The TEN-E (Trans-European Energy)(2022) and TEN-T (Trans-European Transport)(2024) regulations recognise hydrogen as a key infrastructure priority. TEN-E includes hydrogen transmission pipelines, reception terminals, storage facilities and electrolysers as Projects of Common Interest (PCIs) and Projects of Mutual Interest (PMIs), facilitating cross-border networks, streamlining permitting and providing access to funding. Projects of Common Interest (PCIs) are key cross-border infrastructure projects that link or significantly impact the energy systems of two or more EU countries. Projects of Mutual Interest (PMIs) link energy infrastructure of one or more EU countries with neighbouring (non-EU) countries. TEN-T supports the deployment of hydrogen refuelling stations along the TEN-T road network, enabling integration into Europe’s future mobility networks.
EU countries have until mid-2026 to transpose the new rules into national law. Once transposed, these will facilitate the uptake of renewable and low-carbon gases, including hydrogen, while ensuring security of supply and affordability of energy for all EU citizens.
