Beyond sector coupling: Utilizing energy grids in sector coupling to improve the European energy transition

Sector coupling and system integration are key concepts in the energy transition from fossil fuels to fully decarbonized energy systems based on renewable energy. An intelligent use of sector coupling – such as that expressed in the concept of a smart energy system –accommodates for the identification of a more energy-efficient and affordable green transition. However, these benefits are often not fully identified in scenario modelling for the simple reason that not all energy systems analysis tools are equipped to do so. Here, we use the EnergyPLAN tool to replicate the EU Baseline and 1.5 TECH scenarios of the report “A Clean Planet for All”, which we then compare to a smart energy systems scenario for Europe. Due to its focus on sector coupling, we show how such a smart energy Europe scenario can be more energy efficient and affordable than the other scenarios.
