Sector coupling links power and transport, and a prior study reviewed literature and performed a preliminary global, EU, and German analysis of this integration. This paper proposes a modelling framework for sector coupling in Germany. Using the METIS platform, the authors model Germany with a high renewable energy share, a significant fleet of fuel cell vehicles, and a dedicated hydrogen pipeline, detailing sector‑specific assumptions. The analysis shows how power surplus can be converted to hydrogen via electrolysis, the pipeline’s utilization, and economic implications, providing a foundation for future international studies.
“Linking the power and transport sectors—Part 1” describes the general principle of “sector coupling” (SC), develops a working definition intended of the concept to be of utility to the international scientific community, contains a literature review that provides an overview of relevant scientific papers on this topic and conducts a rudimentary analysis of the linking of the power and transport sectors on a worldwide, EU and German level. The aim of this follow-on paper is to outline an approach to the modelling of SC. Therefore, a study of Germany as a case study was conducted. This study assumes a high share of renewable energy sources (RES) contributing to the grid and significant proportion of fuel cell vehicles (FCVs) in the year 2050, along with a dedicated hydrogen pipeline grid to meet hydrogen demand. To construct a model of this nature, the model environment “METIS” (models for energy transformation and integration systems) we developed will be described in more detail in this paper. Within this framework, a detailed model of the power and transport sector in Germany will be presented in this paper and the rationale behind its assumptions described. Furthermore, an intensive result analysis for the power surplus, utilization of electrolysis, hydrogen pipeline and economic considerations has been conducted to show the potential outcomes of modelling SC. It is hoped that this will serve as a basis for researchers to apply this framework in future to models and analysis with an international focus.
