Gravit Hy Green Hydrogen, €2.2 B Project De-risking, Danieli Contract, and 4 Key Partnerships (2024 to 2026)

Green Iron Projects, Gravit Hy’s Value Chain Integration and Commercial Scaling

Large-scale green iron projects are transitioning from concept to commercial reality by assembling end-to-end industrial consortia that de-risk the entire value chain, from raw material supply to technology deployment and product offtake. The progression of the Gravit Hy project in France demonstrates a clear shift from strategic planning to concrete execution, serving as a model for capital-intensive industrial decarbonization.

Shift from Consortium Formation to Execution

The period between 2021 and 2024 was characterized by the formation of the initial industrial consortium, bringing together key partners like EIT Inno Energy, Engie, and Plug Power to define the project’s scope and strategic objectives. In contrast, the period from 2025 to 2026 marks a decisive move into execution, evidenced by a series of critical commercial milestones. This includes filing for the necessary permits in July 2026, selecting engineering firm Hatch to deliver the Front-End Engineering Design (FEED) in April 2026, and, most significantly, contracting with plant-builder Danieli in August 2026 to supply the core direct reduced iron (DRI) plant. These actions transform the project from a plan into a tangible development with a defined technological and commercial pathway.

Enabling the Market with a Merchant HBI Model

Gravit Hy‘s strategy to operate as a merchant supplier of Hot Briquetted Iron (HBI) addresses a critical bottleneck for the wider steel industry. This model allows existing Electric Arc Furnace (EAF) operators, who often lack integrated ironmaking capabilities, to access low-carbon feedstock and reduce the carbon intensity of their final products. The cooperation agreement signed with Italian steel processor Marcegaglia in February 2026 is a key validation of this approach. It signals clear market demand for a standalone green iron product and creates a foundational pathway for the offtake agreements necessary to secure the project’s final investment decision.

€2.2 B Total Capex, Gravit Hy’s Phased Funding Strategy for Green Iron

Gravit Hy‘s funding strategy mitigates financial risk by securing capital in distinct, targeted phases. This approach uses initial, smaller fundraising rounds to complete the critical engineering, design, and permitting work required to de-risk the project sufficiently to unlock the full €2.2 billion in project financing needed for construction.

Securing Pre-FID Development Capital

The €60 million fundraising round announced in March 2025 was not for construction but was specifically allocated to advance the project to a bankable state. This capital funds essential pre-development activities, including the advanced engineering studies being conducted by Hatch and the complex environmental and construction permitting process. By using this initial funding to resolve key technical and regulatory uncertainties, the consortium makes the project more attractive to the large-scale debt and equity financiers required for the next phase. This approach is becoming standard for capital-intensive energy projects, especially where the high cost of inputs like green hydrogen presents a commercial risk.

Attracting Strategic Corporate Investment

The planned investment from Ecolab, announced in June 2026 as part of the “Choose France” summit, shows the project’s ability to attract strategic corporate investors beyond its founding members. This type of investment serves as a powerful validation of the project’s commercial viability and its alignment with the broader industrial push for sustainable supply chains. Unlike traditional project finance, corporate investments often come with strategic benefits, including potential technical collaboration or offtake arrangements, further strengthening the project’s foundation.

Gravit Hy’s 4 Key Alliances De-risking its French Green Iron Project (2024 to 2026)

Gravit Hy has systematically mitigated technology, supply, and market risk by forging a web of strategic partnerships across the entire project lifecycle. This approach secures proven technology, reliable engineering, raw material supply, and market offtake before committing to major construction, creating a highly de-risked investment case.

Technology and Engineering Validation

The selection of key suppliers in 2026 was a critical de-risking move. Contracting with Danieli in August 2026 for its hydrogen-ready Energiron DRI technology ensures the project uses a mature, commercially available solution rather than bearing the risk of scaling a novel process. This is complemented by the appointment of Hatch in April 2026 to manage the FEED, bringing world-class engineering discipline to the project’s design phase. Together, these partnerships provide a strong foundation of technical and executional certainty.

Securing the Value Chain Ends

The consortium has secured both ends of its value chain through strategic alliances. The November 2024 partnership with mining giant Rio Tinto is designed to address upstream risk by exploring a stable supply of high-grade iron ore, the essential raw material for the DRI process. Concurrently, the February 2026 cooperation agreement with steelmaker Marcegaglia addresses downstream market risk by establishing a clear path to offtake for the final HBI product. This end-to-end approach, from mine to market, is crucial for projects of this scale, such as the massive NEOM green hydrogen facility.

