As part of the current Delegated Act, the European Commission has published the second list of Projects of Common Interest (PCI) and Projects of Mutual Interest (PMI) under the revised TEN-E regulation. With the publication of the new list, the strategic importance of the SoutH2 Corridor as one of Europe’s key hydrogen infrastructure initiatives is reaffirmed with the inclusion of all individual TSO projects that are part of the initiative.

PCIs play a central role in closing infrastructure gaps in the European energy network and demonstrate clear economic, environmental, and social benefits for the EU. The approximately 3,300-kilometre-long corridor will establish one of the most important European import routes for renewable hydrogen from North Africa and the Southern Mediterranean.

The SoutH2 Corridor is a joint initiative formed by the international transmission system operators bayernets, Gas Connect Austria (GCA), TAG GmbH, and Snam Rete Gas (Snam), which are jointly developing a cross-border hydrogen backbone to enable large-scale hydrogen imports to Central Europe.
The SoutH2 Corridor consists of four coordinated PCI projects:

  • “HyPipe Bavaria – The Hydrogen Hub” (bayernets GmbH)
  • “H2 Backbone WAG + Penta-West” (Gas Connect Austria GmbH)
  • “H2 Readiness of the TAG Pipeline System” (TAG GmbH)
  • “Italian H2 Backbone” (Snam Rete Gas)

Additionally, the North-Africa H2-Backbone — the offshore section from Cap Bon (Tunisia) to Mazara del Vallo (Italy) developed by SeaCorridor — has been included in the list as a Project of Mutual Interest (PMI). This designation establishes a crucial link between hydrogen production hubs in North Africa and the SoutH2 Corridor network.

With its renewed PCI status, the SoutH2 Corridor continues to be a cornerstone of Europe’s emerging hydrogen infrastructure, supporting security of supply, industrial decarbonisation and the creation of a competitive European hydrogen market.
