I don't see how swapping in a spare/emergency battery (be it a Li-Ion today or maybe one of these capacitors in the future) would be any less straightforward than pouring gas in. Especially if these things discharge at such an infinitesimal rate, you could keep a small one in the trunk/boot for whenever it's needed. Or, get a ride to the station and pick one up.

It's all just stored energy, right?


Like Bruno says, it's the size, you're not likely to be able to carry around enough spare batteries or hydrogen to compete with the range you currently get with a petrol canister.
