Nexus-e: Integrated Energy Systems Modelling Platform

Can renewables replace nuclear power? Will energy solutions be centralized or distributed? Nexus-e applies a holistic view of the Swiss energy system for questions like these.

The decision to realize the Swiss Energy Strategy 2050 has wide-ranging implications for the entire energy-economic system. Models can enable system thinking, however, combining interdisciplinary models to study the interactions between different parts of the energy system is challenging. 

The Nexus-e project aims to fill this gap. The project is an initiative of the Energy Science Center of ETH Zurich and started in 2014. Nexus-e is a platform that links modules through well-defined interfaces, allowing us to analyze the future developments of the energy system holistically. Nexus-e combines energy systems and macroeconomic models to represent a much broader scope of the energy-economic system. Currently, we use the Nexus-e platform to analyze the role of hydrogen and carbon transportation infrastructure in Switzerland and how they support the transition towards a carbon neutral energy system. We assess the impacts of investment necessary for such a transition on the electricity market, electricity grid security, and the wider economy.

In the future, we aim to expand the Nexus-e platform by connecting more groups and researchers at ETH Zurich, collaborating with other universities and industry partners, and adding new modules to the platform, for example, to include the electrification of the transportation and building sectors.
