Fraunhofer analysis finds battery-electric trucks have energy cost advantage over hydrogen trucks

Green Car Congress

In a recent analysis, Fraunhofer ISI concludes that battery-electric drives will become established in heavy-duty applications in the commercial vehicle sector and that fuel cells will remain a niche application. The decisive factor for the switch to battery-electric vehicles is the energy cost advantage compared to hydrogen and diesel.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Lead author Aniruddh Mohan and colleagues wanted to develop a method that evaluated the life-cycle costs and benefits for two battery-powered ridesource fleets and a gasoline-powered one. The analysis indicated that electrified fleets had 40-45% lower greenhouse gas costs per trip compared to the gasoline-powered version.
