H2Poseidon
H2Poseidon is a bidirectional pipeline designed for 100% hydrogen transport, set to complement the deployment of natural gas and other imported fossil fuels - a significant contribution to energy security and the achievement of the European Green Deal objectives.
An hydrogen pipeline from Greece to Italy and Europe
H2Poseidon extends for a total length of approximately 340 km, including 210 km offshore from Greece to Italy and about 130 km onshore from Otranto to Taranto, where it connects to the Italian hydrogen network. The initial transport capacity is expected to be around 90 GWh per day, equivalent to 9 billion cubic meters of hydrogen per year. At full capacity — depending on the development of the hydrogen market — the pipeline will be able to transport approximately 150 GWh per day, equivalent to 15 billion cubic meters annually.

The strategic role in distribution towards Europe
The infrastructure, promoted by IGI Poseidon, will be interconnected with the Ionian Energy Terminal, the EastMed pipeline, and the future Greek hydrogen network, enabling its transport towards Europe. Thanks to its strategic importance, in 2024 H2Poseidon was included in the Ten-Year Network Development Plan (TYNDP) of the European network.
