[semi-extrinsic]

Production from natural gas using steam methane reforming plus water gas shift reaction is how 95% of the worlds hydrogen is made. After these processes, one must anyways separate out the CO2, to make the H2 usable. This is done at industrial scale, hundreds of billions of standard cubic metres every year. Mostly the CO2 is just released, but increasingly it is caputred and stored.

The technology is easily scalable to meet demand, in fact it has to scale far less than how much battery production has to scale from current levels.

I'm convinced it's not a question of if, but a question of when this becomes a major thing. We're at the point where we need all the technological and societal mechanisms we can muster.

Define 'increasingly'

And after you get you H2, what are you going to do with it? You're not going to use it to power vehicles, that's for sure.
