U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

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.

Study finds plausibly high volumes of Canadian oil sands crudes in US refineries in 2025 would lead to modest increases in refinery CO2 emissions

Green Car Congress

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.

RAND reports suggest US DoD use less petroleum fuel to deal with high prices, not count on alternatives

Green Car Congress

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. Pending a major technical breakthrough, renewable jet and marine fuels will continue to be far more expensive than petroleum-based fuels, Bartis said.

Stanford, UC Santa Cruz study explores ramifications of demand-driven peak to conventional oil

Green Car Congress

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).

MIT/RAND Study Concludes Three Types of Alternative Jet Fuel May Be Available in Commercial Quantities Over the Next Decade

Green Car Congress

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.
