We were just ramping up research on wood torrefaction processes, then research dollars all but disappeared about 2 years ago. I'll be retired by the time the next research cycle escalates.
Some countries (Brazil, Europe) have working biofuel systems in place. In my opinion, cellulosic biofuel will never work in north America until fuel prices are consistently very high. The logistics and economics of cellulosic biofuel simply don't work at this time.
From this switch grass article:

"the ethanol plant will use 95 semi loads of feedstock per day, requiring a semi to be unloaded every 15 minutes 24 hours per day, 7 days per week....There must be an available land base in the local agricultural landscape to produce feedstock......grown within a 25-mile radius of the bio-refinery, "
This is right by where I live.

DuPont bought out another company and then shut this plant down.
It was using corn stalks and rubish to produce ethanol.
Now a German company is buying it and pkans to produce natural gas.
Considering how cheap natural gas is, I don't know what they are thinking?
Suppose natural gas isn't that cheap by the time it get here through the pipelines?
