Not so great news for Tesla

Politicians kept banging on about hydrogen in the UK simply because we had little investment in batteries/EVs and they needed to cling to something as an alternative to cover up the fact that they didn't really have a coherent plan.

The main reason politicians banged on about hydrogen was because they were being lobbied by the oil and gas industry, as most hydrogen is produced by steam reformation of methane.

Hydrogen would never really work for planes - the energy density is nowhere near high enough, so a plane would have to carry far more weight in liquid hydrogen than it currently does in Avgas to achieve the same flying times/distances.

I was being generous, but you are right that there are still problems, just as there are with current batteries - although 400-500Wh/kg batteries are now appearing which would make smaller GA planes and light turboprop replacements viable.
