What Drives This Madness on Hydrogen?

I don't agree with the sentiment that the experts have written off hydrogen. Actually I had a lot I'd say on that but it would come off as completely snarky.

While hydrogen and electric via battery storage will form a large part of the path ahead, especially in urban and industrial sectors, there are other paths which haven't got much light. For one, certain interests keep prodding bio fuels ... while the oil industry keeps very very quiet that the fuel crackers in their refineries could utilise ordinary renewable organic based oils as a feed stock to produce the same as presently used in vehicles.

Green hydrogen certainly will be a product of huge demand in the future, based on what I've read the last couple years ... the smart money is on anhydrous ammonia, for which its production requires a lot of hydrogen. However I guess why this sector is attracting so much interest, if there's a better path than ammonia as a means to utilise hydrogen, those successful will reap the rewards.

They are already trialling using ammonia as a fuel for the same large engines found in cargo ships. [1] Fuel cells installations using ammonia already exist [2]

Even without all those folks whose financial futures depends on them refusing to understand that hydrogen is bunk - my guess is that hydrogen would still have billions of True Believers. There seems to be a profound mythical/religious aura around it - "magically pure, as natural as the sun, creates only pure carbon-free water when it burns...". The stuff pushes far too many emotional buttons in a lot of people, and seems to have gotten incorporated into America's culture wars.
