Resilient (Resilient Energy System Infrastructure Layouts for Industry, E-Fuels and Network Transitions)

About

The energy transition faces many uncertainties, yet planning tools are often deterministic. Our proposal aims to develop the first truly multi-vector energy infrastructure planning tool that represents this uncertain environment at regional, national, and European levels.

We will build on the widely used, open-source sector-coupled energy planning tool PyPSA-Eur, by adding stochastic optimization capabilities and a deeper representation of industry transformation, e-fuel conversion, biomass, and carbon capture infrastructure.

Our analysis will consider uncertainties such as fuel and technology costs, hydrogen availability, network expansion delays for electricity, hydrogen, and carbon dioxide, value chain restructuring in industry, imports of e-fuels and secondary materials, renewables build-out, and social acceptance. Additionally, we will explore novel computational techniques to efficiently address stochastic problems.

For this project, we have assembled a team of leading academic researchers and industry need-owners at the forefront of energy system modeling. We will demonstrate our tool’s capabilities through case studies on resilient infrastructure planning in France, Germany, Sweden, and Finland.

To maximize impact, we will organize workshops and training events involving a broader circle of need-owners and stakeholders, ensuring the wide adoption of project results.
