Tenaris, IGI Poseidon Partner to Advance Offshore Hydrogen Pipeline Testing
Tenaris and IGI Poseidon, a joint venture between Greece’s DEPA International Projects and Italy’s Edison S.p.A., are collaborating to address key challenges in transporting hydrogen via ultra-deep offshore pipelines.
The partnership focuses on two critical issues: safely transporting hydrogen under harsh conditions and ensuring the economic competitiveness of transmission costs. As hydrogen gains recognition as a vital part of the transition to a low-carbon energy future, its use as a carbon-free energy vector offers significant potential. However, its tendency to embrittle steel under certain conditions presents a unique challenge.
To tackle this, IGI Poseidon and Tenaris are conducting qualification testing for offshore high-pressure pipelines, drawing on their combined expertise in energy infrastructure and pipeline technology.
“Our target in IGI Poseidon has always been to develop infrastructure for a diversified and competitive energy future,” said Fabrizio Mattana, CEO at IGI Poseidon. “This partnership is a natural extension of our vision, contributing to Europe’s ambitious climate goals.”
Konstantinos Xifaras, Chairman of the Board at IGI Poseidon, added, "This collaboration is a significant step towards realizing a sustainable energy future. By combining our expertise with Tenaris' advanced materials technology, we are reinforcing our commitment to hydrogen transportation and innovation."
Innovation is central to Tenaris’s approach to advancing energy technologies. Philippe Darcis, Pipeline Technology Senior Director at Tenaris, stated, “Contributing to research on material performance in hydrogen environments is key to our strategy. We are leveraging our expertise and R&D capabilities to support the development of next-generation hydrogen transportation networks."
The joint initiative, launched in 2024, includes rigorous testing of high-strength material (X70) and girth welding under high-pressure conditions, simulating the transport of pure hydrogen via offshore pipelines IGI Poseidon designed for natural gas.
The testing is being carried out in specialized laboratories in Italy and the U.S., focusing on fracture toughness testing at various pressure levels, up to 330 bar, in line with the latest industry standards. This will assess the impact of increased pressure on pipelines transporting 100% hydrogen, helping define the operational conditions necessary for hydrogen readiness. Preliminary results are expected in 2025.
