The Federal Ministry for Economic Affairs and the Federal Network Agency have integrated the Hamburg Hydrogen Industry Network (HH-WIN) into Germany's 10,000-kilometre national hydrogen core network. This move provides financial certainty for further development of HH-WIN, with a planned network length of around 60 kilometres by 2032. The integration highlights the bridging function of Hamburg's hydrogen pipelines in the nationwide hydrogen economy. The core network's development is crucial for implementing the national hydrogen policy and achieving a rapid market launch. The Energy Industry Act mandates the connection of hydrogen production and import facilities to customers, with efforts to establish a consistent national grid fee to support network construction. The funding strategy for HH-WIN ensures investment stability beyond its 2027 commencement date. Hamburg is expected to become a vital hub for the northern hydrogen economy, with plans to deliver hydrogen by the end of 2027. The collaboration between HPA and MPA further signifies the region's commitment to digitization, decarbonisation, and cyber security.
