The WTO is structured to resist any initiative to reduce the power of the businesses that it exists to serve. Of course, it claims that this is for our own good, to ensure plenty of wealth for the rich that could theoretically trickle down to the rest of us.

It is physically possible to make hydrogen and use it as a fuel, and it's renewable if generated using renewable electricity, but that is inefficient use of funds. In this decade we can decarbonize more by converting the uses of energy to run off renewable electricity.
