The industry is starting to say that hydrogen is not going to happen. It's expensive to make even with hydrolysis, explosive, and extremely leaky. That makes transportation and storage really difficult. Also, I think it contributes to warming when enough leaks.

Hydrogen as fuel won't work, yes; but generating it and immediately making hydrocarbons or ammonia or other chemical feedstocks with it is perfectly feasible. It's already being done. Just not with electrolysis.
