Are they restricting battery vehicles that catch on fire???
Here’s the actual video, if you don’t wanna go thru all the click bait on the posted site.

“ Hydrogen tanks are fireproofed”
Nothing is fire proof. Fire resistant for a specific period of time, yes. But fireproof? No.

Battery exchanges are a ridiculous idea. Gas stations fuel hundreds of cars a day. It is not feasible to support the infrastructure to charge those hundreds of batteries. Never mind that batteries are very heavy and doing a quick swap would be extremely unlikely. And don’t forget that battery swaps would require standardization across the entire US fleet of EVs.
Imagine having an EV in Florida and trying to evacuate. Or having to find a working charging station.
Propane is heavier than air, I would imagine that is the reason for the restrictions.
The propane (if there are any leaks) would collect in the lower parts of the tunnel and be an explosion hazard.
Hydrogen is lighter than air and should just float away through the tunnel vents or the open ends.
"Then there’s the infrastructure problem. How do you safely stored transport, and deliver hundreds of millions of cubic feet of the stuff to all 50 States?"
All those problems have already been solved. The USA uses 100 million metric tons of gaseous hydrogen every year.
Imagine trying to fight a war after fossil fuels are outlawed. I can’t.
Get educated
Yes, you are right. Sloppy on my part.
When the USA gets serious about using nuclear power. That is beginning to happen as people realize that solar and windmills are not going to cut it. I saw a recent article that Dow Chemical and a reactor company were doing a joint venture to produce small modular fission reactors to power industrial plants. The reactor is an 80MW helium-cooled pebble bed. I would prefer molten salt reactors, but I am good with the proposed tech.
I’ve read that’s why the ChiComs are switching their civilians to electric cars (charged by coal burning power plants). Conserving petroleum for military use.
Totally true. For range and heavy loads, you need a hybrid or a bog standard petrol/diesel.
My new car’s a hybrid - 1.6l petrol.
Flick a switch on the center console to put it in sport mode, and it prioritises the battery. Ye gods, is it fast.
I did a comparison on a test drive - same make and model, both new, 2.2l diesel vs 1.6l petrol (gas) hybrid.
The hybrid did 0 to 60 in less than 8 seconds... in economy mode. The 2.2l diesel version took just over 12 seconds.
Fuel economy at 55mph... 36mpg on the diesel, against 52mpg in the hybrid. With diesel costing quite a bit more than gas, it’ll cost half as much to fill the tank and get the same range.
Whacked it into sports mode to see how fast it could accelerate off battery, and it did 0 to 30 in 3 seconds. Without touching more than a thimble-ful of gas.
Are batteries heavier than air causing a tunnel to become a potential bomb?
Hydrogen is coming just after commercial fusion power
Think Florida..Think trying to evacuate in these electric vehicles especially when the power grids is down
My bad...it is "only" 10 million metric tons...should have checked first. Still sufficient to prove the practicality of large scale hydrogen use.
Hybrids make sense, especially if they have a built in charger that you can plug in over night into your home 220 volt line here. USA voltage. The Prius has a shrimpy 94HP engine but the newer models can run that engine and the electric motors at the same time if need be. On the highways most likely. To accelerate.
EVs..... only good as a family
s second automobile.
“ The USA uses 100 million metric tons of gaseous hydrogen every year”
How big does a tank of gaseous hydrogen have to be to equal the thermal energy in a 20 gallon tank of gasoline? And can I get a fill up at thousands upon thousands of stations from coast to coast 24-7-365?

nice dishonest answer. Propane can be stored safely as a liquid at room temperature as long as the pressure is around 150 psi. Hydrogen cannot be liquified above its critical point of 33K. To be liquid at atmospheric pressure hydrogen needs to be cooled BELOW -423F. So for hydrogen to be used as a fuel (like on the space shuttle) you need a very expensive cryogenic storage tank, but no matter how good the tank heat will leak in and convert your hydrogen to gas. You park your diesel truck for a month with 20 gallons in it and when you come back you still have 20 gallons in it. you park your hydrogen fueled vehicle for a month and your tank will be empty when you come back