France vs. Sweden, Gravit Hy Establishes a Mediterranean Green Steel Hub

Gravit Hy‘s decision to build its flagship plant in Fos-sur-Mer establishes a major southern European hub for green iron production. This move creates a strategic counterweight to prominent Nordic projects and capitalizes on France’s unique low-carbon energy profile and established coastal industrial infrastructure.

Leveraging France’s Low-Carbon Grid

A key strategic advantage for the Gravit Hy project is its plan to power a large, 720 MW on-site electrolyzer complex using France’s nuclear-dominated electricity grid. This allows for the production of low-carbon hydrogen at a scale and with a consistency that is challenging to achieve in regions heavily reliant on intermittent renewable energy sources. By leveraging this baseload, low-carbon power, the project can minimize the “green premium” on its hydrogen and, consequently, its final HBI product.

Fos-sur-Mer’s Logistical Advantage

The plant’s location in the industrial port zone of Fos-sur-Mer provides critical logistical superiority. The deep-water port access facilitates the efficient import of iron ore from global suppliers and enables cost-effective shipment of the finished HBI to steelmakers across the Mediterranean and Northern Europe, including partner Marcegaglia in Italy. This strategic positioning contrasts with more remote inland projects, such as H 2 Green Steel in Boden, Sweden, which have different logistical considerations. The emergence of multiple hubs, including the Stegra Project, signals a healthy regional diversification in Europe’s growing green steel industry.

Commercial Scale DRI, Gravit Hy Adopts Proven Energiron Technology

Gravit Hy is accelerating its path to commercial operation by acting as a technology integrator rather than an inventor. The consortium’s selection of Danieli‘s proven Energiron direct reduction process, which is already designed to operate with high concentrations of hydrogen, is a deliberate strategy to minimize technology risk and focus on execution at scale.

Danieli’s “Hydrogen-Ready” Solution

The choice of the Energiron technology is a cornerstone of the project’s de-risking strategy. The plant is engineered to operate on a flexible blend of natural gas and hydrogen, with the ability to transition to 100% low-carbon hydrogen as supply becomes available. This flexibility mitigates the risk of being entirely dependent on the immediate, full-scale availability of green hydrogen at startup. Furthermore, the process is designed to produce a premium product: HBI with a metallization rate of up to 96%, making it an ideal, high-purity feedstock for EAF steelmakers.

Integrating Electrolysis at Scale

While the core DRI process is mature, a significant technological and integration challenge lies in the deployment of the on-site hydrogen production facility. The project includes a planned 720 MW electrolyzer complex, one of the largest in Europe. Although core PEM electrolysis technology from providers like consortium partner Plug Power is advancing rapidly, integrating it at this scale to ensure a reliable, 24/7 supply of hydrogen for a heavy industrial process remains a key execution challenge that the project must solve.

Gravit Hy’s 2027 FID, Offtake Agreements are the Critical Path

To reach its targeted Final Investment Decision (FID) by 2027, Gravit Hy must successfully convert its existing cooperation agreements into binding, long-term offtake contracts. The bankability of the €2.2 billion project ultimately depends on its ability to demonstrate secured, predictable revenue streams to potential financiers.

• If Gravit Hy secures binding offtake agreements for a significant portion of its 2 million tonne annual capacity within the next 12 to 18 months, watch for the announcement of a lead project finance banking consortium. This would be a powerful signal that the project has met the de-risking thresholds required by major lenders.
• This could mean that the project is firmly on track for its 2030 operational start date, validating the merchant HBI model as a viable and scalable pathway for industrial decarbonization in Europe.
• However, if these offtake agreements are delayed or are priced without a sufficient “green premium” to cover the higher cost of production, watch for potential adjustments to the project timeline or an increased reliance on public subsidies to close the economic viability gap. The outcome is critical, as several major green steel projects globally have recently faced delays or cancellations.
• This could mean that while the technology is ready, the market is not yet prepared to fully absorb the cost of green iron feedstock, creating significant headwinds for the next wave of capital-intensive decarbonization projects waiting for a green light.
