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. g CO 2 e/MJ for US conventional crude oil recovery. M+B = surface mined bitumen.

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

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.

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.

New petroleum refining lifecycle model finds the variability in GHG emissions from refining different crudes as significant as magnitude expected in upstream operations

Green Car Congress

Comparison of GHGenius, JACOBS, TIAX, and the new PRELIM gasoline greenhouse gas (GHG) estimates using base case estimates and variations from the scenario analysis. The configurations are differentiated by the presence of gas oil hydrocracking; fluid catalytic cracking (FCC); delayed coking; and residual hydrocracking.

Coskata Unveils Semi-Commercial Feedstock-Flexible Ethanol Facility; Springboard for Full-Scale Commercial Rollout

Green Car Congress

The Coskata process can produce more than 100 gallons of ethanol per ton of dry, ash-free biomass material at a cost competitive with expected gasoline prices—around $1.00 By comparison, the theoretical yield of ethanol from a dry ton of corn is 124.4 We will produce ethanol directly cost-competitive with gasoline.” —Wes
