Hydrogen Hype is Dying, And That's a Good Thing

[Think. Again.]

6. The inefficiency is still there no matter what the cause of it...

...either through heat energy lost in producing electricity from fossil fuels or from the Hydrogen fuel cell process.

So for the fossil fuel industry to be pushing the efficiency numbers of Hydrogen or any other non-CO2 energy production system is just a very, very weak argument. They are relying on the ignorance of the general public, and I find youtubers, like the one above who also do that, to be offensive and ridiculous.

Edit to add:

I do not consider Hydrogen produced with or from fossil fuels (such as in your statement:

"So to have a thermal (fossil fuel) power plant coupled with a hydrogen storage system, we have an overall efficiency of 41% * 32.4% = 13.3%. (And that doesn't include any power line losses) "

...to be a worthy method of producing Hydrogen, since our only reason to produce H2, and our overarching goal, is the elmination of the use of fossil fuels. Green Hydrogen (which does not use any fossil fuels at all) is the only thing anyone should be discussing.
