The problem is weight. The heavier the load the bigger the gas bag needs to be to carry that load. The whole thing very quickly gets out of proportion and considering they were using hydrogen the heavier the load the riskier it was.
Modern airships are helium-based, but helium is way too expensive to ever be commercially viable on a large scale.
You don’t use up the hydrogen in operation, so you don’t need to create it on the vehicle. Attempting to do so would just add weight and probably wouldn’t work anyway as I suspect the amount of energy you would require to convert water into hydrogen is a lot more than a few solar panels could ever provide.
The issue is hydrogen is just inherently dangerous. Compounded by the fact that no one really cares anyway because airships don’t have a purpose to exist in the modern world outside of a very few niche scenarios.

Just go back to using hydrogen. It’ll be a blast!
Some solar panels on top of the balloon, nowadays you can even create your H on the go from the H2O in the air!
