NREL develops novel method to produce renewable acrylonitrile; carbon fibers from renewable biomass

Green Car Congress

Most importantly for this project, acrylonitrile is also the primary building block in carbon fiber composites, which are used for lightweighting applications in automotive and air transportation. —NREL Associate Laboratory Director Adam Bratis and principal investigator of the NREL-led Renewable Carbon Fiber Consortium.

Converting Oil Shale to Gasoline via Alberta Taciuk Processor Results in Full Fuel Cycle GHG Emissions 1.5-1.75 Larger Than From Conventionally Produced Gasoline

Green Car Congress

Converting oil shale to gasoline via the Alberta Taciuk Processor (ATP)—an above-ground shale retort—results in fuel-cycle greenhouse gas emissions of ~130-150 g CO 2 equivalent/MJ of gasoline produced, according to a new analysis by Dr. Adam Brandt at Stanford University. Emissions from carbonate decomposition are important in both cases.

Researchers modify camelina to produce highest levels yet in transgenic plant oil of novel lipid acetyl-TAG; biofuel and industrial use

Green Car Congress

3-acetyl-1,2-diacyl-sn-glycerols (acetyl-TAG) possess a particularly striking variation where the long-chain fatty acid at the sn-3 position of TAG is replaced by a two-carbon acetyl group. Comparison of typical plant triacylglycerol structure with acetyl-triacylglycerol. —Liu et al.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

The researchers determined the global warming potential, expressed in carbon dioxide equivalents (t e CO 2 ), for seven components of urban inventories: electricity, heating and industrial fuels, industrial processes, ground transportation, aviation, marine, and waste. Authors of the study included: Christopher Kennedy, University of Toronto.

Study casting doubt on GHG benefits of corn stover ethanol draws sharp criticism by other researchers; Liska responds

Green Car Congress

The study led by University of Nebraska-Lincoln assistant professor Adam Liska, funded through a three-year, $500,000-grant from the US Department of Energy, used carbon dioxide measurements taken from 2001 to 2010 to validate a soil carbon model that was built using data from 36 field studies across North America.

US DOE Awards Second Phase of North Dakota Oil Production Study; Targeting Improved Recovery

Green Car Congress

The US Department of Energy (DOE) has awarded an agreement to the University of North Dakota Energy and Environmental Research Center (UNDEERC) to extend a study that will enhance the understanding of factors affecting oil production from the Bakken and Three Forks-Sanish formations within the Williston Basin.
