sounds like more than just a little bias from that guy, hydrogen for drivers is very stupid if someone wanted to find a mid ground hybrids are far more effective use of resources than trying to shoe-horn it into ground transportation. For rockets and airplanes i can see a use case, but not for most other transportation.

More importantly why not just use LNG instead of steam forming it to produce the hydrogen, because surely this guy understands that 95% of industrial hydrogen is cracking hydrocarbons and not electrolysis. The article states nothing about hydrogen generation, they all just assume the public will think electrolysis when its far and away the real cost of producing hydrogen at a large industrial scale needed.

Looks like you know something the German government doesn’t know if your only use case is rockets and aeroplanes when they have a fleet of trains already using hydrogen

The German government has a terrible track record on energy sources.

trains work as the infrastructure to charge their cells is more localized.

I don't care about how the German gov't thinks they are smarter, Its pretty obvious they were short sighted in energy generation by going with Russian LNG pipelines and not expecting them to fuck that up. So if that is your standard of smart hydrogen use cases I doubt I will be able to convince you and will just stop trying.

Rockets and Airplanes are the strongest argument for hydrogen due to high impulse energy needed and the fact of losing its weight as it burns the liquid. And to be frank even rockets have higher impulse energy fuels per weight than hydrogen (RP-1 is just nasty stuff to handle), hydrogen is just cleaner to burn.
