Tenaris and IGI Poseidon, a joint venture with Greek energy company DEPA International Projects and Italian Edison, are collaborating to enhance hydrogen transportation through offshore pipelines.
Their combined expertise aims to address safety challenges in severe conditions while keeping transmission costs economically viable. As hydrogen emerges as a key player in transitioning to a low-carbon future, its integration into existing energy infrastructure requires overcoming the challenge of its tendency to embrittle steel.
IGI Poseidon and Tenaris are conducting qualification tests focusing on high-pressure offshore pipelines. By pooling their skills in energy infrastructure and pipe technology, they aim to pave the way for this emerging green energy solution. Fabrizio Mattana, CEO of IGI Poseidon, emphasized their dedication to developing infrastructure for diversified energy, aligning with Europe’s climate objectives.
Chairman Konstantinos Xifaras highlighted the partnership’s significance in advancing sustainable energy. Combining IGI Poseidon’s expertise with Tenaris’s material technology strengthens their commitment to hydrogen innovation. Tenaris, with its focus on research and development, supports the evolution of energy technology crucial for hydrogen transport.
The initiative began in 2024, involving testing high-strength X70 material and girth welding under high-pressure conditions. These tests simulate the transport of pure hydrogen via offshore pipelines originally meant for natural gas. Conducted in Italy and the US, the tests assess fracture toughness under pressures up to 330 bar, adhering to industry standards. This testing evaluates the impact of transporting 100% hydrogen, refining operational conditions for future readiness. Results are expected in 2025.
