Hydrogen production as replacement fuel for some niche markets, for one. But it has other uses: -Greening up steel mills. -Local nitrogen fertilizer production. As in: on-farm (not @ scale atm, but it's been demonstrated). -Overlapping: ammonia production (more centralized in big chemical plants). For fertilizer production as well, but also feedstock in a # of chemical processes (and probably other uses). -H2 itself likely has uses as feedstock in chemical processes. These are mostly large-scale uses, so just moving the needle involves a big investment in electrolyzers.
