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.).

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

Based on visual interpretation of high-resolution (30 m) satellite images, a new study in the journal Global Change Biology: Bioenergy determined that industrial plantations covered over 3.1 Slightly more than half of the GHG emissions for these biofuels in the EPA’s analysis came from land use change. Earlier post.).

Study finds that native microbes biodegrade longer-chain hydrocarbons in oil sands tailings to methane; implications for management of tailings and GHG emissions from tailings ponds

Green Car Congress

Proposed anaerobic hydrocarbon biodegradation pathways in oil sands tailings. The researchers now report that higher molecular weight n -alkanes (C 14 , C 16 , and C 18 ) are also degraded under methanogenic conditions in oil sands tailings, albeit after a lengthy lag (180 days) before the onset of methanogenesis.

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

As we try to objectively study nature, we are often reminded of how natural forces affect us personally. 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. There is nothing special here!”

Stanford, UC Santa Cruz study explores ramifications of demand-driven peak to conventional oil

Green Car Congress

In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).
