Cellulosic technologies are biofuel conversion technologies that can convert cellulosic biomass into liquids. This category includes both biochemical and thermochemical conversion.
- Cellulosic biomass consists of plant matter composed of linked glucose molecules that strengthen the cell walls of most plants. Cellulosic ethanol is usually produced from cellulosic biomass by using acid-based catalysis or enzyme-based reactions to break down plant fibers into sugar, which is then fermented into ethanol.
- According to the Environmental and Energy and Study Institute (EESI), "Cellulose is the most abundant naturally-occurring organic compound on earth and its efficient conversion to renewable energy would represent an important breakthrough."[1]

News
- New, "better" biofuels are no magic bullet, 4 June 2008 by Reuters: "commercial production of [second generation] biofuels, for instance using woody cellulose, grasses or algae, is years away" and such biofuels "'are not expected to be produced on a commercial basis' in the next decade, according to a report by the U.N.'s Food and Agriculture Organization and the Organisation for Economic Cooperation and Development."
- Australian researchers develop process to produce stable bio-crude oil, 4 February 2008, from Biopact. Researchers in Australia have found a process that will turn lignocellulosic biomass into bio-oil. The stability of the new bio-oil is an important development.
- Genencor launches first ever commercial enzyme for cellulose ethanol. "Genencor, a division of Danish company Danisco A/S, announced the launch of Accellerase 1000, the first ever commercially available biomass enzyme developed specifically for second generation biorefineries. "
