U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. Earlier post.).

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

Green Car Congress

In a paper published in the ACS journal Environmental Science & Technology , Stanford University assistant professor Adam Brandt reviews a number of recent life cycle assessment (LCA) studies calculating greenhouse gas (GHG) emissions from oil sands extraction, upgrading, and refining pathways—the results of which vary considerably.

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.”.

Univ. of Alberta and Helmholtz Association Partner to Develop Oil Sands Technologies to Address Environmental Issues

Green Car Congress

The University of Alberta and the Helmholtz Association of German Research Centres signed a memorandum of understanding that will create a five-year agreement, the Helmholtz Alberta Initiative (HAI). The goal of the initiative is to transform oil sands production processes by developing technologies that address sustainability challenges.

ES&T editorial calls Keystone XL a “pipeline to nowhere”

Green Car Congress

Jerald Schnoor, also a professor in the departments of civil & environmental engineering and occupational & environmental health at the University of Iowa, has written an editorial for the journal in which he calls the Keystone XL pipeline a “ pipeline to nowhere ”. Use of coal, oil, and natural gas has to stop (in that order).

Study finds heavy-petroleum fuels raising vanadium emissions; human emissions outpacing natural sources by factor of 1.7

Green Car Congress

and are destined to rise significantly with the use of heavy oils, tar sands, and bitumen as combustion sources. Vanadium is a trace metal found in many earth materials, including petroleum and coal. Human emissions of vanadium to atmosphere now exceed natural sources by a factor of 1.7 —lead author William H.

Researchers Say Mix of Policies and Current or Near-Term Technologies Could Phase Out US CO2 Emissions from Coal-Fired Power Plants by 2030

Green Car Congress

CO 2 emissions from US coal-fired power plant could be phased out entirely by 2030 using existing technologies or ones that could be commercially competitive with coal within about a decade, according to a paper published online 30 April in the ACS journal Environmental Science & Technology.
