The issue for hydrogen right now is the cost of green hydrogen. No one wants to use green hydrogen if it’s more expensive than gas, since a HFCEV costs more than an ICE vehicle. And there’s no point to grey hydrogen since it’s dirty and harder to transport than oil. Once we have green hydrogen at parity with fossil fuels, then you’ll start to see some changes, bot before then.

Correct. Hydrogen will become a thing once we have excess electricity, maybe from solar, or maybe that high temperature reactor prototype will eventually fly off. But we are looking at a decade or so until it could become viable and widespread. Sure pioneers and prototypes are welcome in the meantime.

Hydrogen is fueled as ammonia. EV's are aimed at consumer level vehicles and short trip vehicles. Without huge breakthroughs in charging, capacity, and weight reduction, battery powered will not be suitable for anything long haul like big ships, trains, planes, and semi trucks. The vehicle landscape will look very different in 5 years

As far as I am aware, ammonia production uses hydrogen as a reactant. Meaning that the cost of green hydrogen is relevant to ammonia being used as an energy source.

I don't know what that has to do with what I said. I said EV's aren't a solution to big business or big shipping, and you went all in on one sentence, ignoring the point of the post. You said no one wants to use green hydrogen, and I said the biggest companies in the world are actively researching how they can utilize hydrogen fuel instead of batteries. I guess "no one" didn't include companies like Caterpillar, Amtrak, Boeing, GE, and Toyota/BMW?

Edit: of course you downvote me because you disagree. You don't understand that the arrows are meant to encourage discussion, not silence dissenting opinions. On the note of opinions, I am a chemical engineer for DOW, working on alternative fuels. I can tell you with absolute certainty that your opinion is wrong. Uniformed at the best, and willfully ignorant at worst.

The production of ammonia, whether you believe it to be "green" or not, is far less damaging to the environment than mining precious metals. The industry already has solutions that I can't openly discuss, but if you read anything beyond Elon Musk's tweets you'd know BP and FS are building their ammonia pipelines as we speak because hydrogen, not batteries, is the future

Those companies are mostly using grey and blue hydrogen, because it’s 𝗰𝘂𝗿𝗿𝗲𝗻𝘁𝗹𝘆 much more cost effective.

You mentioned ammonia and I responded that ammonia production usually requires you to produce hydrogen first.
