Hydrogen is much lighter though. You wind up with big ugly planes that are lighter than the planes we have now. Apparently they’ll be able to use shorter runways as well.

You're forgetting the tank. There are a few hydrogen powered cars on the road, their tank weights about 125kg and stores a whopping 5kg of hydrogen.
