More Hype...
Many of you can Research LPG fires and explosions for mobile and fix operations... OHSA and Others publish many issues/problems w/ many of these systems...
Mobile like Fork Lifts to Propane Grills. Fix is Bulk Tanks for heating Homes etc.
Example: Even after CPSC etc make small tanks to have anti-overfill valve (Those 3 lobe knob valves on "20#" and other LPG "bottles.") you still have same problems.
Now many time more having fires and explosions use LPG CNG or Hydrogen in cars.
UK and EU and others already have problems w/ these because:
● Even when car are made/converted right, filling ports and hoses often have problems and leak.
● Tanks etc in the cars need inspection or fix often and cost money so many ignore or worse DIY a "fix."
● When these systems leak often is a Cryogenic problem and cold fuel can follow ground or lower areas a very long way before finding a heat source or spark and be a fuse to the leak. Same or Worse then Gas here when, not if, that happens. This is Why many people and states fight new LNG plants filling or emptying LNG ships. DE Fought NJ to stop one a few years ago because if a ship has problems can burn down whole towns and does not want to close I295 and Twin Bridge every time a ship arrives or leaves. All High Bridges are not make to close and huge problems every time does so.
Is a another thread w/ LPG etc tank leak and explosion here too. Not searching right now.
● Pressure Tanks have 5 to 10 years lifetime per DOT and other rules. Metal Tanks may extend lifetime but need recert and often need to pull tank out to hydro test them. Many will use fiber or carbon wound tanks w/ fix lifetime. Many will push this and leak or bust and by itself can be fatal even if doesn't explode.
Many "20#" LPG bottles you find at "locker swap" location are Illegal because 10 years past Cert date on unit but Locker operators are too cheap to check the date or to recert good ones. If you're caught transporting out of date tanks and anything it them, you should expect huge fines and even jail time.[This message has been edited by theogre (edited 01-29-2021).]

I've noticed quite a few times, that "Click for full size" does not work here at PFF, especially if the thumb sized object is an embedded imgur gif'.
but, IF, I right click on it, and chose 'open in a new tab' and view the full size in the new tab then he same new size will magically appear as intended back in it's appropriate PFF post.

Well, if that's true, it sure as heck won't get better with millions of non-tax paying vehicles running down the roads.
Interesting times we live in huh?

Honda already has the Clairity which uses hydrogen fuel cells similar to what is used currently in data center UPS batteries. Fills up in minutes. However filling stations are few and many more would be required.
My thoughts are similar to the TheOgre.
In the event of an accident (think Hindenburg).

You know the saying, "Get woke, go broke". Looks like GM plans to go broke... again.

Is same "green" crap as many others and been pushed for Decades.
CNG LPG and others are only good for Feet Operations that return to the "barn" after use. Like Many Utility companies have CNG vehicles for Decades because Nat Gas is at Wholesale or less $ and each car have own High Pressure feeds at the "office" to refill quick or overnight depending exact refilling method is used there. (Some Deliverer Co's use LPG etc now but many only for very local delivered in a city/town. Use gas/diesel elsewhere.)
These companies often have Training how to use and Safety Training as part of their job and records/video to show who did what when have a problem. And/Or Very tightly control exactly who connects the "pump" to the car.
You Don't want this in Normal Retail Channels w/ Many Idiots in just one day abusing the pump and rest of the equipment including whatever type nozzle.
Most have No Idea how many and how often the problems are at self service gas outlets because no-one reports spills etc unless maybe someone is hurt or killed. Even you Local news won't report most gas station fires or accidents. If covers them at all, most will get a "sound bite" story lasting maybe 1 paragraph. Most times when you Don't have a fire at a gas station is only because wind blows most fumes away and too lean to burn unless you spill a lot.

Could run an ICE w/ many compress/liquid gas types as well and again many Fleet have been going that for a long time. Fleets could easy run Fuel Cells too w/o much effort and likely some are doing just that.
In most accidents... Not All...
A good current DOT rated HP tank won't explode. Same w/ most HP tanks/"bottles" use by Mythbusters, DemolitionRanch, and others shooting HP tanks/bottles. DOT and Others have strict rules to cert any HP tanks to run a vehicle or just to transport them and been so for 50+ years.
Even "standard" spray cans seems "cheap" but must meet DOT rules and other standards to ship to a store or you.
But LPG CNG H2 and others leaking can burn or explode. If a HP leak is burning can be hard to control until fuel is gone. Even then is Not like Hindenburg and others most times.
It's when you put anything in the Retail Channels and Millions of fools get their hand on them and doesn't do proper maintenance you often have the Worse problems like LPG cars exploding often in EU etc. on YT and others. Anyone staying they can make H2 Safe and Fool Proof is Lying or a complete moron. Just follow news or better read OHSA NTSB etc Reports for people dying using or just being near by Low Pressure Propane and Nat Gas. NYS and City have some of the best Fire Codes yet still have same problems as rest of US w/ Exploding Building for both fuels. Just saw another building NG exploded yesterday but don't know where.
I stopped counting Decades ago how many times I see people fill cars w/ gas while Smoking, Car is Running and more. Is only luck you don't see a lot more people burn alive filling a car.
