Scenario-Based Modeling and Assessment of the Future European Hydrogen Backbone

Year: 2026

Abstract: The evolving hydrogen transmission network is a key component of Europe’s energy transition. This study assesses whether the planned European hydrogen transmission grid can accommodate projected regional supply and demand in 2030, 2040, and 2050. Scenario data from the TransHyDE System Analysis project are combined with GIS-based network models and European-scale hydraulic simulations. The modeled topology integrates the European Hydrogen Backbone and the German hydrogen core network. The results indicate that, in 2030, the still-fragmented network can satisfy peak regional demand. By 2040, the grid develops into a largely meshed system, although elevated pressure levels occur in Spain and Italy because of regional supply–demand imbalances and high hydrogen imports from North Africa. The southern European pipelines and the interconnections between the Iberian Peninsula and Central Europe therefore appear insufficiently dimensioned under the investigated scenario. These effects become more pronounced in 2050 as hydrogen demand and imports increase. The findings indicate that additional transport capacity and strengthened cross-border interconnections may be required to ensure the reliable operation of the future European hydrogen network.
