In an open-access invited review for the Journal of the Electrochemical Society , Dr. Oliver Gröger ( earlier post ), Volkswagen AG; Dr. Hubert A. Gasteiger, Chair of Technical Electrochemistry, Technische Universität München; and Dr. Jens-Peter Suchsland, SolviCore GmbH, delve into the technological barriers for all-electric vehicles—battery-electric or PEM fuel cell vehicles. They begin by observing that the EU’s goal of 95 gCO 2 /km fleet average emissions by 2020 can only be met by means of extended range electric vehicles or all-electric vehicles in combination with the integration of renewable energy (e.g., wind and solar). Based on other studies, they note that without an increasing percentage of renewables in the European electricity generation mix, the only vehicle concept which could meet the 95 gCO 2 /km target is the pure battery electric vehicles. (Hydrogen produced via electrolysis using the EU mix or by natural gas reforming would exceed […]
