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

However, the report concludes, initiating deployment of these technologies is urgent; actions taken—or not taken—between now and 2020 to develop and demonstrate several key technologies will largely determine the nation’s energy options for many decades to come. emissions, according to the report.

CMU study finds that HEVs and PHEVs with small battery packs offer more emissions and oil displacement benefits per dollar spent than large pack PHEVs and BEVs; policy implications

Green Car Congress

Strategies to promote adoption of hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) with small battery packs offer more social benefits (i.e., We find that, in the base case, plug-in vehicles (PHEVs and BEVs) may produce more damage on average than today’s HEVs. Michalek et al. are also substantial.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

This is especially important for assessing the GHG emissions of PHEVs. For battery EVs, the GHG emissions for “fuel/electricity” production are dominated by the coal and natural gas used in electricity generation. BEVs powered by renewable electricity and FCEVs fueled by green hydrogen are the only two technology pathways that qualify.

MIT, Ford researchers find lightweight conventional vehicles could have lower lifecycle GHG impact than EVs depending upon location

Green Car Congress

Their paper is published in the ACS journal Environmental Science & Technology. Regional differences in climate, electric grid burdens, and driving patterns compound to produce significant regional heterogeneity in the GHG benefits of electrification. We show that lightweighting further accentuates these regional differences.

University of Calgary Study Finds Large-Scale Adoption of PHEVs in Alberta Could Support Wind Power; PHEV GHG Benefits Range from 40-90% in Emissions Reduction

Green Car Congress

The environmental benefit of a large-scale deployment of plug-in hybrid electric vehicles (PHEVs) in the Canadian province of Alberta could vary significantly, ranging from a 40% to a 90% reduction in greenhouse gases, according to a study by electrical engineers at the University of Calgary’s Schulich School of Engineering.

Royal Academy of Engineering Report Says EV Success Depends on Low-Carbon Electricity, Universal Broadband Provision and Smart Grids

Green Car Congress

The introduction of electric vehicles on a large scale in the UK can only have a beneficial effect on CO 2 emissions if low-carbon electricity, universal broadband provision and smart grids are in place to support the transition, according to a new report published by the UK Royal Academy of Engineering.
