What needs to happen for hydrogen fueled cars to ever gain traction

I know the price of hydrogen is 4 times that of gas. But will we ever have the tech to make it cheaper. Seems like a good alternative to straight electric cars as they get better range

Infrastructure to refuel reliably, cheaply, and safely.

What really needs to happen is battery tech needs to evolve by leaps and bounds to where we can have a compact, high charge and easily changeable battery packs.
Something akin to a propane tank exchange where you pull up, pay the fee, pull your old pack out, pull a fresh pack off the charger, plug it in and go.
Take all of 5 minutes. That or develop super fast charging.
And you have to make it cost efficient. And make sure the batteries and system don’t do more damage to the environment than ICEs

Stability.

First, all essential politicians have to have a way to line their pockets off of these deals
That’s the only way these types of things are set in motion
We can worry about logistics and common sense after they get paid

Hydrogen is great because it has a complete lifecycle with no loss. All hydrogen you use can be completely recycled. I'm a big fan but.....
Having said all that, unless we get the public release of low power hydrogen production, the power needed to create hydrogen fuel would probably be more efficiently used just powering cars directly.

Where do you think the H comes from? You see H typically hangs out with his pal C.

If our economy collapses because of high fuel costs in 2022, we can kiss alternative energy goodbye. No one will be able to afford it if we are all foraging for food.

No thanks

As a changeover once the engine is warm, sure. But you'll still need gasoline at the injection point with the ICE vehicles on the road today.

The problem with fuel cells is that you are using them to create electricity. So why not just use a battery, it's more efficient.
Fuel cells definitely have commercial uses and could work well for long haul trucks if the battery weight problem can't be solved but I don't see it ever happening for passenger cars.
I know there is a hydrogen combustion engine Toyota has been working on but who knows if that will ever be feasible.

Hydrogen ICE will never get any traction (except for special applications) for the simple fact that a tank of hydrogen run through a fuel cell to produce electricity to drive electric motors is about twice as efficient as burning that same tank of hydrogen in an ICE. I don't even think it's theoretically possible to improve ICE efficiency to match today's fuel cells.
Fuel cells have their applications, but I don't think passenger vehicles is it. It is difficult to transport and store hydrogen. Energy density by volume is not great.
I say it all the time, and I'll keep saying it until I'm proven wrong: the best use case for hydrogen is grid storage, produced by excess wind/solar that would otherwise be curtailed and wasted.

Happening now.
The future is likely H2 fuel cells for OTR and light duty truck applications and pure electric for commuter passenger cars. Battery electric is not the answer for any use other than commuter passenger cars.

Looks like 3 of 4 readers on this blog got their degree in European arts and family development
there is a couple basic laws of physics relating to conservation of mass and energy that the greenies did not take classes in, thus suffer in their dream development
Hydrogen molecules by themselves do not like to be stored. Its gravity, weight, is about 20 times less than propane and requires enormous pressure or container volume to carry a useful amount of energy.

It was actually a ultra flammable paint/ coating on the fabric that caused the Hindenburg fire, not the hydrogen gas.
