An analysis of the US refining sector, based on linear programming (LP) modeling, finds that refining plausibly high volumes of Canadian oilsands crudes in US refineries in 2025 would lead to a modest increase in refinery CO 2 emissions (ranging between 5.4% to 9.3%) from a 2010 baseline, depending upon the supply scenario.
A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oilsands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.
Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oilsands using different production processes relative to gasoline produced from reference crudes. The proposed Project is not likely to impact the amount of crude oil produced from the oilsands. Click to enlarge.
The five different fuel groups were those derived: from conventional petroleum; from unconventional petroleum; synthetically from natural gas, coal, or combinations of coal and biomass via the FT process; renewable oils; and alcohols. Certain HRJ and FT fuels are able to reduce the GHG emissions from aviation. million bpd.
The wireline logs, fluid samples and pressure data confirmed the presence of gas and condensate in 38m (125 feet) net of Oligocene sands in Salamat. The well was drilled using the sixth-generation semi-submersible rig Maersk Discoverer in water depth of 649 meters (2,129 feet) and reaching a total depth of around 7,000 meters (22,966 feet).
The California LCFS calls for at least a 10% reduction from 2006 levels in the carbon intensity (measured in gCO 2 e/MJ) of California’s transportation fuels by 2020. By regulating the fuel pathway of transportation fuels—i.e., This is a critical tool to help us break our dependence on fossil fuels.
Building on LCFS policies already adopted in Europe, British Columbia, and California, the researchers looked at potential costs and benefits of reducing the carbon intensity of transportation fuels by 10 to 15 percent by 2030. Create separate fuel pools for gasoline and diesel. We did not shy away from controversy.
In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).
volume and GHG-based fuel standards) to achieve reductions in greenhouse gas emissions from on-road transportation need to evolve towards energy-intensity-based fuel standards (e.g., MJ/km) and complementary regulation of fuel carbon intensity (e.g., Vehicle regulations (e.g., —Creutzig et al.
The architecture is also designed to support hybrid propulsion systems and alternativefuels. The high-pressure casting method produces a more dimensionally accurate block that requires fewer machining operations than conventional sand-cast blocks. A die-cast aluminum oil pan contributes additional structural strength.
However, you should not delay inclusion of known sources of emissions, including indirect emissions from biofuels, pending discovery of potential effects from other fuels. To spur innovation in low carbon fuels, the LCFS must send an accurate signal to the growing clean energy market.
Direct injection and flex fuels require a more robust valvetrain system due to the increased friction, higher thermal loads, increased oxidation and reduced lubrication associated with alternatefuels that do not contain some of the natural lubricants found in gasoline.

Running on 87 octane, the front wheels (all-wheel drive is not available) are driven through a Continuously Variable Transmission (CVT) that has five driver selectable drive modes of Eco, Normal, Sport, Slippery and Snow/Sand. The Environmental Protection Agency, EPA , rates fuel economy at 40 highway when running in gasoline mode only.
To maximize performance and efficiency there are five driver selectable drive modesConserve, Normal, Excite, Slippery and Snow/Sand. The Environmental Protection Agency, EPA , rates fuel economy at 33 highway and combined when running in hybrid mode only. There is a sixth mode of Preserve, which saves the battery charge for later use.
To maximize performance and efficiency there are five driver selectable drive modes of Conserve, Normal, Excite, Slippery and Snow/Sand. The Environmental Protection Agency rates the Corsair’s fuel economy at 33 mpg highway and combined when running in hybrid mode only. The Corsair–hiding in plain sight.
If you consider buying one, make sure you plan on spending time off-pavement seeking sand, mud and snow, as its DNA is far different from any other SUV on the market. Maintenance – Three years for three, no-cost oil changes and tire rotations. This 4×4 is all 4×4, dripping with Jeep’s legendary off-road heritage.
The “wet” part of a DCT means it uses oil to improve lubrication and cooling. A “dry” DCT does not use oil, but is the more fuel efficient of the two types. That is joined by exterior colors of Hampton Gray, Phantom Black, Sage Gray, Ice White and Mojave Sand. A torquey turbo four.
will become less common over the next 10-years and that a mix of alternativefuel vehicles including electric, biofuel, hydrogen and solar will and is now seeing tremendous market growth. You also repeat the "peak oil" argument that Ive been reading since the 60s. We have oil! Think Bakken and Alberta sands.
From a cost perspective, the potential of alternativefuels is of limited, if any value, according to the lead report written by James Bartis, a RAND senior policy researcher. Pending a major technical breakthrough, renewable jet and marine fuels will continue to be far more expensive than petroleum-based fuels, Bartis said.
