Don't know about you guys but I have less than zero interest in having a large tank pressurized to about 2000psi in the vehicle.

I think it is closer to 10,000 lbs I saw 2 pumps that dispersed 5000 or 10,000 psi ,the tanks look like fiberglass but are metal I was told

I don't think anyone here is suggesting hydrogen has greater than zero chance of widespread adoption. Batteries is a done deal. Within the next two years there will be many dozens of models on the market. Virtually all existing automakers are in and there are quite a few new companies introducing new models as well. The charging infrastructure is ramping up much faster and in a couple years there will be plenty of choices along the main intercity highway systems

EV's to me are not the answer for our environment, the waste from Lithium batteries are already classified as hazardous under EPA recovery act,then the mining of Lithium is nasty and uses millions gals of water just to evaporate into the air. When the brine wells dry up they will be pumping from the ocean, A storm came through last night and knocked the power out and when I went to Napa today there was still at least 20 waiting on a charge ,me I am not buying into the EV's for clean energy

One teeny-weeny tiny little snag with hydrogen:  it takes more energy to produce it than it gives out, i.e. there's a net energy loss with it.   Even though it's the universe's most abundant element, it doesn't occur naturally on this planet, so it has to be made from something else, like petroleum or natural gas...   If you factor in all the costs, it's obviously no more than a snake-oil scam for the gullible to get excited over.   At best, all it does is exchange the pollution from one place to another, just like EVs and E-bikes and all the other E-nonsense out there now.   None of this will "save the planet".   We're screwed, big time.   We're the only species on this planet that shits in its own nest.

Here's the problem with EV's Yoda...

Some older members here may remember ads on TV showing natural gas back in 70's saying and showing the flame going out in a few years.Working for Tennesse Gas (Tenneco) we had 1000's of miles of 30 to 42 inch pipe across the USA pumping 24 hours a day, Dilling 20 gas wells a year and capping those wells with some @ 15.000 psi at the well head,I would lMAO ,a lot of people really believed that crap though and rushed to convert their homes to electric, that old flame is burning diesel fuel and gasoline are not going away anytime soon

Scientists Find a Simple Way to Produce Hydrogen From Water at Room Temperature
PHYSICS31 August 2022
ByDAVID NIELD
An aluminum-gallium alloy reacting with water in a test tube
Bubbles of hydrogen gas are generated from the reaction of water with an aluminum-gallium composite. (Amberchan et al., Applied Nano Materials, 2022)
Hydrogen fuel promises to be a clean and abundant source of energy in the future – as long as scientists can figure out ways to produce it practically and cheaply, and without fossil fuels A new study provides us with another promising step in that direction, provided you can make use of existing supplies of post-consumer aluminum and gallium.In the new research, scientists describe a relatively simple method involving aluminum nanoparticles that are able to strip the oxygen from water molecules and leave hydrogen gas.
The process yields large amounts of hydrogen, and it all works at room temperature.

That removes one of the big barriers to hydrogen fuel production: the large amounts of power required to produce it using existing methods.

This technique works with any kind of water, too, including wastewater and ocean water.

"We don't need any energy input, and it bubbles hydrogen like crazy," says materials scientist Scott Oliver from the University of California, Santa Cruz...

la batteries have been producing hydrogen gas for years. now to collect, compress, and burn in engine.
Galium,another mineral that may not exist in necessary quantity to produce the amount of hydrogen we will require.

Sounds really good but what are they leaving out? You don't get something for nothing. There has to be a cost involved in breaking that oxygen/hydrogen bond and it has to be paid in some way. What they aren't saying is how? Oh sure just use a catalyst. Code word for Magic? Well it's not and they aren't explaining how it is doing the impossible. Catalyst science is old and well known. It does not violate the fundamental laws of physics I do not think. So how is this possible, and where are the scales being balanced? That's what I want to know.

Harness the power of methane gas in a human fart problem solved,technogly in EV's and Hydrogen will advance in the coming years IMO ,I am in no hurry to rush and buy either

Remember Cold Fusion? The answer to the energy problem.

[Lin]

We know what works right now. Fossil fuels work, so do EV's.  Each may have limitations but have many happy users.  Hydrogen as a fuel or for a fuel cell also works, but is not yet in widespread use.  That does not mean, however, that they never will be.  Given time, cheap production will become possible.  It is reasonable to assume that there will be some downsides just as there is to other options, but it can become an alternative.  Even cold fusion will probably happen one day.  I don't know when, but I would not bet against it.

There is a similarity to hydrogen combustion engine fuel to CNG and propane fueled engines, which are common throughout the world.  Whether the hydrogen engines power by direct combustion propulsion to drive or hydrogen/electric propulsion, the adaption time will be quicker because of the similarities. Cars, Pickups and commercial vehicles are already on the road, some manufactured by major vehicle manufacturers like Toyota, Honda, Mitsubishi, Volvo and Daimler to name a few.
It took Clear Energy just a few years to build CNG filling stations throughout America. I think that is the model, manufacturers are encouraging start up hydrogen filling stations companies to build.
Then there is the tesla effect.
  Existing manufacturers don't want to be one upped again, as happened with ECars. They are looking for alternatives, Chevy had hydrogen/electric prototypes running around several years ago.
