The cheapest way to produce hydrogen today does indeed involve methane as the starting material, but the promise of hydrogen was that there is a clear path to producing hydrogen from renewables. We can easily do it today, it’s just currently more expensive. If you think of hydrogen like just the energy storage / transport mechanism this isn’t any different than electric infrastructure, where electricity can be produced by fossil fuels or greener alternatives. Lots of people get upset at hydrogen for this reason, but I really don’t think it is warranted. The real reasons to be upset with hydrogen are the various impracticalities with the infrastructure and storage. Hydrogen leaks out of solid metal tanks because the atom is so small, and it has to be kept under enormous pressure because it doesn’t liquefy without cryogenic temperatures. There is no reason that I know of to assume these practicality concerns will ever be solved for car sized applications.
