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.

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.

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

Two new lifecycle studies have found that direct greenhouse emissions from producing, transporting and refining oil-sands derived crude, while greater on average than those from conventional crudes, can also overlap the conventional crude range, depending upon a number of factors.

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.

Ensyn receives EPA regulatory approval for its cellulosic renewable diesel RFDiesel

Green Car Congress

The US Environmental Protection Agency (EPA) recently granted Ensyn Corporation ( earlier post ) Part 79 registration for its renewable diesel product, RFDiesel. FCC units are found in most refineries worldwide and are used to produce gasoline and diesel from vacuum gas oil (VGO). The RTP process is actually an analog to FCC.
