National Research Council Report on Americas Energy Future Highlights Vehicle Efficiency Technologies, Conversion of Biomass and Coal-to-Liquids Fuels, and Electrifying the Light Duty Fleet with PHEVs, BEVs and FCVs

Green Car Congress

Estimates of potential for gasoline consumption reduction in the US light duty fleet in 2020 and 2035 relative to 2007. Improvements result from an optimistic scenario achieving doubling of new vehicle fuel economy in 2035 from today’s value. Developing technologies for the conversion of biomass and coal-to-liquid fuels.

Study projects emission impacts of inexpensive, efficient EVs: 36% further reduction in LDV GHG by 2050, or 9% economy-wide

Green Car Congress

A new study by researchers at the University of Colorado at Boulder projects the emission impacts of the widespread introduction of inexpensive and efficient electric vehicles into the US light duty vehicle (LDV) sector. output of mining or importing technologies) to conversion or process technologies (e.g.,

U. Mich study: natural-gas-based ICE, BEV and FCV all show promise for environmental benefits relative to conventional ICE

Green Car Congress

Qiang Dai and Christian Lastoskie found that BEVs and FCVs in particular offer significant reductions in greenhouse gas emissions, especially if carbon capture and sequestration (CCS) technologies are implemented at the fuel conversion facilities. Their study appears in the ACS journal Energy & Fuels. … —Dai and Lastoskie.

NRC report concludes US LDVs could cut oil consumption and GHGs by 80% by 2050; reliance on plug-ins, biofuels and hydrogen; strong policies mandatory

Green Car Congress

Achieving those goals will will be difficult—but not impossible to meet—and will necessitate a combination of more efficient vehicles; the use of alternative fuels such as biofuels, electricity, and hydrogen; and strong government policies to overcome high costs and influence consumer choices.

Plug-In Hybrids (or Plugin Hybrids)

Tony Karrer Delicious EVdriven

Its like having a second fuel tank that you always use first -- only you fill up at home, from a regular outlet, at an equivalent cost of under $1/gallon. But when you do, your car essentially becomes an electric vehicle with a gas-tank backup. Lifetime service costs are lower for a vehicle that is mainly electric. The GREET 1.6

Technology warming potential (TWP) for three sets of natural gas fuel-switching scenarios. (A) 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.
