Hydrogen cars can usually safely vent their fuel. Even inside a garage venting hydrogen likely won't burn long or hot enough to set anything on fire; car and home very likely to survive. Contrast that with an EV blowing its top where car will definitely not survive and house likely won't either.
I know, I know; but you have to make that comment when this kind of thing comes up, it's the law.
Also, yes, the difficulty with hydrogen isn't the hydrogen per se, it's the additional requirements around storage. Hydrogen's very hard on storage vessels, not purely in most things being leaky as far as hydrogen's concerned, but also in embrittling whatever storage vessel you use.
Unitednuclear pioneered an interesting system where hydrogen was stored as a metal hydride that would release the gas when the metal was heated. It lost some energy efficiency due to needing power for the heater, but it allowed enough hydrogen to be stored in an ordinary vehicle to equal 15 gallons of gasoline.
It may not be energy efficient, but gray hydrogen is cheap in the United States because you can manufacture it from natural gas and we are the Saudi Arabia of natural gas. In theory we're talking like a thousand years of the equivalent of sub 2 dollar gas (and that is including compression and all the other extra costs). Unfortunately shitty energy policy undermines that.
I know hydrogen is currently much worse than batteries but if the same resources had been put into hydrogen that may not be the case.
You can just stick some electrodes into water - doesn't even have to be clean water - and make it that way.
One of the less farcical plans for clean power is a shit-ton of nuclear plants (fusion or fission, doesn't affect the plan) running electrolysis all day every day to generate the hydrogen needed to replace fossil fuels.

I'm surprised the makers of Rise of Skywalker didn't invoke this as a troll response to people who question how Palpatine survived.

There may also be the threat of committing suicide after creating a car that works with hydrogen fuel cells that is reliable and cheaper than gas/oil.
The problem is that sourcing hydrogen isn't energy efficient.
