Hah! It's amazing how many people are still hanging onto the delusion that hydrogen is made from renewables when almost every ounce of commercial hydrogen fuel is made by cracking petroleum products.
What you're saying is true. I still want to point out that developing hydrogen infrastructure based on non-renewable hydrogen today, helps lay the groundwork for using primarily renewable hydrogen tomorrow, because we're developing storage, transportation, and fuel cell technology.
Also: Methane can be produced from renewables, so developing steam reforming technology today, using non-renewable methane, helps lay the groundwork for renewable-based hydrogen production tomorrow.
Finally: Steam reforming lends itself well to CCS, so hydrogen production from renewable methane + CCS is a potentially viable path to a carbon-negative future.
But hydrogen infrastructure isn't better long term than regular electric and battery infrastructure. You need quite unique circumstances like being highly dependent on high energy density while being located in a place where you're far from an electric grid. Like an island in a stormy place (without access to wave power, etc) or long haul trucks out in nowhere or electric airplanes. Almost anything else should use better options
This is the dream we follow while driving our gasoline cars.
