Jed,

A plug-in hybrid hydrogen ICE would get fantastic mileage AND range. You could recharge both the batteries and the hydrogen at your house overnight, with a small electrolytic converter. It seems ideal.

Yes! This is definitely the best way to go: the H2 plug-in Hybrid. Even without a storage breakthrough, in such a redesigned hybrid - a small (motorcycle sized) H2 burning ICE would be useful to extend the commuter-range of mileage of the vehicle's batteries - and could then we can use the old-style compressed H2 storage - which is too bulky for use in a non-hybrid situation, with a larger engine.

Let's see... for the plug-in hybrid. Even without a major breakthrough in batteries or H2 storage, one could have a vehicle with total electric motor drivetrain, enough batteries for a 25+ mile commute (say 6- large marine grade lead-acid batteries - 240 pounds). A small 1 liter gen-set for longer highway use or to recharge the batteries in an emergency. The H2 could be carried in a single pressurized cylinder in the safest place in an automobile (under the rear seat) giving a 200 mile range - when needed. In a normal commute, it would be all electric with a nightly recharge.

This would be slightly heavier and bulkier than the current Prius - but has the large advantage of much longer all-electric range - yet the ecological advantage of no local pollution if the H2 must be used. Perfect for the "other" California (LA) and other areas which are smoggy. Since the H2 is not normally used, one would not need to make it at home and could purchase it in converted filling-stations.

I like it.
