Why not? Methanol fuel cell plug-in hybrids

Better than hydrogen?

Fuel cell stacks are shrinking. Lithium-ion batteries are getting lighter and more powerful. This combination alone means the need for hydrogen to power fuel cell vehicles is shrinking. Of course, where are the hydrogen pumps?

Already, automakers, such as Ford, are exploring hydrogen infrastructure gaps with plug-in hybrid functionality by developing plug-in fuel cell hybrid prototypes. This enables such a vehicle to use both hydrogen and electricity for power. Yet, what if hydrogen could be replaced with a fuel like methanol that not only can utilize a fuel cell, but also work within the current refueling infrastructure of America?

While many, including this writer, have consistently questioned biofuels, particularly ethanol, methanol seems to have some distinct advantages over other biofuels. Off the bat a fuel cell could double the efficiency of methanol. Add hybrid technology and another 30 percent in efficiency is achieved. Add plug-in functionality and little methanol would ever be needed, except for long trips, day-time refueling or other periods of high electricity costs.

Automakers are going to pursue biofuels, fuel cells, hybrid vehicles and EVs regardless of whom becomes the next President. Shouldn't the synergies of these technologies also be pursued?

I think this (ethanol/electric) hybrid is a great alternative. The only situation where I would be against it (and against any use of biofuels) is if crops are used to create the biofuel. In my opinion, there is something terribly wrong (and very inefficient) with growing crops for the purpose of creating fuel - especially when a great majority of the population is underfed, and when food cost are rising. Loosing crops to fuel would only make food costs rise.

But thats just me!

i agree, Jocelyn. in fact, if automakers are going to receive flex fuel credits for ethanol, I think those vehicles should, minimally, also be mild hybrids, although i would prefer they be full hybrids.
