Columbia researchers explore new process to create greener fuels: "While a typical gasification process uses only steam to convert biomass into syngas, synthetic gas containing a mixture carbon monoxide and hydrogen, Castaldi’s new method replaces 30 percent of the water with carbon dioxide. Researchers believe that these findings carry exciting potential and hope the process will be able to improve the overall efficiency of fuel production when used on a large scale. Syngas can be converted into a variety of different chemicals and fuels, including diesel products."

I agree with the linked article that we chould make more use of combined heat and power (chp) production and natural gas, but I do not agree with pitting these technologies against ethanol. CHP can be combined with ethanol production for greater production efficiency. On the use side, most people are going to want liquid fueled engines in combination with plug-in electric in order to extend the range. Ethanol or other high octane biofuels could be the perfect fuel for this application. A small engine running at a consant speed just for battery recharging can be optimized to make the best possible use of ethanol, thereby increasing efficiency of the system. There would be little or no fuel economy deficit when using ethanol in an optimized engine.
ARS researchers have been thinking outside the box. Rather than focusing only on the difficult task of converting xylose into ethanol, they developed yeasts that can use xylose for energy and thereby convert more of the glucose in the feedstock into ethanol. Xylose is a type of sugar that is found in cellulosic biomass. But many cellulosic type materials also contain glucose. Jerusalem artichoke stems and sweet sorghum stems might be good candidates.
New Yeasts Could Help Fast-Track Biofuel Production / July 28, 2009 / News from the USDA Agricultural Research Service: "The new yeast doesn’t directly convert large quantities of xylose into ethanol. Instead, xylose provides energy the yeast needs to grow and reproduce without oxygen. This means that the glucose that might have been used by the yeast to grow and reproduce is now available for fermentation, and the rate of ethanol conversion increases."

This article does a good job of explaining how an engine can be designed to take advantage of ethanol's properties to wipe out the usual fuel economy penalty. This kind of technology could be revolutionary.
AutoSpeed - Going Direct Injected Turbo Ethanol!: "When operated on ethanol blends such as E85, current flex-fuel engines pay a fuel economy penalty of about 30 per cent compared to gasoline. The EBDI engine substantially improves ethanol's efficiency, and performs at a level comparable to a diesel engine."

Also, I doubt the study considered direct injection of high octane biofuels. In this way, a small amount of ethanol or biobutanol can be leveraged to increase fuel economy tremendously. It only requires a small second fuel tank that would be filled infrequently. I suspect it would rival the efficiency of biomass electricity. It would be interesting to see that comparison.
