Tenaris Offshore Wind Initiatives for 2025: Key Projects, Strategies and Partnerships

Tenaris’s Strategic Pivot: From Pipe Qualification to Offshore Hydrogen Dominance

Industry Adoption: A Strategic Shift from Foundational R&D to Applied Offshore Expertise

Between 2021 and 2024, Tenaris laid the critical groundwork for its entry into the hydrogen economy. This period was characterized by foundational research and development, aimed at validating its core products for a new energy carrier. Key actions included a six-month trial using green hydrogen as a fuel at its Dalmine plant in Italy and the successful qualification of its line pipe for hydrogen transportation in 2022. The company also engaged in collaborative learning, joining the SafeH2Pipe Joint Industry Project in July 2024 to advance safety standards. This phase culminated in a pivotal partnership with IGI Poseidon in late 2024 to advance the transport of hydrogen in ultra-deep offshore pipelines. The focus was broad: testing, qualification, and establishing industry-wide best practices, demonstrating a clear intent to participate in the energy transition.

Starting in 2025, a distinct inflection point emerged. Tenaris’s strategy shifted from general readiness to targeted, application-specific deployment, particularly in complex offshore environments. The collaboration with IGI Poseidon deepened, with a February 2025 announcement focusing specifically on advancing “hydrogen readiness in offshore operations.” This signals a move from proving the material to engineering the solution for a specific, challenging use case. While not a hydrogen project, the supply of pipes for the Sakarya offshore gas field in March 2025 serves as a powerful commercial validation. It proves Tenaris’s capacity to deliver on large-scale, deep-water projects, a direct analogue for the future offshore hydrogen backbone. This evolution reveals a strategy to leverage its legacy oil and gas expertise as a critical advantage, creating a new opportunity to become the go-to supplier for the burgeoning offshore hydrogen infrastructure market.

Capital Allocation: Powering the Transition from Within

Tenaris’s investment strategy reveals a methodical approach to decarbonization, focusing heavily on securing renewable energy to power its own industrial operations. This builds a foundation of sustainability and operational efficiency that underpins its strategic pivot into clean energy technologies like hydrogen. By investing over $400 million in its own wind farms in Argentina, the company is not just offsetting its carbon footprint but also gaining direct, owner-operator experience in the renewable energy sector. This dual-purpose investment strategy strengthens its market position and ESG credentials, providing credibility as it engages with partners in the clean energy ecosystem.

Strategic Alliances: Building the Hydrogen Value Chain

Tenaris’s partnerships illustrate a clear trajectory from broad, exploratory research to focused, high-impact collaborations aimed at solving specific challenges in hydrogen transport. The early-stage research in Canada signaled interest, while joining the SafeH2Pipe JIP represented a move toward industry-wide standardization. The most significant development is the deepening partnership with IGI Poseidon, which has evolved from a general agreement to advance hydrogen transport to a specific focus on offshore readiness. This progression demonstrates Tenaris’s commitment to not just supplying pipes, but actively co-developing the solutions needed for Europe’s future hydrogen infrastructure.

Geography: Consolidating Focus on Europe’s Offshore Frontier

Between 2021 and 2024, Tenaris’s energy transition activities were geographically dispersed, reflecting a strategy of global operational decarbonization and foundational research. Investments in wind and solar assets were made in Argentina and Romania to power local mills, while a key hydrogen trial took place in Italy. At the same time, early-stage research into offshore wind concepts occurred in Canada. This broad footprint established a global basis for its sustainability claims.

From 2025 onwards, the strategic geographic focus for its hydrogen ambitions has sharpened considerably, pointing squarely at the Mediterranean and Black Sea regions. The partnership with Greece’s DEPA and Italy’s Edison via the IGI Poseidon JV is explicitly aimed at developing Europe’s hydrogen backbone. This is complemented by the Sakarya offshore gas project in the Black Sea, which, although for natural gas, establishes Tenaris as a key supplier for complex, deep-water energy projects in this critical region. This geographic consolidation suggests Tenaris is positioning itself to capture a significant share of the high-value offshore energy projects emerging in Southern and Eastern Europe, which are central to the continent’s energy security and transition plans.

Technology Maturity: From Material Qualification to Systems Integration

The maturation of Tenaris’s hydrogen technology strategy is evident in its shift from component-level validation to system-level application. In the 2021–2024 period, the focus was on proving the core technology. The 2022 qualification of its line pipe for hydrogen transport was a critical milestone, moving the technology from the lab to a state of commercial readiness. This was supported by demonstration activities like the green hydrogen fuel trial at the Dalmine plant, which explored hydrogen’s role in the manufacturing process itself. These steps were fundamental, answering the question: “Can our product work with hydrogen?”

The period from 2025 to today marks a move toward integration and deployment readiness. The key signal is the evolution of the IGI Poseidon partnership to address “offshore hydrogen readiness.” This is no longer about whether a pipe can contain hydrogen, but how to design, deploy, and operate a complete pipeline system in an ultra-deep offshore environment. This represents a significant step up in complexity, moving from material science to systems engineering. Concurrently, the execution of the Sakarya offshore gas project serves as a full-scale commercial demonstration of the company’s logistical and technological capabilities in laying deep-water pipelines. While the transported molecule is different, the underlying technology of manufacturing, coating, and installing large-diameter offshore pipes is commercially mature and directly transferable, de-risking future hydrogen projects.

Forward-Looking Insights: The Path to Commercial Deployment

The data from 2025 clearly signals that Tenaris is past the exploratory phase and is now executing a deliberate strategy to become an indispensable partner in the offshore hydrogen value chain. The immediate future will be defined by the translation of “readiness” into concrete projects. The most critical signal to watch is the next evolution of the IGI Poseidon partnership. An announcement of a FEED study or a specific pilot pipeline project would represent the definitive move from planning to commercial development.

Furthermore, the successful delivery of the Sakarya gas pipeline provides a powerful template. Market actors should watch for Tenaris to leverage this success story to de-risk proposals for similar offshore hydrogen projects. The company’s strategic narrative is gaining traction: its internal decarbonization through over $400 million in renewable investments provides the ESG credentials, while its offshore project execution provides the technical proof. The final piece of the puzzle, and the key signal for the year ahead, will be securing a supply agreement for a major pipeline that connects a green hydrogen production hub—likely an offshore wind farm—to demand centers. This would validate its entire strategy and solidify its position as a leader in the infrastructure of the energy transition.
