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

Green Car Congress

In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas. This is especially important for assessing the GHG emissions of PHEVs.

Univ of Toronto study details impacts of interaction between driving patterns and electricity generation for WTW energy use and GHG emissions for PHEVs

Green Car Congress

WTW GHG emissions of vehicles across driving patterns and PHEV charging scenarios. Solid portions represent GHG emissions associated with gasoline propulsion. Patterned portions represent GHG emissions associated with electric propulsion. Solid left bar = hydro electricity scenario.) 100% coal (pulverized coal boiler).

Study finds PHEVs will reduce net emissions of CO2 and NOx; upward pressure on SO2

Green Car Congress

Net emissions resulting from the use of plug-in hybrid electric vehicles (PHEVs) depend on the efficiency of the conventional vehicle fleet; PHEV CD (all-electric, charge-depleting mode) efficiency; charging strategy; battery pack capacity; driving patterns; and generator mix used for charging. Scott Peterson, J.

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., In our base case, we assume average US values for emissions and damage valuation of electricity generation, oil refining, vehicle.

Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

WTW energy demand and GHG emissions for EV and PHEV drivetrains for various electricity sources; gasoline ICE vehicle is solid square, hybrid the hollow square. The study by a team at the Swiss Federal Institute of Technology Zurich, reported in the Journal of Power Sources , is novel in three respects, the researchers said.

Argonne releases GREET 2020

Green Car Congress

The GREET (Greenhouse Gases, Regulated Emissions, and Energy use in Transportation) tool provides a common, transparent platform for lifecycle analysis (LCA) of of the energy and environmental effects of a wide variety of transportation fuels and vehicle technologies in major transportation sectors (i.e., CO 2 -derived ethanol.
