Dave, yes I'm told too (by a friend who's a CEO of a corn ethanol company)
that biobutanol will be handled exactly like gasoline. We were having a
drink the other day as my TR3B was parked on the street in front of us, and
he pointed to my car noting that butanol would be indistinguishable from
gasoline in it.
One of the other developments underway is cellulosic butanol at some point,
too.. DuPont and BP have a venture that is ready to break ground on an
ethanol/biobutanol plant from corn stover.
More from Wikipedia on butanol fuel (
https://en.wikipedia.org/wiki/Butanol_fuel). In theory, about a 10%
consumption hit for butanol.
Gasoline:
Fuel energy density 32 MJ/L
RON 9199
MON 8189
Butanol fuel
Fuel energy density 29 MJ/L
RON 96
MON 78

technology)
