Abstract

The electrification of automobile represents today the main research track for both industry and academia towards a sustainable mobility. The use of electric energy as an energy carrier for passenger cars has the potential to contribute towards the reduction of pollutant emissions in urban areas and, according to the adopted generation mix, also to GHG emissions from transportation. Moreover, new development opportunities are emerging, based on the growing interdependency between the transportation sector and the stationary electric power generation. Such an aspect is of particular relevance today due to the upcoming introduction of plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs), particularly with the perspective diffusion of Vehicle to Grid (V2G) technologies. Therefore in the current paper a thorough analysis is conducted to assess, on one hand, the impact of vehicle electrification on electric grids and their related infrastructures, and, on the other, on its potential contribution to GHG emission reduction. Such an analysis covers the timeframe 2011-2050, thus allowing to quantitatively assess if the environment friendliness of both PHEV and BEV will be enough contributing to meet the objectives recently established by official agreements among governments, as well as by reference research consortia, such as the International Energy Agency. The expected penetration of both PHEV and BEV is modeled along with the well to tank and tank to wheel GHG emissions, aiming at providing the needed input data to the above-described scenario analysis. Particularly, a longitudinal vehicle model is adopted to precisely estimate electric vehicle energy consumptions and related GHG emissions as function of powertrain configuration, dimensions and mass. The analysis was run on several countries, thus providing useful outcomes to assess the suitability of given energy mix to fully exploit vehicle electrification. Such indications will therefore be useful to determine to which extent progressive decarbonization of current grids is required to meet the GHG reduction target by 2050.
