Corinth Pipeworks confirmed that the selected materials and pipeline infrastructure are suitable for the transport of 100% hydrogen at 200 bar pressures. Specifically, they tested the 30” Sawl X70 linepipe, a high-strength steel pipe used in large-scale offshore infrastructure.

The engineering team tested girth welds under high hydrogen pressures, gaining insights into pipe performance. They conducted fracture toughness, slow strain rate tensile testing, fatigue lifecycle modelling for 50+ years, and an Engineering Critical Assessment (ECA), simulating the pipeline’s long-term operational conditions.

IGI Poseidon reported that testing confirmed the EastMed pipeline’s functionality for over 50 years of hydrogen transport.

H2 View understands the network will link Israel, Cyprus, Greece, and Italy, with capacity to import hydrogen from the Middle East and Africa.

The Greek-Italian joint venture, equally owned by DEPA International Projects S.A. and Edison S.p.A., specialises in natural gas infrastructure but is pursuing the hydrogen pipeline in alignment with Europe’s energy transition goals and has been granted IPCEI status.

On LinkedIn, IGI Poseidon stated, “These findings validate the readiness of steel linepipe technology to meet future offshore hydrogen transportation demands, in a context where international design codes are under definition.”

As IGI Poseidon develops a dedicated hydrogen pipeline network, the Eastern Mediterranean Gas Forum’s recent findings on hydrogen blending highlighted the region’s potential as a global energy hub.

According to a report from the non-profit organisation, blending up to 20% hydrogen into existing natural gas pipelines in the eastern Mediterranean region is “technically feasible” and can serve as an interim solution while dedicated hydrogen infrastructure is developed.
