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.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

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. Patterned portions represent GHG emissions associated with electric propulsion. Solid left bar = hydro electricity scenario.) Driving patterns affect the WTW performance of PHEVs in two ways, they found. 100% natural gas (combined cycle).

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.

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

Green Car Congress

The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.)

Los Angeles to lease 160 BEVs, 128 PHEVs as part of commitment to 50% EV purchases by 2017

Green Car Congress

The program commits city departments to the leasing of pure battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) to replace aging city vehicles, including those with conventional internal combustion engines. The LADWP will lease 44 BEVs and 113 of the PHEVs. per mile for EVs vs. $0.37
