In 2022 there were, count 'em: 250 hydrogen filling stations in China!
OH MY GOD!!!!!!!!! WE'RE WAY BEHIND.
This surely an international threat to the United States, having only 54 hydrogen stations and, 127,588 gas stations in a country of car cultists who don't give a fuck about climate change, but love to sell bourgeois fantasies about ways to waste money and energy.
No amount of marketing can make hydrogen "clean," and to the extent this rather tiresome fantasy has prevailed since the 1970's it's more of doing nothing other than participate in a dangerous fossil fuel shell game.
There is no sense of decency, none, for those selling the hydrogen fossil fuel wasting shell game.
None.

The technical term, for people who think, for the devices utilized by people who obviously can't think, is the term for this logical fallacy:
Appeal to Authority.
I like Secretary Granholm, particularly for her support of nuclear energy, a form of
primary energy. Nevertheless, she has no training as a scientist having earned degrees in Political Science, minoring in French, followed by a law degree.
Therefore she has to rely on scientists to give her advice.
She obviously seems to need some better scientific advisors in some of her programs. What is being sold to her is poorly advised, because hydrogen is a very, very, very dirty fuel, and trying to make it into a consumer product will make it dirtier, if only for the energy expended to compress it after
wasting energy to make it.
No amount of cheap marketing by cheap marketeers can change that
fact.
Facts matter.
