Researcher urges more effort on assessment of land and water impacts of oil sands production; reference point for other unconventional fuels

Green Car Congress

Bitumen production from the Canadian oil sands provides a point of reference that could be used to observe and better manage the land and water impacts of a rapid transition to unconventional fuels, suggests Dr. Sarah Jordaan of the Energy Technology Innovation Policy Research Group, Department of Earth and Planetary Sciences, Harvard University.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Historical analysis shows strong acceleration of plantation development in recent years: 70% of all industrial plantations have been established since 2000 and only 4% of the current plantation area existed in 1990. That number is in my opinion conservative, and consistent with a slight reduction in the rate of peat conversion.

The Reference case in AEO2014 assumes that VMT per licensed driver begins to increase after 2018. In the Low VMT case, total US LDV travel demand in 2040 is 19% lower than in the Reference case with annual increase in total LDV VMT from 2012 through 2040 averaging only 0.2%. —Hutchins and Maples. —below the 1.7%

SwRI D-EGR gasoline demo vehicle delivers diesel efficiency at lower cost; potential for LEV III/Tier 3 emissions

Green Car Congress

In their paper, the SwRI researchers reported that the conversion to D-EGR improved engine efficiency and fuel consumption at least 10% across the performance map, with some operating conditions seeing substantially higher improvements. D-EGR brake specific fuel consumption (BSFC) at 2000 rpm 2 bar BMEP dropped 14.3% Chadwell et al.
