The aim of this work is to explore the potential of coupling the sectors of private transport and electric energy production. Sixteen scenarios are developed to evaluate to what extent battery electric vehicles can compensate the fluctuations of renewable energies with regards to bidirectional charging. Four research questions, simplified here, are presented for this purpose: (F1) What energy storage potential is available in battery electric vehicles in Austria at the end of 2020? (F2) What energy storage potential is available in battery electric vehicles in Austria at the end of 2030? (F3) How many charging cycles of the battery electric vehicles occur per year and how high would the electricity storage capacity of all vehicles have to be in the hypothetical case that seasonal storage were to be targeted in 2030? (F4) To what extent can this energy storage potential theoretically compensate for fluctuations of renewable energies in 2030 to 2050? To answer these research questions, the battery electric vehicles registered in Austria are analyzed and scenarios regarding the future installed (lithium-ion) industrial battery quantity are discussed. To answer F3 and F4, the WAM+ scenario of the Bundesumweltamt is used and it is elaborated how much energy storage will be needed in the years leading up to 2050. This Data is combined with the results of F1 and F2 so F3 and F4 could be solved with a decision-tree algorithm. To discuss F1-F4, qualitative data sets are taken from the transport and energy sectors and get processed using mathematical functions. The Results of F1 will show an energy storage potential from 1910 MWh to 2451 MWh. For F2 this value, depending on the scenario, increased up to 32600 MWh. Research question F3 can be answered with 730 charging cycles and 3,78 TWh hypothetical seasonal storage and for F4, an average increase in annual coverage hours of 22,64 % is elaborated. The 108 results for F4 are in the range between 4,03 % and 28,40 %.
