What ever happened to hydrogen powered cars?

I am watching an old episode of Top Gear and they have a hydrogen powered car from 20+ years ago. Why did this not happen?

Infrastructure is a big issue.
Toyota makes them and you can buy them in California.

Govt doesnt want that
Lithium EVs or gtfo

No infrastructure, safety? Want a bunch of knuckleheads refilling hydrogen.
Ohio State had a hydrogen fuel cell bus on campus back in 2016 or 17.

A hydrogen fuel cell car? It's really a battery-powered car and the hydrogen fuel cell recharges the battery. Honda makes some.

Just saw a test flight of a hydrogen powered jet the other day on line.

Market is still pretty amall. More of an Euro/British thing right now. BP is really pushing forward in the market.
Ineos is building a H2 version of their new vehicle.

Chinese bribed our politicians into mining lithium for EV, therefore that's why politicians write laws favoring EVs.

Big Windmill/Solar/EV/Oil/Nuclear/Coal/Steam/Desalination killed it through Dukakis, Clinton, Obama and Biden. I'm pretty sure I read that on the Daily Mail.

look into "plug power" symbol PLUG
they are doing it for commercial vehicles and machinery
trouble is, hydrogen can go boom like a bomb, so many people still fear it.

Hydrogen-powered vehicles use lithium batteries. The problem with cars is that they don't need to refuel enough. The attraction of a battery fuel cell vehicle is one that needs constant refueling. People take their cars from home to work for the most part. It's big rigs, planes and forklifts where the benefit of the H2 technology makes it worth it.

Lithium isn't even the predominant material used in EV batteries

Those knuckleheads are currently refilling gasoline. Is hydrogen that much worse?

One thing the government doesn’t want is ease of mobility.
Zero motivation to have quick charging batteries.

in terms of degree of boom, yes

Saw one of those Challengers the other day that ran on water. He walked through the whole set up and I’m still skeptical

Do you think they're going to ban solid state batteries?

We can’t keep our natural gas network together. Switching to hydrogen would be catastrophic.

Yes.
As for OP’s question - outside of the potential safety concerns, the other big issue is infrastructure. A major shift to hydrogen power (whether via fuel cells or direct combustion) requires a way to get all of that hydrogen to consumers.
While hydrogen has a high energy density by mass, it has a much lower energy density by volume than gasoline. So it takes something like 3.5 gallons of liquid hydrogen to produce the same amount of energy as 1 gallon of gasoline. A fair amount of this is theoretically offset by the efficiency difference between fuel cells and ICEs, but then you still have the problem of needing to liquify hydrogen and transport it in liquid form.
On top of all of that, hydrogen is notoriously leaky. Being the smallest molecule, it can escape from containers that would otherwise be airtight.
So when you think about all of the infrastructure changes/additions that would be required, hydrogen starts to become impractical as a primary fuel source/energy carrier. Our electric grid may not be suitable for full-scale EV adoption yet but it’s way closer than any hydrogen equivalent.
Because of all of this, most of the focus around hydrogen / fuel cells has shifted to ammonia. The idea is that ammonia is much easier to transport (albeit with its own hazards), has higher volumetric energy density than liquid hydrogen, and can be either used directly in fuel cells or converted to hydrogen at the point of use. There are folks who believe strongly that the future will be an “ammonia economy” but it’s still a long way off.
