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.

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.,

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.”.

ES&T editorial calls Keystone XL a “pipeline to nowhere”

Green Car Congress

Use of coal, oil, and natural gas has to stop (in that order). But “dirty” oil, emanating from oil sands (a.k.a., tar sands) with a significantly higher carbon footprint than conventional oil, deserves a place at the front of the line. Keystone XL would add to global greenhouse gas emissions.

IEA: global map of oil refining and trade to be redrawn over next 5 years

Green Car Congress

Profound shifts in the regional distribution of oil demand and supply growth will redefine the refining industry and transform global oil trade over the next five years, according to the annual Medium-Term Oil Market Report (MTOMR) released by the International Energy Agency (IEA). The oil market is at a crossroads.
