Biobutanol fuel of choice in US transcontinental flight project

Biobutanol is going to be the fuel of choice in a flght across the US. You can follow the flights as they hop across the continent here. The route will take the “LookLocal Get The Lead Out” campaign  from the Pacific
Ocean to the First Flight Airport in Kitty Hawk, North Carolina.

    I did not dig deep, but there is no info about how this biobutanol would be produced. It seems that the benefits of using biobutanol would be higher volumetric energy density compared to ethanol and the capability to blend higher %s of biobutanol with gasoline. More info from wikipedia .

    Biobutanol is also more chemically like gasoline than ethanol, it can be added to ethanol gasoline mixtures to get water, which can be absorbed by ethanol, out of the mixture. It looks like the kind of thing that you’d invent from a blank sheet of paper. But we’ve got a lot of volume devoted to ethanol. I wonder how easy it would be to convert ethanol fermentation to butanol fermentation…

    From what I have read, switching from ethanol to bio-butanol production should be pretty easy. Change the yeast or bacteria and the catalysts and you are in the bio-butanol business.

    The bigger problem so far is yield, bio-butanol yields are too low to compete. I would expect someone to break thru that barrier before long.

    I give it a strong likelihood of long term success, and of replacing Ethanol some day. The switch over should be painless.
