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

Full-fuel-cycle GHG emissions estimates for reformulated gasoline pathways by LCA study. He found that the variation in oil sands GHG estimates is due to a variety of causes. These include oil sands, enhanced oil recovery, coal-to-liquids and gas-to-liquids synthetic fuels, and oil shale.

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

The majority (62%) of the plantations were located on the island of Sumatra, and more than two-thirds (69%) of all industrial plantations were developed for oil palm cultivation, with the remainder mostly being Acacia plantations for paper pulp production. Earlier post.).

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. Click to enlarge.

Ensyn granted EPA Part 79 approval for renewable gasoline

Green Car Congress

Ensyn ( earlier post ) has been granted a key regulatory approval from the US Environmental Protection Agency (EPA) for its renewable gasoline product, RFGasoline. The RTP pyrolysis process is based on the application of a hot “transported” bed (typically sand) that is circulating between two key vessels. Earlier post.).

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.

State Department releases final environmental impact statement on Keystone XL Pipeline Project; analysis of GHG emissions

Green Car Congress

Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oil sands using different production processes relative to gasoline produced from reference crudes. The proposed Project is not likely to impact the amount of crude oil produced from the oil sands.
