PublicationFuture regional distribution of electric vehicles in Germany( 2020)Electrification as an option to decarbonize road transport leads to an increasing number of electric vehicles in Germany. However, the stock of electric vehicles is not evenly distributed regionally. The local distribution of electric vehicles is particularly important from an energy system perspective in order to be able to estimate future grid loads. Here, we use multiple linear regression to distribute a German-wide market diffusion of electric vehicles to 401 NUTS3-areas in Germany. Current regional vehicle stocks and regional development data (e.g. population, income, and spatial structure) are used as independent variables. We combine these variables with forecasts for spatial development and obtain a regionalized electric vehicle market diffusion for Germany. First results suggest a concentration of BEV and PHEV stocks in southwestern Germany and in large cities in the medium-term future.

PublicationMarket potential of catenary hybrid electric trucks in different world regions( 2019)Kluschke, PhilippCatenary hybrid electric vehicles (CHV) are one solution for a decarbonization of heavy-duty transport. To this point, research focuses on Germany and Sweden while other regions with large amounts of trucks are neglected. In this paper, the economic market potential of CHV in Europe, the US, China and India are analyzed. We find high market shares for CHVs with diesel engine for large parts of the considered markets.

PublicationWhat is the best alternative drive train for heavy road transport?( 2017)Kühn, AndréAmbitious long-term green house gas (GHG) emission targets require decarbonisation of the transport sector. For road transport, passenger cars with internal combustion engines need to be replaced by electric vehicles. However, despite its growing share of transport's CO2 emissions, no clear solution presents itself for CO2 emission reduction on heavy road transport. Potential CO2 free options include direct electrification of trucks via batteries, over-head power lines, hydrogen and other power-to-X fuels from renewable electricity. Here, we compare these options with respect to their degree of technological readiness, costs and CO2 reduction potentials. We use cost assumptions and cost reduction potentials from available literature sources and combine them with today's heavy truck usage data for Germany in 2030. Our results show that the high efficiency in direct usage of electricity from overhead cables implies less installation of additional renewable power compared to fuel cell electric vehicles. Both could be good long-term solutions but require a massive initial infrastructure investment.
