There's one case, rural areas often have abundant energy sources (hydro, wind,etc) but few consumers, in Northern Sweden f.ex. a lot is produced but there's a lot of losses in transporting the energy south.

Now, yes, as long as natural gas is cheap(inbetween US or Soviet wars) it'll probably be the core for hydrogen, however batteries won't help much in the north since the transmission rather than usage is the cap even with batteries so excess production could be redirected towards hydrogen production.
