Hydrogen vs. Battery Electric Cars

At 11:40 the most important point in this discussion is brought up:  Batteries and hydrogen can both be used to absorb excess energy from renewable sources.  The difference is that hydrogen is basically a limitless resource, while the components used in current battery technologies impose a hard limit on how far that solution can go, in terms of all the different transportation requirements a modern society has.  Unless there is some dramatic breakthrough in battery technology, the essentially infinite scalability of hydrogen fuel cells will result in batteries (once again!) losing out in the race to move humanity.
