Glad to find this in the responses.

Air transport is quite possibly the best use case for hydrogen fuel that I can think of, and likely the only way we'll get sustainable air travel in the near future.

Wouldn't it be easier to just work on efficient synthesis of jet fuel? Then we could just keep the rest of the infrastructure the same.

Sometimes I wonder if that would end up being a solution for cars, too. It would certainly solve a few difficult edge cases that electrification will have a hard time overcoming.

Some synthetic fuel production processes require hydrogen, so a cheap hydrogen source would still be useful.
