Cars, it's electric! Do Do Do

They are not pressurized and have very low mass. Also located in a place that is designed to absorb shock.

I think i'm having trouble with the amount of hydrogen required for a car. Need to do more research.
is it the size of a pancake compressor? or a large welding tank?

it would be really cool to just pull up and swap tanks (robotic of course)
maybe 1 minute? faster than refueling with petrol.
you wouldn't care how old the tank was (as long as it was still certified)
when i mention that with batteries people go nuts about swapping their pristine battery pack
for a tired one.

metals in a gas state just seem so wrong!

Who is going to build an infrastructure of 50 to 100K hydrogen fueling stations? How will hydrogen be transported from factories to these stations? How will the hydrogen be safely dispensed from trucks to storage tanks at said stations?

This is silly now that EVs continue to improve and all auto manufacturers are making them. Leave LH for rocket fuel - tho even SpaceX doesn't use it!

in all honesty it seems like the adaptations necessary to convert the existing gasoline/diesel distribution network would be reasonable, and its a setup that seems to run pretty well right now. The current electric grid cannot handle the load of so many EVs at this point and needs many upgrades, fast charging at a station (like a gas station) will certainly increase the load and needed upgrades, which option is cheaper i have no clue.

Reasonable is one thing - who's actually going to do it - and more importantly - why? What's the advantage - longer range? Issue(s) with charging times? Looks like that is getting faster:

Again, I don't know the volume needed.
How about they use a trailer, pull in with one and leave it, remove empty one?
Almost like they do it now, except the unload time would be cut to a 10th

The q is do they fill a tank in the car, or have a system that fills tanks for a swap? A robotic swap might even include home delivery. I'm calling Elon.

No tanks in the ground avoids a hazard that has been dealt with for years

I'm sure distribution is not the biggest obstacle.
Getting H out of coal might be higher. We got plenty of coal.

theres actually alot of activity on fuel cells for shipping/trucking, because of long charge times, especially for over the road type transport (they tend to run 2 drivers in a sleepr cab, truck never really stops moving) Fuel cells can be refilled in minutes not hours and have similar range per stop . . . . This may be a minor issue for most people on their own, but it is certainly an issue if you want to electrify shipping and logistics. also what about planes? they use more fuel and would be much better suited to fuel cells over batteries, you want to go back to slow prop planes for flying? me neither.

Because batteries still have a long way to go, i.e BEV's suck for many applications. Now is the time to push Fuel Cells and develop Hydrogen Electrolyzers utilizing renewable energy, and give us an alternative when the BEV's go bust.

The only application we are talking about here is personal automobiles. How do they "suck" now? And why would they ever "go bust"?

Here's another big advantage of BEVs vs FCEVs - homeowners can generate and safely store their own electricity to power their vehicles via solar and/or wind turbines. No one will be generating and storing their own H2.

Where does it say they are generating their own H2? It's completely off the grid with solar. There's a similar technology house I ride by in the sourlands on Snydertown rd but it's not that big.
 
Still need a battery buffering system in a fuel cell powered car. Just fewer of them.

Problem with local H generation is the CO2 sequestering. Easier to centralize.

Isn't a 1 size fits all either.

Says it in the description. I'm pretty sure I read somewhere that that house belongs to this guy's daughter:
