From really long term hydrogen makes a lots of sense, much more than Li-* batteries. There is no need for digging up rare earth metals, H2 is a byproduct of creating graphene and various processes can create it. Also filling up liquid hydrogen takes still less, than any charging available. And IMO it can be much cleaner than any other technology on horizon currently. Only more effective but not necessarily cleaner are the plans for small nuclear power plants.
