Study concludes permanent loss of peatlands in open-pit oil sands mining adds significantly to carbon burden of oil sands production

Green Car Congress

Researchers at the University of Alberta (Canada) have quantified the transformation of the boreal landscape by open-pit oil sands mining in Alberta, Canada to evaluate its effect on carbon storage and sequestration. million metric tons of stored carbon. point out in their paper. —Rooney et al.

Oil sands GHG lifecycle study using operating data finds lower emitting oil sands cases outperform higher emitting conventional crude cases; a call for more sophisticated tools and reporting

Green Car Congress

Well-to-wheel (WTW) greenhouse gas emissions for in situ SAGD and surface mining pathways generated employing GHOST/TIAX/ GHGenius combination and comparison with SAGD, mining and conventional crude oil literature pathways (all results are on a HHV basis). 74% of WTW emissions in our oil sands pathways.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

When peat swamps are drained for agriculture, the peat begins to decompose, and is an enormous source of carbon emissions. Based on visual interpretation of high-resolution (30 m) satellite images, a new study in the journal Global Change Biology: Bioenergy determined that industrial plantations covered over 3.1 —Miettinen et al.

Studies find oil sands-derived crude oil no more corrosive in pipelines than other crudes

Green Car Congress

Both scientific research and industrial experience have found that bitumen-derived crude oil (i.e., crude from the oil sands) is no more corrosive in transmission pipelines than other crudes, according to Natural Resources Canada (NRC). In the absence of water, the crude oil is noncorrosive. —ASTM G205.

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.

New lifecycle analysis of WTW GHG emissions of diesel and gasoline refined in US from Canadian oil sands crude

Green Car Congress

In a new, comprehensive study, a team from Argonne National Laboratory, Stanford University and UC Davis ITS has estimated the well-to-wheels (WTW) GHG emissions of US production of gasoline and diesel sourced from Canadian oil sands. The study is published in the ACS journal Environmental Science & Technology.

Two Lifecycle Studies Find Greater Range in GHG Emissions from both Conventional and Oil Sands Derived Crude Than Previously Shown; Oils Sands Emissions Comparable to Conventional Oil Production in Some Cases

Green Car Congress

A plot from the TIAX study of the ranges of well-to-wheel emissions for different types of crudes in different refinery areas in the US for gasoline production. The two studies represent the first detailed and more granular comparison of domestic, imported and oil sands crude processes in US refineries.
