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.

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. coal, hydro, natural gas) on well-to-wheel (WTW) energy use and greenhouse gas (GHG) emissions of plug-in hybrid electric vehicles (PHEVs). Driving patterns affect the WTW performance of PHEVs in two ways, they found. Click to enlarge.

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.

Modelling the Impact of PHEVs on Ozone in Denver

Green Car Congress

Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. million vehicles and would have increased by 3 tpd from power plants.

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.

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.

Are EVs Charged Mostly By Coal Power in the US?

EV Adoption

One of the common arguments you hear from people in America who are not fans of the idea of electric vehicles is that they are mostly charged from electricity produced from coal power plants. Heavy Coal Using States Accounted for Only 10% of EV Sales in 2020. The argument that EVs are powered mostly from coal simply isn’t true.
