You are right, in the longer term, but hydrogen from electrolysis comes at a levelised cost approximately four times grey hydrogen. Of course that is comparing apples and oranges a bit (the grey hydrogen externalises some of its costs) but I think it is still over double as expensive as blue hydrogen. I would be delighted if electrolysis becomes two to four times cheaper than it is today but for a relatively mature chemical process I'm just not sure I see it happening in the next couple of decades.

Or else make the natural gas based fertilizer 4x more expensive through taxes...
