Argonne study finds BEVs can have lowest scheduled maintenance costs, but highest cost of driving

Green Car Congress

Researchers at Argonne National Laboratory, with colleagues from Lawrence Berkeley, Oak Ridge, and National Renewable Energy labs, and the University of Tennessee, have published a comprehensive analysis of the total cost of ownership (TCO) for 12 sizes of vehicles ranging from compact sedans up to Class 8 tractors with sleeper cabs.

Study finds clear trend of increasing NOx with higher biodiesel blends with CARB diesel; NOx neutrality achieved by blending in renewable or GTL diesel

Green Car Congress

NO x emissions results of biodiesel, renewable, and GTL diesel fuel blends, and CARB diesel fuel for 2006 Cummins ISM. They also found that increasing renewable diesel (Neste Oil’s NExBTL) and gas-to-liquids (GTL) diesel blends showed NO x reductions with rising blend level. The GTL diesel fuel showed reductions of 5.2%

million) research project to investigate the use of alternative fuels that could offer customers the power and performance of modern internal combustion engines with environmental benefits comparable to an electric vehicle. It is estimated that DME from renewable energy sources could offer well-to-wheel emissions of about 3 g/km CO 2.

New UMTRI paper reviews major advantages and disadvantages of battery-electric and fuel-cell vehicles

Green Car Congress

A new report from the University of Michigan Transportation Research Institute (UMTRI) reviews the major advantages and disadvantages associated with battery-electric vehicles (BEVs) and fuel-cell vehicles (FCVs). Michael Sivak also incudes information for current gasoline-powered internal combustion engines as a baseline comparison.

DeCicco: Transportation GHG reduction policy should focus upstream on fuel supply rather than downstream on choice of fuels in vehicles

Green Car Congress

John DeCicco at the University of Michigan argues that to reduce transportation sector greenhouse gas emissions, the proper policy focus should be upstream in sectors that provide the fuel, rather than downstream on the choice of fuels in the automobile. In a new working paper, Prof. A parametric analysis by Barter et al.

The Case for Nuclear Cargo Ships

Cars That Think

The IMO’s previous goal was a 50 percent reduction by 2050 in comparison with 2008 levels. At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore.
