This contribution analyzes two different types of pipeline network topologies (namely, star and tree networks) and two different fluid flow models (linear and nonlinear) for a given hydrogen capacity scenario of electrical reconversion in Germany to analyze the impact of these simplifications.
Today, Linde has the largest liquid hydrogen capacity and distribution system in the world. We also operate the world''s first high-purity hydrogen storage cavern, coupled with an unrivaled pipeline network of approximately 1,000 kilometers
Therefore, based on the current design of state-of-the-art hydrogen pipelines and compressor stations, this current study aims to derive pertinent data for the development of a large-scale hydrogen pipeline network.
Hydrogen as a source of energy per se is a storage medium. Like natural gas, it can be stored in large underground storage facili-ties, transported to the end-user by pipeline, and even achieves a similarly high transport energy density due to its material properties.
A pan-European hydrogen infrastructure network – the so-called hydrogen backbone - is necessary to enable matching supply and demand across different regions and maximize the use of renewable energy resources.
Based on the advantages of existing infrastructure, blending hydrogen into natural gas pipeline networks is seen as a feasible solution for long-distance and low-cost hydrogen transportation.
The report emphasizes the need for an economic assessment, considering the opportunity costs associated with reduced energy transmission capacity and the steps required to prepare pipeline networks and end-use applications for hydrogen blending.

The infrastructure company Fluxys Belgium is preparing its pipeline network for transporting hydrogen and CO2. Sweco has been awarded the assignment to conduct a feasibility study and preliminary research into several hydrogen routes in Ghent and Antwerp.
For the purpose of designing a hydrogen pipeline network, an optimization-based method has been developed. The method considers the existing natural gas network as an underlying topology above which the hydrogen network is to be designed and allows for the conversion of natural gas pipelines.
Hydrogen is injected in a Natural Gas Pipeline network for blending and resale to conventional or dedicated applications as natural gas with a "renewable" component.

For transporting gaseous hydrogen over medium distances, large-scale transmission pipeline networks are considered to be an economically attractive solution. Nevertheless, for realizing the intended goal of sustainability, hydrogen transport via pipeline should be verified not only from an economic, but also an environmental perspective.
ster competition amongst them. Hence, it establishes hydrogen infrastructure as a viable energy transport solution within policy environments that are increasin
The pipelines carry pressurized hydrogen gas from the feed-in station to substations, where the gas is subsequently expanded and transferred to the distribution network. The operating pressure ranges between 16 and 100 bar. The diameter of hydrogen pipelines is typically between 400 and 1,400 mm (16 to 56″) .
By 2030, an initial hydrogen pipeline network of approximately 28,000 km will link first hydrogen valleys, renewable hydrogen supply regions and important industrial clusters. By then, it is assumed that the network will primarily consist of existing natural gas pipelines repurposed for hydrogen transport.
Apart from that, only small adjustments are required to minimize hydrogen embrittlement and qualify existing natural gas pipelines for hydrogen transmission, since such existing pipelines are often designed and installed in accordance with similar requirements and standards such as those for hydrogen pipelines , .
he tional Hydrogen Strategy’ (June 10, 2020), pp. 7, 132. Pipeline capacity when switching to hydrogenContrary to popular belief, the transport energy density f hydrogen is only slightly lower than that of natural gas. Therefore, the switch from natural gas to hydrogen has little
