Why batteries? Why not Bloom Boxes or other H2 fuel cells?
Bloom boxes are scalable fuel cells, which run on natural gas, for which the current distriburion systems are expanding. LNG has a technical advantage over hydrogen as far as containment is concerned (it doesn't leak between the atoms of otherwise solid fuel tank walls). It also is piped all over the country. If car manufacturers insist on sticking with batteries, which are not terribly efficient at storing energy, they will have to switch to a new business model where the car owner doesn't own (or pay for) the batteries. It might also be useful to switch to the Israeli system, where a used battery (charge exhausted) is swapped for a fresh battery is 30 seconds), rather than the current model of owners charging them, which will create a whole new headache for our power grids.
