Generally, Hydrogen for transportation (no infrastructure) makes little
sense compared to EV’s (everyone has an outlet in their garage). The
business model for hydrogen cars is very weak (though it is needed for
trucks and road warriors).
BUT!
There is a future for hydrogen in utility scale applications for the
eventual Bazgigawatts of periodic solar and wind excess into electrolysis
of water to hydrogen. Think of it as energy storage (the holy grail of
renewables).
But then creating a HUGE infrastructure from zero to distribute this
hydrogen source in tiny little buckets to burn everywhere in tiny amounts
in millions of cars makes no sense, when the utilities can far, far more
easily burn it right there at their plants to provide a continuum of
electricity at night and/or low wind.
Another way to look at it is to have the utilities burn the excess hydrogen
to make electricity and use the grid to distribute that electricity to
EV’s. That is a far easier way to distribute “hydrogen stored energy”
since EV’s and the grid distribution already exist everywhere.
Of course, there will always be a market for SOME hydrogen fueled cars and
trucks that must do long trips or continuous road travel. No question.
But that is something like only 10% or our transportation energy… and easy
to implement along the interstates…
P.S. There is another thing I just became aware of. Other countries
versus the US with respect to Energy Storage.. Not everything is equal.
Germany has a different perspective on storage (hydrogen) for many
reasons… they have no natural gas like we do. They cannot use natural
gas plants to make-up solar/wind shortages. Where we view “storage” as a
short-term (max 12 hour overnight) need, they view storage as a long-term
requirement and not just for backup electricity, but for weeks or months…

Just some thoughts.

I saw an article last week about a couple of scientists who thought
hydrogen could be transported much more easily as ammonia (NH3). They
have suposedly discovered a method to convert ammonia to hydrogen with
out using catalysts and with good efficiency. I can not find the
article now but sounded like a game changer - if true.
