You said that we aren’t using hydrogen as a fuel source, which is patently false. You must think we’re burning those hydrogenless hydrocarbons that so famously exist. It’s not in the form that you like, but we’re literally using copious amounts of hydrogen as a fuel source and have been for decades. It isn’t suddenly not hydrogen because it’s attached to carbon when we choose to burn it. Plain elemental hydrogen doesn’t exist in abundance in any capacity that we’re capable of harnessing, which is why you have to bring up methods to create it even when it’s the most abundant element in the universe. You’re the one who chose to respond to me, in my comment about its use in cars, in response to someone else’s comment about hydrogen in cars, in a thread about cars and somehow I’m the one who’s changing the topic?

How are we sustainably converting elemental hydrogen into a state where it’s readily storable and transportable for use in vehicles? I’m not pushing against it as a viable energy source generally speaking, but it really doesn’t need to be in a car, where it’s used to power an electric motor in the exact same way as a battery is, except the battery can recapture energy through regenerative breaking. I was pushing back against the implication that humanity is stupid for not using hydrogen in general, because we use a lot of it.

For the record, your all-powerful and flawless elemental hydrogen can power the grid just as readily as it could power a car. It’d be great if it were a larger share of our energy generation, for the record.

I’m definitely open to being wrong about the world’s impression of hydrogen fuel cell vehicles, but I’m not sure it’s borne out in the data. Europe doesn’t seem to be adapting it anywhere near the rate at which they’ve adopted BEVs (I couldn’t find a 2025 report in my cursory search, but would love to see one if anyone else finds it), nor does China, which is all in on BEVs. In fact, it seems like California may have more hydrogen fuel cell vehicles alone than all of Europe combined. That’s two of the major markets accounted for, but it might be possible to convince the US to adopt hydrogen when they decide they no longer want to be left in the past.

I’m not sure the infrastructure build out for hydrogen is directly comparable to the charging infrastructure for BEVs. At least some segment of the population has access to charging infrastructure just by virtue of having access to an outlet at their homes, which allows for trickle charging, as well as the option to install a dedicated charger at home that allows for much cheaper charging that’s also fast enough to charge from 0-100 overnight, so no need to stop at a fuel station at all. This meant that there were people who were willing to adopt the technology through the growing pains. With hydrogen, you run into a bit of a chicken and the egg problem where companies aren’t encouraged to expand infrastructure without adoption rates being high enough and consumers aren’t itching to purchase a vehicle where fuel is more expensive and less convenient to access. The refuel card incentives were supposed to get consumers over that hump, but it doesn’t seem like it was anywhere near enough. I think the conditions were ripe for an emergent technology to eventually replace ICE vehicles, but hydrogen fueled vehicles were on the back foot to begin with.

Hydrogen is a major fuel source, just not in the form that’s necessary to power hydrogen fuel cell cars. Regular gas vehicles are powered by hydrogen, since they’re a component of gasoline. Any energy generated by liquified natural gas (though I hate the term) is using hydrogen as a fuel source. It’s not exactly easy to create, liquify, store, and transport pure elemental hydrogen for use in hydrogen fuel cell cars, let alone the cost to develop all the infrastructure to do so. I don’t think it’s a collective action problem, and if we were going to rally around a singular transportation issue, I think it’d be far more valuable to demand robust public transit options.

In the US at least, I really don’t see hydrogen ever taking off. Even in California, there’s so few stations that you can’t really travel from the top of the state to the bottom without going out of your way. The hydrogen fuel stations that are in place are even more expensive than they were a few years ago, if they’re still functioning at all. We’re talking like $180 USD for the equivalent of a tank of gas, at stations that aren’t as convenient as a gas station or an outlet at home. It’s even the subject of a lawsuit, which may or may not be successful.

It seems like hydrogen has already lost the race for the rest of the world, with BEV adoption growing substantially in Europe and China. Personally I wouldn’t want my market to rely on solely Japan and a US headed by someone blatantly antagonistic to alternative fuels.
