irrespective of all the methods listed, the overwhelming method by which hydrogen on this planet is produced is by the SMR reaction, steam methane reforming. The carbon dioxide was product from this exergy destroying practice is dumped into the planetary atmosphere, where it is causing collapse.
Anyone can read it and clearly understand that anyone stating anything using hydrogen is carbon free is lying.
Have a nice weekend.
