Abstract: The EU aims for complete decarbonisation. Therefore, renewable generation must be massively expanded, and the energy and exergy efficiency of the entire system must be significantly increased. To increase exergy efficiency, a holistic consideration of the energy system is necessary. This work analyses the optimal technology mix to maximise exergy efficiency in a fully decarbonised energy system. An exergy-based optimisation model is presented and analysed. It considers both, the energy supply system and the final energy application. The optimisation is using Austria as a case study with targeted renewable generation capacities of 2030.
