NC State Researchers Developing Ozonolysis Pretreatment for Energy Grass Feedstocks

Green Car Congress

Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components. 2008.09.012.

National Academies release third review of the 21st Century Truck Partnership

Green Car Congress

While early R&D was largely component-based, as a result of US Department of Energy (DOE) American Recovery and Reinvestment Act (ARRA) funds in 2009, 21CTP was able to fund four SuperTruck projects. These projects have brought together a wide variety of companies, the national laboratories, and universities. The 50% BTE and the 4.85

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

In general, biofuels made from organic waste are environmentally more benign than those from energy crops. A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials. However very few studies include water use impacts.

Researchers Engineer Yeast to Produce Methyl Halides from Biomass; Precursors for Biohydrocarbon Fuels

Green Car Congress

Researchers at the University of California San Francisco have engineered the industrial yeast S. cerevisiae for metabolism of toxic waste products. Voigt (2009) J. fermentans ferments cellulosic feedstocks to acetate and ethanol, which the modified S. cerevisiae uses to produce methyl halides. Adapted from Bayer et al.
