First hydrogen trains

[izentrop]

On Monday 17 September 2018, two Coradia iLint trains entered commercial service on a line of nearly 100 kilometers. Alstom will supply 14 additional hydrogen trains to the Lower Saxony Local Transport Authority (LNVG) during the 2021 year. http://www.petrole-et-gaz.fr/le-train-a ... axe-12174/

What would be the point of transforming electricity into hydrogen with a yield of 25%, rather than running the train directly on electricity.
Scared of the nuclear but not of a bomb of 12 m of height in full station.
The German Greens have a lot of power

Hello,

What would be the point of transforming electricity into hydrogen with a yield of 25%, rather than running the train directly on electricity.

Ben ... That is to say that all the German lines may not be electrified ...

In any case in France it is so, for example on the Nantes-Bordeaux line, it is always diesels that roll on this line scandalously left in a pitiful state.

On other articles they explain this choice:

This is not to replace the existing electric train but the diesel ones. Why ? Because some lines, as in France, have no power line and create it will cost much too much, not to mention the maintenance. This hydrogen train costs a little more than a fuel oil, but is quickly profitable by its low maintenance cost and has the same autonomy.

But what is the interest of using hydrogen as a substitute for fuel? Hydrogen is made from methane, with a very poor energy efficiency, or electrolysis (and the yield is even worse, especially since in Germany electricity is very carbonaceous); it would be infinitely easier to use methane directly ...

All this strongly smacks of the com 'operation, without tail or head ... Even an economic argument hardly holds up: creating from scratch a "hydrogen" network and logistics is obviously very expensive ...

Pure greenwashing ... unless it'ssolar hydrogen by thermolysis...

What is the most heartbreaking is the journalists who drool over this technology ... and the industrialists who spend millions ...

If they want to clean up the aging diesel fleet, they'd better develop the water injection ... I say that I say nothing ...

ps: the source of the info means everything

But what is the interest of using hydrogen as a substitute for fuel? ..

Currently, much of the 58 million tonnes of hydrogen produced around the world is used to desulphurize fuels. So both directly use hydrogen in fuel cells.

... At least in France that's the case, for example on the Nantes-Bordeaux line, it is always diesels that roll on this line scandalously left in a pitiful state.

I had the opportunity to attend this line and she was downright abandoned. We have better prepare his trip as the sound system does not work and the dirtiness of the windows does not know in which station we arrive!

Heard yesterday while driving [France Info; the reporter asked the question of the origin of hydrogen !!!]:

1) It's Alstom: cocorico !!!!

2) It's a non-electrified line, indeed.

3) Hydrogen comes from the cracking of methane.

So it is a magnificent operation of "greenwashing" with "cocorico" sounding (otherwise, the French media would not even talk about it). And indeed, a gas turbine would have been much simpler! Even a gas engine !!!! But no one would have talked about it!

[40 years ago, a "turbotrain" circulated between Strasbourg and Lyon, running on kerosene / helicopter type turbine. Its characteristic noise was known to those frequenting Strasbourg station! Take out the old issues of "Vie du rail"!]

Let's still applaud the fact that French technology is touting something else than nuclear! Band of ungrateful.

The first TGVs that were running on an experimental basis were also kerosene: they produced quite a lot of exhaust gas, with this sweet and sickening smell ...

[Did67]

Yes, it was precisely the babies of the "turbotrain"
