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. Earlier post.). —Nduagu & Gates.

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. The tar sands are estimated (e.g.,

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

Green Car Congress

In a paper published in the ACS journal Environmental Science & Technology , Stanford University assistant professor Adam Brandt reviews a number of recent life cycle assessment (LCA) studies calculating greenhouse gas (GHG) emissions from oil sands extraction, upgrading, and refining pathways—the results of which vary considerably.

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.”.

Argonne study finds shale gas GHG lifecycle emissions 6% lower than natural gas, 23% lower than gasoline and 33% lower than coal; upstream methane leakage a key contributor

Green Car Congress

Gasoline section shows results for fuel derived from both conventional oil and oil sands. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty whether shale gas emissions are actually lower than those of conventional natural gas.
