Hey, Jim,
Have a look at this video:

You've probably heard something about hydrogen. You may know hydrogen
can be used to fuel vehicles, but did you know that clean, abundant
hydrogen is used safely all around you every day? "Hydrogen: Nature's
Fuel" shows hydrogen at work in warehouses, golf courses, and even
breweries. The hydrogen used in these applications is made in a variety
of ways from domestic sources. Hydrogen truly is nature's fuel. With
hydrogen, we have the opportunity to create our own clean energy future.
In particular this part: https://youtu.be/Poy26bvSfS4?si=_DQjroWvWf_MWOcf&t=1973
What is your professional opinion about the potential for H2 fueling the future?

You mean other than it is very expensive, difficult to store and
transport, and when burned in air creates huge amounts of NOx?
"Hydrogen truly is nature's fuel." is childish dreck.
While hydrogen in quanties sufficient to be mined have SUPPOSEDLY
been discovered, it remains to be seen if that will ever happen.
Methane, uranium, oil, coal etc. are ALL "nature's fuel".
H2O cycle is its fundamental simplicity. And, if the waste heat can beput to productive use, as in the brewery example, H2 production efficiency
Jim,
Thank you for taking the time to view and analyze the video and offering
your valuable critique.
With the current price of solar panels at less than a dollar per Watt, I don't see the cost of the energy to produce hydrogen as a significant barrier, as solar could power a 70?80% efficient electrolyzer for decades
(during sunny weather, of course). There is also https://newatlas.com/energy/aluminum-gallium-hydrogen-powder/ . And, although the methane reforming method of H2 production produces CO2 (an arguably objectionable byproduct), in the brewery use-case, that CO2 was actually captured and sold. The fact that methane is almost universally available in urban environments does make it a viable consideration as a source for H2 in specific cases.
The difficulty in storage of electricity is the heart of the issue. And, not surprisingly, H2 does have storage issues, however I don't seem them as insurmountable.
LH2 can be held at ambient pressure in a Dewar for a
considerable tens of days without significant loss. Pressurized H2 is shown to be routinely stored in steel tanks, so embrittlement seems to have been addressed. (Unfortunately, even graphene fails to contain it.) And, solid-state H2 storage appears to be viable, and is currently being developed, only requiring warming to be released. So, progress is being
made in the storage of H2.
The difficulty of transportation of H2 by tanker truck appears to be similar to gasoline. But, unlike petroleum-base fuels, H2 can be created at the point of use, so no transport is necessary.
Personally, I don't advocate burning H2, not only because of the production of NOx (bad stuff, requiring expensive catalytic-converters on current internal-combustion engines), but because of the inherent poor efficiency (20-30%). Rather, I see fuel-cell technology as far preferable, but currently, with some problems in efficiency and maintenance (electrode-degradation contamination of electrolyte, etc).
I view the "Hydrogen truly is nature's fuel." statement as somewhat valid from a quantum physics standpoint. For me, the beauty of the H2O -> H2 +O
H2O cycle is its fundamental simplicity. And, if the waste heat can beput to productive use, as in the brewery example, H2 production efficiency can apparently be doubled. My thinking is that, burning any fuel in atmospheric air is objectionable, because Earth's biosphere (upon which all life shares and depends) is a closed system, and fundamentally
unsustainable. As a professional engineered, I'm sure you understand that. In that light, I believe the current failure to capture the electrolyzed O2 is wasteful...
Although the documentary showed H2/air fuel-cells being routinely used indoors, I have a bit of trepidation in the potential for an explosion in
the event of a H2 leak; but that can be addressed (with some added expense).
Your statement indicating that hydrogen in quantities sufficient to be mined have SUPPOSEDLY been discovered, is news to me. Was that stated in the video? It seems unlikely that such a molecularly light gas could be contained to any significant extent naturally/geologically.
The current burgeoning development of H2 as the "fuel of the future" by so many reputable firms (Rolls Royce, Airbus, ...) leads me to believe that their engineers's analysis has shown it to be worth the R&D expense at
least.
We are truly fortunate to live in a time of such explosive (excuse the pun) technologic revolution. Now, if only the political arena (and humankind's baser instincts) could evolve out of the dark-ages ...
