The collaboration between NOW and the German Energy Agency has resulted in a comprehensive study on the future supply of hydrogen refuelling stations in Germany through a hydrogen pipeline network. The study highlights the viability of a central hydrogen hub model on the hydrogen core network as a cost-effective and sustainable solution. By distributing hydrogen to nearby refuelling stations and optimizing processes like purification, this model enhances economic feasibility and efficiency. The techno-economic evaluation conducted in the study compares various connection options for hydrogen refuelling stations to the hydrogen core network, stressing the importance of a coordinated approach encompassing technological advancements, regulatory frameworks, and infrastructure planning. Key findings emphasize that hydrogen hubs can significantly reduce transport and processing costs, albeit posing technological challenges in hydrogen purification, which suggests the need for piloting the hub model. The study forecasts the transformation of over 9000 km of existing natural gas pipelines into the German H2 core network by 2025, necessitating an estimated investment of €19 billion by 2032. The study's recommendations echo the importance of synchronized planning between H2 networks and refuelling stations, identifying demand patterns in the transport sector, and developing efficient purification processes. Notable figures in the industry have lauded the study's insights, emphasizing the essential role of a cost-competitive hydrogen supply for the logistics sector's adoption of hydrogen vehicles. Overall, the study underscores the significance of the hub model in laying the groundwork for a successful transition to hydrogen-driven heavy-duty trucks and promoting a sustainable and efficient hydrogen infrastructure in Germany.
