New study on the potential role of hydrogen in the future Swiss electricity system.
Hydrogen and e-fuels and their potential role in future energy systems are hotly debated topics. Using The modelling platform Nexus-e, a team of researchers at the Energy Science Center at ETH has looked at the potential role of imported or domestic hydrogen or e-methane for the Swiss electricity system.
New scenarios based on cooperation with Energy Infrastructure Partners
Energy Infrastructure Partners and the Energy Science Center at ETH Zurich have signed a research collaboration. In this collaboration, EIP and ESC under the lead of Dr. Marius Schwarz have developed scenarios for the future of Switzerland’s electricity system and tested several shock scenarios. Results show that reducing grid transfer capacities to 30 percent in 2050 as an unforeseen shock or drastically reducing the availability of nuclear power plants in France as the same type of shock does not result in supply issues. Only the scenario forcing Switzerland to keep a balanced winter trade balance results in supply issues.
Solar PV will be a key technology of the Swiss energy transition according to new model intercomparison study
Models are valuable tools to assess potential future pathways of the energy transition. Such models can diverge in their objective functions, data inputs and assumptions. Multi-model analyses can provide important insight into such divergences and similarities and provide more robust assessments. In a recent study, we have compared Nexus-e, EXPANSE and OREES, three electricity system…

Energy blog: Nexus-e and modeling for policymakers
Computational models can provide technical analysis to objectively evaluate the impact of energy policies. But why are they rarely used in public policymaking? Unclear quality of the input, non-transparent methodology, lack of validation, neglecting behavioural irrationality, and oversimplification are some of the barriers. Nexus-e makes a first step to tackle these challenges.
