The buildout of the European Hydrogen Backbone (EHB) network is well underway. Transmission System Operators (TSOs) are planning to make substantial investments and can point to tangible progress on corridor projects. All five envisioned corridors have projects currently in progress, with a clear majority of EHB member TSOs working on implementation and producing real progress in their countries. This report highlights a set of 40 concrete projects managed by the EHB’s TSO members, representing 31.500 kilometres of hydrogen pipelines with expected commissioning prior to 2030.
