its that extracting it from anything uses energy, and we dont have any clean base source for this

China has started to develop sources, part of a multi-year plan.

Cool video. I agree using solar energy is currently the best source of energy for electrolysis, but while hydrogen itself is clean, the production of solar panels is not as perfectly sustainable and harmless as people would like to think, although I agree its preferable to carbon emitting fuels or even the lithium needed for batteries. I think this is more of a 'best we can do with what we have now' plan than a 'problem solved, no more energy environmental issues' thing
