Distance-dependent energy demand as well as transport capacity of different (future) hydrogen (H2) distribution options - in gaseous form (GH2) through repurposed natural gas or new pipelines as well as in liquid form (LH2) via ship and truck - are analyzed based on technology perspectives, key scaling properties and performance potentials. As central result of thermodynamic analysis, the energy demand based breakeven distance for GH2 pipeline transport versus LH2 shipping and trucking is typically reduced by about 35 % to maximally several hundred kilometers, if GH2 transport proceeds through large repurposed instead of new steel pipelines. This stems from the underlying differences in pipes inner layer condition and resulting friction-induced pressure losses leading to enhanced energy demand for recompression along the transport path. Moreover, in reflection of the trade-off between energy demand and transport capacity and hence sensible transport range, a 10 % reduction in load capacity for repurposed pipelines is found to balance additional energy demand and differences in breakeven distance compared with new steel pipelines. Techno-economic consequences regarding the envisioned European Hydrogen Backbone including perspectives of composites technology for GH2 pipelines are discussed together with implications for favorable transport scenarios for the aviation sector, which for reasons of energy density typically requires the provision of liquid hydrogen for use as energy carrier on-board future aircraft.
