Hydrogen sucks for cars. It kinda sucks for trains - battery-electric probably still makes more sense. But for jets, hydrogen could be a real winner. So, on that front, we have now tested hydrogen jets:

Also it doesn't entirely matter that most of the hydrogen comes from cracking petrochemicals presently. Of course it's not ideal but you need the infrastructure in place to transition into green hydrogen as production picks up. You also need someone using hydrogen to justify investing in green hydrogen.
