The reduction of greenhouse gas emissions by 80 % until 2050 in comparison to 1990 is one goal postulated by the European Union. Thereby, the share of renewable energies contributing to the electricity mix needs to be increased further. Considering that the goal to reduce greenhouse gas emissions applies nationwide it is not enough to concentrate actions only on emissions from electricity generation. Therefore, this project focusses on interactions between the three main sectors (electricity, heat and mobility) regarding CO2 emissions and the need for energy storage in the future.

Overview of the energy system

At present the share of renewables is quite low in the heat and mobility sectors, compared to the electricity sector. To reach the goal of 80 % CO2 reduction, an increased renewables share in these sectors is essential. Through interaction between the three sectors synergy benefits can arise. Solutions like heat pumps or e-mobility are examples of how CO2-emissions can be reduced by combining electricity generation with other sectors.

The present part project here deals with the interaction effects between electricity generation and the mobility sector. The German fleet of vehicles and the corresponding energy demand are simulated. Different scenarios are evaluated in line with the emission goals stipulated for 2050; the expectations in their specific development are taken into consideration. Time series for every evaluated scenario give specific energy demand profiles, to highlight the linking of these sectors with, for example, energy storage through batteries or power-to-gas. The resulting impacts on the electricity sector are then considered.
