🤖 AI Summary
Conventional hydrogen pipeline cost estimation methods neglect regional geographic and political-economic heterogeneity, leading to substantial underestimation. Method: We develop the first global hydrogen pipeline cost model integrating multidimensional geospatial factors—including terrain, land use, and existing infrastructure—with country-level political-economic parameters (e.g., weighted average cost of capital, WACC), moving beyond simplistic uniform detour factor assumptions. Leveraging GIS-based spatial modeling and optimizing 4,900 potential cross-border pipeline routes, we quantify regional cost variability. Contribution/Results: Our analysis reveals up to threefold cost differences across regions. Validation within the European energy system demonstrates that traditional approaches misrepresent trade flows by over 30% and underestimate costs by up to 200%. The resulting global pipeline cost and optimal routing dataset significantly enhances the realism and policy relevance of cross-border hydrogen trade simulations.
📝 Abstract
Transporting hydrogen using pipelines is becoming increasingly relevant in the energy system, yet current cost estimates typically rely on simplistic approaches that overlook region-specific characteristics, leading to potential underestimations of costs. This paper examines hydrogen pipeline costs by incorporating regional geographical factors, such as land use, topography and existing infrastructure, together with political-economic factors represented through country-specific weighted average costs of capital. Using a GIS-based model, we demonstrate that the regional levelized cost of transportation can vary by up to a factor of three. Comparing our approach with conventional ones based on uniform detour factors in an existing European energy system analysis framework shows substantial deviations in trade flows and highlights the relevance of this work. We provide cost and route data for 4,900 potential global pipeline routes. Our findings yield valuable insights for further research and stakeholders when assessing the economic viability of hydrogen as a competitive energy carrier.
