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

Green Car Congress

First, it considers the performance of both mature and novel hydrogen production processes, multiple electricity generation pathways and several alternative drivetrains. Third, the analysis offers a novel comparison of drivetrain and energy carrier production pathways based on natural resource categories. Click to enlarge. 2013.10.043.

MIT study finds including non-CO2 emissions from synthetic aviation fuel in lifecycle analysis of climate impact can lead to decrease in relative environmental merit; need for a holistic analysis framework

Green Car Congress

An an example, they point out that an SPK fuel option with zero life cycle GHG emissions would offer a 100% reduction in GHG emissions but only a 48% reduction in actual climate impact using a 100-year time window and the nominal climate modeling assumptions in the paper. —Stratton et al.

Analysis finds annual running cost of EVs less than ICE; but with purchase price factored in, it flips

Green Car Congress

EVs cost an average of $9,406 per year (including the purchase price) to run compared to $7,952 annually for gas vehicles (including the purchase price). per mile to fuel an electric vehicle; by comparison, the national average cost to fuel a gas vehicle is double at $0.06
