Combining infrastructures: H2 pipelines in cable routesmore
For the large-scale distribution of hydrogen in Germany, the Fachverband der Netzbetreiber (FNB) – the German Association of Network Operators – proposes to make modifications to the existing natural gas network as well as to a number of new construction projects.
A comparison of FNB’s proposed hydrogen network with underground cable projects in Germany shows that the routes for the direct current transmission lines, which are already in the planning stage, could be meaningfully used to complete the planned H2 pipeline network. In addition, this could increase the H2 transport capacities in a North–South direction to approximately 10 GWh/h.
In an initial study conducted by ILF Consulting Engineers, it became apparent that pipe laying is technically feasible within a large part of the route for the power transmission lines, with only a few sections leading to increased planning and construction costs. For the smallest part of the routes, a small-scale re-routing of the H2 pipeline is likely to be advisable for economic reasons. The next steps shall be the examination of the general conditions, especially with regard to the project’s chances of receiving authority approval and a detailed consideration of the technical feasibility.
