Sector-Coupling of a Highly Renewable German Energy System — •Clara Steinebach, Tom Brown, and Stefan Schramm — Frankfurt Institute for Advanced Studies, Frankfurt, Germany

Energy consumption is made up of four major sectors -- electricity, heat, transport and industry, each of which contribute about one-fourth of the final energy consumption in Europe. In order to reduce the CO2 emissions, synergies from coupling these sectors have to be investigated and used. The coupling of electricity to other sectors, such as transport and heating, offers new cost-effective options for evening out seasonal- and synoptic-scale fluctuations of renewables like wind and solar, particularly given the low cost of long-term thermal energy storage. This work focuses on the German energy system. The cost-optimal low-carbon system is calculated, incorporating electricity demand, electrified transport and partially-electrified heating demand. By coupling these energy sectors and using battery storage from battery electric vehicles (BEV) and the thermal storage possibilities from the heating sector, stationary electricity storage needs can be reduced or even be eliminated.
