I really hope it works out like this. But right now, the technological challenges (electrolysis cells are expensive at GW scale, transporting and storing hydrogen is dangerous and expensive) are substantial. I just don't see a scale where a hydrogen electrolysis facility that only runs on days with excess electricity production is more economically feasible than running a thermal hydrogen reformer of a natural gas pipeline and using the natural gas itself for the applications where you end up just burning it anyway. Gigantic taxes on CO2 emission could fix this, but ever then hydrogen would need a couple of breakthroughs to make it more economical than carbon capture and storage.
