Energy experts say U.S. policy must direct money to industries that really need clean hydrogen — and away from those that are better off using clean electricity.

This is not a bad way to prioritize:
I'm sorry, are we really going to pretend long haul flights will become hydrogen in the near future? Has any airport begun building, or even thinking of, refueling infrastructure?
No; it's a fairly distant thing with there being some aircraft design happening.
It's not a "next tuesday thing"
Ammonia, steel, and some petrochemicals could be moved much sooner.
I'm curious why long-haul aviation is easier than short-haul aviation according to this chart. Why would that be the case?
Short-haul can hopefully be handled by improved battery tech. Long-haul would need even lighter batteries so it's less likely to work or will take longer.
Ah, makes sense! Glad to hear that battery tech is approaching the level where short-haul aviation is viable.
