240 ExpertiseVehicles 116 (2018) Heft 7 Boundaries and potentials of a European strategy to decarbonize freight transport Michael Lehmann, Erlangen (DE); Dominik Räder, Heidelberg (DE) In order to reach the GHG (greenhouse gas) reduction goals the traffic sector needs to be decarbonized rapidly. For road freight electric road systems such as trucks supplied by overhead contact lines are a viable technical option. As decarbonization of traffic and energy sectors are intertwined this essay studies strategic approaches in European lead markets to derive guidelines to jointly achieve the goals set. GRENZEN UND POTENZIALE EINER EUROPÄISCHEN STRATEGIE ZUR DEKARBONISIERUNG DES GÜTERVERKEHRS Zur Erreichung der Klimaschutzziele muss auch der Verkehrssektor zügig dekarbonisiert werden. Für den Straßengüterverkehr stellt dabei die Versorgung von Lkw über Oberleitungen eine einsatzbereite Technologieoption dar. Da die Dekarbonisierung von Verkehrs- und Energiesektor eng miteinander verbunden sind, untersucht dieser Beitrag strategische Lösungsansätze in europäischen Leitmärkten, um daraus Kernelemente einer gemeinsamen Strategie abzuleiten. LIMITES ET POTENTIALITÉS D´UNE STRATÉGIE EUROPÉENNE DE DÉCARBONISATION DU TRANSPORT DE FRET Dans le but d’atteindre les objectifs de réduction d’émission des GES (gaz à effet de serre), le secteur du transport nécessite une rapide décarbonisation. Pour le transport marchandises routier, l’alimentation électrique de camions par lignes aériennes de contact représente une solution technologique réaliste. Par le fait que dans le domaine de la décarbonisation les secteurs du transport et de l’énergie sont intimement liés, cette contribution étudie les approches stratégiques sur les marchés porteurs européens pour en définir les lignes directrices et atteindre conjointement les objectifs fixés 1 Current status of the electrification of the road freight transport Beginning with the research project ENUBA, the eHighway system for the electrification of heavy road freight traffic has been tested and further developed since 2010 on a private track in Germany and since 2016 on two public roads in Sweden and California. In Germany two field-tests on public roads funded by BMU are being built and one further is being planned [1]. Table 1 gives an overview of the tracks and the hybrid-trucks used for the overhead line operation. Figures 1 to 3 show the vehicles and infrastructure of the tracks that have been put in operation. In total, about 35 km of overhead line have been put in operation or are being planned and constructed. As of 2018, eight tractor trucks or articulated trucks have been equipped with different development stages of pantographs and various hybrid drive concepts. The German Federal Environment Agency (UBA) study “Climate Protection Contribution of the transport sector” states that in order to achieve the crosssector climate protection target for the year 2050, of minus 95% CO2 emissions compared to the reference year 1990, an almost complete decarbonization of road freight transport is required [2]. Therefore the environmental assessment of the electrification of road transport is closely linked to the economic assessment and comparison with the other options for action, such as electricity-based, synthetic liquid fuels or gases. The follow-up study by the UBA compares the cumulative differential costs of the different technology options for decarbonizing heavy road freight transport up to the year 2050 as a whole and separately for the areas of energy supply, infrastructure and vehicle procurement [3]. Figure 4 illustrates the role of electrification of road freight transport as the basic technology for decarbonizing the transport sector, which is by far the most economical option for action. Thereby the examined scenario E+ plans to electrify the 4000 most frequently used kilometers of german Bundesautobahn with overhead catenary infrastructure. b Probeheft zur Ansicht
