Nexant, Inc. has published a study (based on technoeconomic modeling), which looks into the “current, emerging, and future technologies” in biofuels. Some of its findings and conclusions are: (1) biodiesel (as fatty acid methyl ester) is seen as a “transition technology”, which would substitute only a small fraction of the global demand for diesel, (2) the next phase in bioethanol development would be ethanol fermentation of substrates obtained from hydrolysis of biomass feedstocks, (3) biofuels production from themochemical processing will be a major technology player for producing “gasoline and diesel range biofuels”..
