And to think no mining of rear earth minerals.

The reasons should be clear from my comment. The infrastructure required for EV charging stations is a problem. To charge multiple cars takes real estate that’s tied up for 20-30 minutes at a time. That same real estate can handle many more cars in the same time frame with gas pumps, (or hydrogen). And as someone traveling that time really adds up on a long trip. While it takes more energy in electricity to produce the hydrogen the benefits of fuel cells still make it worthwhile. The production costs can also be mitigated by using sustainable means to generate the electricity, (solar, wind, etc). And since it can be produced anywhere there’s no need for refineries near ports and pipelines that are a potential ecological disaster.

Yup.

Are you suggesting that each service station generate its own hydrogen, or that it be piped to it or distributed as we do gasoline?

Here’s an interesting site I found on Hydrogen/fuel cell technology and implementation: https://www.ieafuelcell.com/index.php?id=33

Currently in California, which has hydrogen filling stations, there are both stations with their own electrolyzers and those where tanks are dropped of by trucks.

I too am afraid to use the traditional Lithium batteries due to fire risk. I have them in numerous drones and eBikes.
There are newer chemistries that are not as energy dense (heavier), so they don't make much sense yet in aviation.
The current chemistry which is much less prone to fires contains Iron ( lifepo4 or LFP). They make sense in homes where weight isn't an issue. They are also popular in RV and boat use, where a little extra weight is worth the reduction in fire risk and the recharging cycles are in the thousands. Golf carts used lead acid batteries which could be recharged 300-500 times and may last 3-5 years. The newer safer batteries cost more but last much longer, so are a better value. Tesla is already using these safer batteries in some models but they or their battery suppliers already have a large investment in the factories to produce the lighter weight chemistries. In a few years most EV cars will have safer batteries. I also have a fear of sharks although I hear that cows kill more people. At least they don't eat us.

Don't wast your money, hydrogen in 3-5 years will be the norm.

And we'll have fusion power commercially viable in 20 years (that time estimate has been the same since around 1960).

It doesn't matter what the vehicle power source switches to. It will be several decades before it's the norm.

And, IMHO, the future of hydrogen is in fuel cells, not ICE. Fuel cells are not ready for prime time.

No, fuel cell doesn't make it you burn the H2 in a combustion and go!

That works but doesn't solve the NOx pollution problem

It's not a problem, never was never will be.
