Researchers Suggest That Although CCS and Other Technologies Could Reduce Oil Sands GHG Emissions to Near Zero, That Strategy May Not Make Sense

Green Car Congress

Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., The source material is neither oil nor tar but bitumen, but is most generally described as an example of ultraheavy oil.”.

Transcanada restarts Keystone oil sands pipeline operations

Green Car Congress

TransCanada Corporation said that its 590,000 barrel-per-day (bpd) capacity Keystone Pipeline system resumed transporting oil sands crude on Sunday, 5 June, after a shutdown 29 May following an above-ground spill at a pump station in Kansas involving less than 10 barrels of oil.

Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

Full-fuel-cycle GHG emissions estimates for reformulated gasoline pathways by LCA study. Nominal value of 70 g CO 2 /MJ for combustion emissions is applied evenly across all studies. He found that the variation in oil sands GHG estimates is due to a variety of causes. Credit: ACS, Brandt 2012. Click to enlarge.

EIA projects world energy use to increase 53% by 2035; oil sands/bitumen and biofuels account for 70% of the increase in unconventional liquid fuels

Green Car Congress

The transportation sector accounted for 27% of total world delivered energy consumption in 2008, and transportation energy use increases by 1.4% World oil prices remain high in the IEO2011 Reference case, but oil consumption continues to grow; both conventional and unconventional liquid supplies are used to meet rising demand.

Ecofys report concludes current European regulations underestimating GHG reductions

Green Car Congress

Substituting biofuels for marginal fossil-based liquid fuels results in the avoidance of significant GHG emissions that are not currently accounted for in the European Renewable Energy Directive (2009/28/EC), according to a new analysis by the consultancy Ecofys. Both effects increase the carbon footprint of conventional oil.

New petroleum refining lifecycle model finds the variability in GHG emissions from refining different crudes as significant as magnitude expected in upstream operations

Green Car Congress

PRELIM uses a more comprehensive range of crude oil quality and refinery configurations than used in earlier models and can quantify energy use and greenhouse gas (GHG) emissions with detail and transparency the better to inform policy analysis, the duo suggests.
