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.

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.

Ecofys report concludes current European regulations underestimating GHG reductions

Green Car Congress

The study was commissioned by the European Oilseed Alliance (EOA), the European Biodiesel Board (EBB) and the European Vegetable Oil and Proteinmeal Industry (FEDIOL). In addition, they argue, biofuels should not just be compared to the average performance of gasoline or diesel but with the fossil fuels they most likely replace—i.e.

State Department issues Draft Supplemental Environmental Impact Statement on Keystone XL Pipeline: climate change impacts

Green Car Congress

The US Department of State (DOS) has released its Draft Supplemental Environmental Impact Statement (SEIS) in response to TransCanada’s May 2012 application for the Keystone XL pipeline that would run from Canada’s oils sands in Alberta to Nebraska. The pipeline would primarily transport crude oil from the WCSB and Bakken regions.

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.
