Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

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. These include oil sands, enhanced oil recovery, coal-to-liquids and gas-to-liquids synthetic fuels, and oil shale.

Researchers Suggest That Although CCS and Other Technologies Could Reduce Oil Sands GHG Emissions to Near Zero, That Strategy May Not Make Sense

Green Car Congress

Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., The source material is neither oil nor tar but bitumen, but is most generally described as an example of ultraheavy oil.”.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. Anthropogenic climate change confronts humanity with a challenge: How can we keep warm now as we try to prevent our world from overheating in the future?

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.

Fossil Fuel Production Up in 2008 Despite Recession

Green Car Congress

World production of fossil fuels—oil, coal, and natural gas—increased 2.9% million tons of oil equivalent (Mtoe) per day, according to a Worldwatch Institute analysis. Energy prices reflected this shift: oil peaked at $144 per barrel in July, then fell to $34 per barrel in December. Oil production reached 10.7

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.

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

PRELIM uses a more comprehensive range of crude oil quality and refinery configurations than used in earlier models and can quantify energy use and greenhouse gas (GHG) emissions with detail and transparency the better to inform policy analysis, the duo suggests.
