New UC Davis market-based sustainability forecasting approach concludes supplanting gasoline and diesel with renewable fuels could take 131 years

Green Car Congress

At the current pace of research and development, replacing gasoline and diesel with renewable fuel alternatives could take some 131 years, according to a new University of California, Davis, study using a new sustainability forecasting approach based on market expectations. —Nataliya Malyshkina, UC Davis postdoctoral researcher.

CRC study finds some adverse results from use of mid-level ethanol blends in MY 2001-2009 engines; DOE and ethanol industry say study significantly flawed

Green Car Congress

Growth Energy, an ethanol industry trade group, petitioned the EPA in March 2009 to raise the limit on ethanol in gasoline from 10 to 15 percent. The CRC Engine Durability study took duplicates of eight different vehicle model engines spanning 2001-2009 model years. Background.

UC Davis ITS researchers take a detailed look at water consumption and withdrawal requirements for ethanol

Green Car Congress

Water is required for crude oil recovery by water flooding, enhanced oil recovery via steam injection, and steam extraction of bitumen from oil sands and during refining of crude oil to produce gasoline. BW consumption intensities of gasoline from conventional crude oil and Canadian oil sands range from 0.41 and from 0.29

New lifecycle analysis of WTW GHG emissions of diesel and gasoline refined in US from Canadian oil sands crude

Green Car Congress

In a new, comprehensive study, a team from Argonne National Laboratory, Stanford University and UC Davis ITS has estimated the well-to-wheels (WTW) GHG emissions of US production of gasoline and diesel sourced from Canadian oil sands. This finding agrees with previous work. —Cai et al. Hao Cai, Adam R.

Study Concludes Cash for Clunkers Program Is an Expensive Way to Reduce Carbon; Paying Nearly 10x the Projected Price of Carbon Credits

Green Car Congress

program is paying nearly 10 times the projected price of carbon credits per ton in the best-case scenario, according to an analysis of the implied cost of carbon dioxide reductions under the program by UC Davis transportation economist Christopher Knittel. A gallon of gasoline creates roughly 20 pounds of carbon dioxide when combusted.

UC Davis Study Finds That Near-Term Marginal Electricity Mix in California for Plug-in and Fuel Cell Vehicles Will Result in Fuel With Carbon Levels More Than 60% Higher Than Estimated in the LCFS

Green Car Congress

The study also concluded that despite the relatively high fuel carbon intensity of marginal electricity in California, alternative vehicle and fuel platforms still reduce emissions compared to conventional gasoline vehicles and hybrids, through improved vehicle efficiency.
