We can call hydrogen a source or a transport, but it is just semantics. If we call green hydrogen a transport then oil is also a transport, and if oil is a source then green hydro is also a source. It takes more energy to create oil, gas or hydropower than we get out of it as well. Most of our energy sources are just stored solar energy that would otherwise have gone to waste. The idea with green hydrogen is the same, create hydrogen from energy that would otherwise go to waste. One can argue that hydrogen isn't the most efficient storage mechanism, but I don't understand why it should be dismissed as a source separately from all other storage mechanisms.
