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

Mha (20%) of the peatlands of Peninsular Malaysia, Sumatra and Borneo in 2010, surpassing the area of Belgium and causing an annual carbon emission from peat decomposition of 230–310 Mt CO 2 e. Slightly more than half of the GHG emissions for these biofuels in the EPA’s analysis came from land use change. Earlier post.). —Dr.

Study concludes permanent loss of peatlands in open-pit oil sands mining adds significantly to carbon burden of oil sands production

Green Car Congress

Researchers at the University of Alberta (Canada) have quantified the transformation of the boreal landscape by open-pit oil sands mining in Alberta, Canada to evaluate its effect on carbon storage and sequestration. t of CO 2 lost, as much as 7-y worth of mining and upgrading emissions at 2010 production levels. —Rooney et al.

Catalytic cracking of vegetable oil sludge to produce biohydrocarbons

Green Car Congress

Researchers in Viet Nam and Belgium have developed a catalytic cracking process to convert vegetable oil sludge to renewable hydrocarbon fractions. Vegetable oil sludge is a major byproduct of vegetable oil factories, and consists of triglycerides (61%), free fatty acid (37%) and impurities (2%). 2010.10.060.

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. This is not the same as crude oil occurring naturally in shales, as in the Bakken.

New Review Concludes Very Low EROI of Oil Shale Combined with High Carbon Intensity Likely Makes it an Unsuitable Alternative to Conventional Crude Oil

Green Car Congress

A comparison of estimates of the energy return on investment (EROI) at the wellhead for conventional crude oil, or for crude product prior to refining for oil shale. Oil shale” is shale containing kerogen, a combination of chemical compounds that can be converted into synthetic petroleum. Source: Cleveland and O’Connor.
