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.). —Nduagu & Gates.

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.

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

Green Car Congress

The goal of the initiative is to transform oil sands production processes by developing technologies that address sustainability challenges. The University of Alberta, recognized as a global leader in oil sands research, will work with the Helmholtz Association, a collection of 16 science and technology centers across Germany.

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. Excessive V in air and water has potential, but poorly documented, consequences for human health. Schlesinger, James B.

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. The novel system shows potential for tackling global problems in a patient, thoughtful, and human-scaled way. There is nothing special here!”
