Assessing the Economic Potential of Advanced Biofuels

Dean Dibble prepares samples of switchgrass for analysis. (Photo by Randy Wong) Biofuels hold great promise for the future of transportation energy, but how near we are to that future is, at best, an educated guess with many variables at play. A study led by Scott Paap (Systems Research and Analysis Dept.), “Biochemical production [...]

JBEI Researchers Splice Corn Gene into Switchgrass, Increasing Plant Cell Wall Starch by 250%

Many experts believe that advanced biofuels made from cellulosic biomass are the most promising alternative to petroleum-based liquid fuels for a renewable, clean, green, domestic source of transportation energy. Nature, however, does not make it easy. Unlike the starch sugars in grains, the complex polysaccharides in the cellulose of plant cell walls are [...]

E. Coli Bacteria Engineered to Eat Switchgrass and Make Transportation Fuels

A milestone has been reached on the road to developing advanced biofuels that can replace gasoline, diesel, and jet fuels with a domestically produced clean, green, renewable alternative. Researchers with the U.S. Department of Energy's Joint BioEnergy Institute (JBEI) have engineered the first strains of Escherichia coli bacteria that can digest switchgrass biomass [...]

Thermochemical Conversion

Thermochemical conversion of biomass to fuels has become increasingly important as climate and energy security issues challenge our dependence on conventional energy sources. Sandia provides the enabling science and engineering basis for the next generation of thermochemical platform technologies for biomass to fungible fuels and power.  Thermochemical fuels research expertise includes biomass pre-treatment, fast-pyrolysis, char [...]

Microalgae

Advanced biofuels derived from microalgae at the commercial scale could meet, depending on productivity, the transportation fuel needs of the entire United States using a relatively small land area as compared to that required by lignocellulosic fuels. Microalgae consume CO2 as a nutrient, can be grown with impaired (e.g., brackish) water sources on land that does [...]

Lignocellulosic Biomass

Lignocellulosic biomass is one of the most abundant plants on Earth and is a critical feedstock for the production of renewable fuels. Lignocellulose is a mixture of complex sugars and lignin, a non-carbohydrate polymer that provides strength and structure to plant cell walls. By extracting simple fermentable sugars from lignocellulose and producing biofuels, the [...]

Energy Conversion Efficiency

Sandia National Laboratories has advanced research in solar, wind, and geothermal energy science and technologies since the 1970s. More recently, climate-change concerns, coupled with high oil prices and increasing government support, are driving increasing renewable-energy legislation, incentives, and the commercialization of renewable technologies. In response, Sandia has added research programs in biofuels and biomass [...]

Co-Evolution of Biofuels

This program includes the development of thermochemical and biochemical conversion technologies routes to efficiently generate renewable biofuels from two primary feedstock types – lignocellulose and microalgae. Both of these feedstocks have significant promise in terms of displacing fossil fuels, but significant challenges remain that require further research and development. Co-evolution of Biofuels and Engines [...]
