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. Nominal value of 70 g CO 2 /MJ for combustion emissions is applied evenly across all studies. He found that the variation in oil sands GHG estimates is due to a variety of causes. Credit: ACS, Brandt 2012. Click to enlarge.

Gasoline section shows results for fuel derived from both conventional oil and oil sands. The development of this resource has generated interest in expanding NG usage in areas such as electricity generation and transportation. Expansion bars show the components of fuel production.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states).

Comparison of GHGenius, JACOBS, TIAX, and the new PRELIM gasoline greenhouse gas (GHG) estimates using base case estimates and variations from the scenario analysis. Annual GHG emissions from a large refinery are comparable to the emissions of a typical 500 MW coal-fired power plant. Credit: ACS, Abella and Bergerson. Click to enlarge.

ExxonMobil Outlook: 35% growth in energy demand by 2040; hybrids to account for ~50% of new vehicle sales

Green Car Congress

Demand for energy in non-OECD nations will grow by about two-thirds, accounting for essentially all of the increase in global energy use. The growth reflects an expected 90% increase in electricity use, led by developing countries where 1.3 billion people are currently without access to electricity. Transportation.

PHEV's and Water Consumption

Plug In Partners

Water Supply, Researcher Says By Jennifer Bogo Popular Mechanics March 7, 2008 "A 30-mile commute in a gasoline-powered car would require the withdrawal of 18.9 The same commute in a plug-in hybrid electric vehicle (PHEV), meanwhile, would take a whopping 318 gallons. And what about the water used to refine gasoline?
