A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands 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.

An analysis of the US refining sector, based on linear programming (LP) modeling, finds that refining plausibly high volumes of Canadian oil sands 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.

Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oil sands 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 oil sands. Click to enlarge.

From a cost perspective, the potential of alternative fuels is of limited, if any value, according to the lead report written by James Bartis, a RAND senior policy researcher. While DoD and the services will have access to the wholesale fuel supplies they require, the purchase price may be uncomfortably high. Earlier post.).

Normalized well-to-wake GHG emissions for low-, baseline- and high-emission cases for jet fuel pathways under different land use change scenarios. The focus of the work was on alternative jet fuels that could be available commercially in the next decade using primarily North American resources. From Hileman et al.

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. —Brandt et al.
