Ali Darudi joins the Energy Science Center as Technical Lead for Nexus-e

In May 2025, Dr. Ali Darudi joined the Energy Science Center (ESC) as Technical Lead for the Nexus-e group. The ESC is pleased to welcome Ali to its team!

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.

Swiss Electricity Supply after the “Mantelerlass” – Quo vadis? A perspective on Nuclear Power

In this study, we assess the role of the existing and new nuclear power plants for the Swiss electricity system. We use the Nexus-e modeling platform to develop three scenarios with different operating time of existing and construction of new nuclear power plants.

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…
