One of the challenges associated with the use of hydrogen is its storage and transportation. Hydrogen pipelines are an essential infrastructure for transporting hydrogen from offshore production sites to onshore distribution centers. This paper presents an innovative analysis of the pressure drops, velocity profile, and levelized cost of hydrogen (LCOH) in various hydrogen transportation scenarios, examining the influence of pipeline type (steel vs. composite), diameter, and outlet pressure. The role of the compressor and the pipeline, individually and together, was assessed for 1,000 and 100 tons of hydrogen. Notably, the LCOH was highly sensitive to these parameters, with the compressor contribution ranging between 21.52% and 85.11% and the pipeline’s share varying from 14.89% to 78.48%. The outflow pressure and diameter of the pipeline have a significant impact on the performance: when 1,000 tons of hydrogen is transported, the internal pressure drop ranges from 2 to 30 bar and the flow velocity can vary between 2 and 25 m/s. For equivalent hydrogen quantities, the composite pipeline exhibits the same trends but with minor variations in the specific values.

与使用氢气相关的挑战之一是其储存和运输。氢气管道是将氢气从海上生产基地运输到陆上配送中心的重要基础设施。本文对各种氢气运输场景中的压降、速度分布和氢气平准化成本 (LCOH) 进行了创新分析，研究了管道类型（钢与复合材料）、直径和出口压力的影响。针对 1,000 吨和 100 吨氢气，分别和共同评估了压缩机和管道的作用。值得注意的是，LCOH 对这些参数高度敏感，压缩机的贡献范围在 21.52% 到 85.11% 之间，管道的贡献范围在 14.89% 到 78.48% 之间。管道的流出压力和直径对性能有显着影响：输送1000吨氢气时，内部压降范围为2至30 bar，流速可在2至25 m/s之间变化。对于等效氢气量，复合管道表现出相同的趋势，但具体值略有变化。
