What is the energy cost to synthesize butanol from biomass? It's bound to be costlier than ethanol, which is already too costly. It's all fine and good to make a fuel that's more convenient to use, but if a good deal of the feedstock gets used up in its production, the overall cost will be problematic, as will the availability of biomass itself.

More than twice as much fuel (energetically) can be obtained from biomass in the form of methane compared with can be obtained as ethanol. (Yes, this includes cellulosic ethanol.) Butanol is going to be much worse.

At best, our domestic biomass can only provide about 10% of our energy needs anyway, so we shouldn't be wasting what we do have synthesizing a complex fuel that will be even more expensive than ethanol!
