no, a natural gas pipeline cannot ever carry „green hydrogen“, Norbert, wherever in Russia that’s supposed to come from...
Uh... what? :blink: Do you have a link? I want to know more.

You mean him saying that or why hydrogen doesn’t work in a NG pipeline? :p

1:
2: actually scratch that wiki entry, that doesn’t really help... Basically it’s the physics, as (pure) H2 requires substantially different operational parameters than what is used for CH4. There is a possibility of adding H2 to the CH4, but the limit for that in the (German) grid is 5%.
Still leaves the question of where the H2 is supposed to come from... Russia isn’t really known for their progressive renewables development and grey/blue H2 doesn’t help anyone from a CO2/climate standpoint. To be fair, I don’t have a direct quote from someone I’d consider knowledgeable because that tweet is too insignificant to warrant any such comment.

edit2: there’s some detail about H2 in steel pipes here, but not quite what I’m after https://www.mannesmann-linepipe.com...on_gasfoermigem_Wasserstoff_via_Pipelines.pdf

edit3: this is better and comes with a sufficiently scientific background https://www.materials.fraunhofer.de...ng-von-wasserstoff-fuer-die-energiewende.html
Das Problem dabei ist, dass Wasserstoff die Festigkeit und Zähigkeit von Werkstoffen herabsetzen und zu einem spontanen oder auch zeitlich verzögerten Versagen von Komponenten führen kann. Bei der sogenannten Wasserstoffversprödung dringt atomarer Wasserstoff in das Gefüge von Metallen ein und schwächt die atomaren Bindungen, was zu Rissen und zu Brüchen führen kann.

Okay, that, but let's not be pedantic. :p

I personally believe that an oil pipeline in the same continent from a country that is a well known and extremely trusted ally that already provides most of the oil to the states was not that bad of an idea. Especially since you really no longer can trust countries such as Venezuela, which was the the third biggest exporter of oil to the states just a couple of years ago. This is before noting that other Biden policies are likely to reduce the US ability to generate its own supply.

The one executive order that made me happy is related though, as the Biden administration is rolling back the changes done by the previous one with regards to national monuments and halting the exploitation of land which would no longer be protected by the regulations applying to them. As a place which has diverse and plentiful natural beauty, it is important to preserve it in as much as it can be within reason.


The country does not own the pipeline. It is owned by a company that has something of a history of having problems with spills from pipelines.

Part 2 was a pretty good one, part 1 sounds like something that would've gotten a dozen articles about how that answer meant the end of democracy two months ago.

Hey, it's only the end of democracy if the other guy is saying it.
