Umm... batteries are also like... batteries... how surprising... and like hydrogen are chemical forms of energy storage.

As for how long, probably about 6-24 months... it's actually more a question of capital... if you have the capital i can't imagine it's that difficult to scale up the building of hydrogen storage tanks.

Yes, charging faster is important to people... aren't we having a whole net neutrality debate because being able to download a 2 hr movie in 2 hrs and 30 minutes is no where near as good as being able to download a 2 hr movie in 1h 50m.

I'm pretty sure if you could fly some hydrogen from Berlin to New York in the 20s we can figure out how to make bags for hydrogen. (Yes, some may leak... but who cares, it's not like it doesn't just float away when it gets to the top of the atmosphere...?)
