Well in theory, it could come from nuclear. That’d be cleaner than fossil fuels.
It uses electrolysis, so may as well cut out the middleman and just use electricity to power things without losing efficiency to convert it.
Well the only reason to use it would be in electric trucks and busses. The main benefit of the hydrogen cell is being able to swap cells instead of waiting for a recharge, which is only needed for vehicles that need to keep a strict time schedule. The cells can be charged at truck stops and bus stations that can be fed by the power grid using nuclear energy, or by solar/wind if it’s a remote location, or a combination of the 3.
Hydrogen cell is not a bad technology, just like all energy solutions (expect fossil fuels) they have their strengths, weaknesses and best use cases. There’s no reason why we couldn’t use each one where they’re the strongest. We don’t need to pick just one as an end all be all.
