Tenaris Green Hydrogen Strategy, $280 M Texas Plant, IGI Poseidon Partnership, and 2 Key Project Deliveries (2025)

Tenaris Hydrogen Commercial Strategy, Navigating 2025 Market Cancellations

In 2025, Tenaris S.A. executed an infrastructure-first strategy that insulated it from the significant volatility and project cancellations impacting the broader green hydrogen production market. By focusing on the essential, non-discretionary components required for hydrogen transport and storage, the company solidified its position as a critical enabler of the energy transition, independent of the immediate economic viability of large-scale hydrogen production projects.

Pivoting to Infrastructure Certainty

The company’s strategy avoids direct exposure to the risks of hydrogen production by supplying the fundamental “picks and shovels” of the sector. While many producers faced headwinds in 2025 from rising costs and uncertain offtake agreements, demand for the pipes and vessels to move and store hydrogen remained a prerequisite for any project, whether green, blue, or grey. This approach leverages Tenaris‘s core competency in manufacturing high-specification steel products for the energy industry.

Dual-Use Application De-Risks Demand

Tenaris further de-risked its hydrogen entry by becoming its own customer, initiating trials to use hydrogen in its energy-intensive steelmaking operations. This dual strategy creates a practical testbed for its products and establishes an internal offtake market, providing a valuable hedge against external market development delays. This model mirrors strategies seen with other industrial majors like Total Energies, who leverage captive demand to validate new energy ventures.

$680 M in 2025, Tenaris Capex for Hydrogen-Ready Manufacturing

Tenaris backed its hydrogen strategy with significant capital commitments in 2025, totaling over $680 million across manufacturing capacity expansion and renewable energy development. These investments were strategically allocated to enhance its ability to supply the hydrogen market and to advance its own corporate decarbonization goals, creating a vertically integrated approach to the energy transition.

Tenaris Manufacturing and Energy Investments

The company’s investments targeted both the supply and demand sides of its strategy. A major capital injection into its Texas facility prepares its core business for the hydrogen economy, while its renewable energy projects in Argentina provide the clean power necessary for future green steel and potential green hydrogen production. This positions the company to meet demand driven by policy incentives like the US 45 V tax credit, finalized in January 2025.

Tenaris 2 Key Partnerships for H 2 Transport and Steelmaking (2025)

In 2025, Tenaris established critical partnerships to resolve technical and operational hurdles in the hydrogen value chain. These collaborations focus on two key areas: enabling the transport of hydrogen in challenging offshore environments and proving the viability of hydrogen as a decarbonization fuel in industrial steelmaking.

Tenaris, Snam, and Tenova Steel Trial

The alliance with Snam and Tenova at the Dalmine mill represents a landmark test for the Italian steel industry. By using hydrogen in the steelmaking process, Tenaris not only advances its own decarbonization but also generates crucial operational data on hydrogen’s performance in heavy industry, a sector that companies like Enel are targeting for decarbonization. This initiative provides a real-world use case that validates the demand for hydrogen beyond mobility.

IGI Poseidon Offshore Transport Project

The partnership with IGI Poseidon tackles a future-critical challenge: the safe and efficient transport of hydrogen via subsea pipelines. As offshore wind projects are increasingly coupled with hydrogen production, the ability to move the molecule from sea to shore becomes paramount. This collaboration positions Tenaris to be a key equipment supplier for this emerging market segment, much as oilfield service firms like SLB build infrastructure for new energy systems.

US and Europe, Tenaris Geographic Focus for H 2 Infrastructure

In 2025, Tenaris concentrated its hydrogen activities in regions with robust policy frameworks, industrial demand, and clear infrastructure deficits. Its deployments and investments were strategically placed in the United States, Europe, and the Middle East, targeting first-mover opportunities in markets actively building out hydrogen ecosystems.

Tenaris Deployments in Europe and the Middle East

The company secured landmark projects in both mature and emerging hydrogen markets. Supplying the storage system for Italy’s first highway hydrogen refueling station established a key domestic reference point. Simultaneously, delivering the storage system for Oman’s first green hydrogen station provided an early foothold in a region with ambitious goals to become a major hydrogen exporter, aiming for 1.2 million tonnes of green hydrogen production annually by 2030.

Tenaris Investments in the Americas

In the Americas, Tenaris‘s investments were aligned with long-term strategic goals. The $280 million expansion of its Bay City, Texas, pipe facility is a direct response to anticipated North American demand for hydrogen pipelines, supported by US clean energy policies. In parallel, the $400 million renewable energy investment in Argentina lays the groundwork for decarbonizing its own operations, a strategy also pursued by its oilfield service peers like Weatherford.

Tenaris Technology at Commercial Scale for Pipes and Storage in 2025

By 2025, Tenaris moved its primary hydrogen technologies from development to commercial reality, validating its product portfolio through real-world deployments. The company demonstrated that its specialized seamless pipes and high-pressure storage systems are ready to meet the technical demands of the nascent hydrogen economy, a transition that competing suppliers like NOV have also navigated with varying focus.

THera® System: From Concept to Commercial

The THera® hydrogen storage system was a key focus, successfully transitioning to a commercial product in 2025. Prior development and qualification efforts culminated in deliveries for two flagship hydrogen refueling stations in Italy and Oman. These projects served as crucial proof points, demonstrating the system’s capability to safely store hydrogen at the high pressures required for mobility applications.

Validating Hydrogen-Ready Steel Pipes

While the qualification of steel pipes for 100% hydrogen service is an ongoing process across the industry, Tenaris‘s $280 million investment in its Texas plant signals confidence in its technology. The decision to expand capacity was predicated on meeting verified customer demand for pipes that can handle hydrogen, indicating that its materials science and testing programs have reached a mature stage. The Dalmine steelmaking trial further contributes to this by providing data on hydrogen’s effects on industrial materials.

SWOT Analysis, Tenaris Hydrogen Strategy Execution Risks in 2025

The strategic analysis of Tenaris reveals a company effectively leveraging its established manufacturing expertise and market position to address the emerging hydrogen economy. Its primary strength lies in its “picks and shovels” approach, while its main weakness is a dependency on the pace of broader infrastructure build-out, which is outside its direct control.

Tenaris Scenario: Watch for H 2 Pipeline Project Final Decisions

The primary signal for Tenaris‘s future growth trajectory is the progression of large-scale hydrogen pipeline projects from proposal to Final Investment Decision (FID). The company’s strategy is positioned to capitalize on the construction of major transport networks, such as the European Hydrogen Backbone, and its order book will be a direct reflection of their advancement.

Signals for Tenaris’s Hydrogen Growth

If FIDs for major pipeline networks are announced, watch for a significant increase in Tenaris‘s backlog for high-specification pipes. This would validate its $280 million Texas investment and likely trigger further capacity expansions. Conversely, if these large projects remain stalled due to policy or economic uncertainty, as seen with some projects by Woodside Energy, expect Tenaris‘s growth in hydrogen to be more modest, driven by the smaller but steady market for industrial applications and vehicle refueling stations. The nature of its future partnerships, whether with midstream operators or industrial consumers like those targeted by Iberdrola, will be a key indicator of the market’s direction.
