Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

Green Car Congress

The study estimated national fuel and emissions impacts from increasing reliance on electrified light-duty transportation, and the resulting implications for advanced biofuels. For comparison, they team estimated the RFS goal for cellulosic fuels to be equivalent to 1289 PJ. —Meier et al. billion gallon) and 4540 PJ (56.4

IEA working paper highlights potential role of natural gas in reducing global road transport CO2

Green Car Congress

On average, a 25% reduction in carbon dioxide equivalent (CO2-eq) emissions can be expected on a well-to-wheel (WTW) basis when replacing gasoline by light-duty vehicles (LDVs) running on compressed natural gas (CNG).

Study suggests current levels of methane leakage would result in numerous decades of more rapid climate change from a shift to natural gas vehicles

Green Car Congress

A) CNG light-duty cars vs. gasoline cars; (B) CNG heavy-duty vehicles vs. diesel vehicles; and (C) combined-cycle natural gas plants vs. supercritical coal plants using low-CH 4 coal. A TWP >1 means that the cumulative radiative forcing from choosing natural gas today is higher than a current fuel option after t yr.

NHTSA Modeling and Technology Projections Underlying the Proposed CAFE Target of 34.1 mpg by MY 2016

Green Car Congress

On 15 Sep, NHTSA and the US EPA proposed a joint rulemaking on fuel economy and greenhouse gas emissions for light duty vehicles: an average new car 34.1 Three of the NHTSA scenarios for penetration of technologies for light trucks for MY 2016. This reduces pumping losses at lighter loads in comparison to a larger engine.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

Appendix B: Car of the Future: A Comparison of Alternative Vehicles. It is alarming to see comparisons of the Chevrolet Volt PHEV with battery electric cars when the comparison focuses only on the electric range and ignores the other important differences. More information on e-mile comparisons is given by Reference Nº 2.

Greenlings: Benefits of charging stations vs. battery swaps vs. home charging

Tony Karrer Delicious EVdriven

Hit the jump for a comparison that includes plenty of pics and video. Most charge points available today take much longer to re-energize batteries than it does to fill a gas-powered cars tank. Reply ↓ ↑ report 18 Efried 5:47AM (4/10/2009) I will hang a poster about the comparison at EVS24. not an issue.
