I have not studied Hydrogen too much, curious question for those who know more about this than I. Do they obtain the Hydrogen from (maybe electrolysis of) water? or is it from another source?

It's a central part of the H2 debate- where do you get the hydrogen. There's green - from electrolysis, blue - from SMR with carbon capture and grey H2 - just SMR. Many experts say green H2 can be cost comparable to grey maybe by 2030. I think sooner possibly.

On scale how many kilotons of Methane will they need per...say day/month to supply a nation of hydrogen cars? It seems a bit of diminishing returns to use hydrocarbons for hydrogen. Water, Hmmmm....we have a lot of it, but it is a necessity of life on Earth and I don't think electrolysis of our water would go well on the kind of scale they predict or want in terms of profit motive. Only the future will tell.

Replace the wind turbine with solar panels in places like Spain or Arizona
