This report describes the POTEnCIA CETO 2024 Scenario, which showcases how the deep decarbonisation of the EU’s energy system can be achieved from an energy technology perspective in alignment with the general objectives of the European Climate Law. The scenario has been modelled using the JRC-in-house developed POTEnCIA model in order to provide a detailed explanation of how the different technology pathways were derived for the accompanying CETO 2024 technology reports. The report summarises the underlying methodology of the POTEnCIA model as well as the key policies and data inputs used to develop the POTEnCIA CETO 2024 Scenario. The results show that the deployment of clean energy technologies such as renewable energy sources, electrification, and carbon capture, utilisation and storage technologies are critical for achieving the EU’s climate targets.
