GravitHy selects Danieli for its 2 million tonnes Direct Reduction Plant in Fos-sur-Mer

GravitHy and Danieli Partner to Build One of Europe’s Largest Hydrogen-Based Iron Production Facilities

GravitHy, the future producer of low-carbon iron for the European steel industry, announced the strategic signing of a contract with Danieli for the Direct Reduction Plant (DRP) of its flagship project in Fos-sur-Mer, France.

Under the agreement, Danieli will provide the process plant and the technological design for a state-of-the-art direct reduction plant using Energiron technology, jointly developed by Danieli and Tenova. This plant is designed to produce up to 2 million tonnes per year of high-quality hot briquetted iron (HBI), a premium form of Direct Reduced Iron (DRI), with easy storage and logistic for use in low-carbon electric steelmaking. The facility is being designed to operate with 100% hydrogen as reducing gas, supporting GravitHy’s ambition to deliver low-carbon iron to steelmakers across Europe.

This contract represents a major milestone in the GravitHy project, securing one of the plant’s core process units. This unique cooperation for a DRI plant in Europe sets a high standard for the European green steel industry. It will also enable the progress of GravitHy’s FEED (Front End Engineering Design) studies which is a key piece to derisk the project before Final Investment Decision (FID) planned for 2027.

A technological cornerstone of GravitHy’s industrial plant

The Direct Reduction Plant will form the heart of GravitHy’s industrial process, transforming iron ore into Direct Reduced Iron using hydrogen instead of conventional coal-based reduction methods. Designed around hydrogen-based ironmaking, the DRP will play a critical role in reducing carbon emissions associated with steel production, by -90% on the overall value chain compared to traditional blast furnace steelmaking, while supporting the emergence of a competitive, resilient and sovereign European low-carbon steel value chain.

Maximizing value across the entire production chain

Beyond its standalone performance, the Energiron technology has been selected for its ability to generate synergies across the broader GravitHy industrial ecosystem. The process design enables the optimization of energy use, utilities management and plant-wide operational efficiency, while ensuring seamless integration with hydrogen production, water treatment and downstream logistics assets. This holistic approach is intended to deliver operational safety, world-class product quality, operational reliability and competitive low-carbon iron production for European steelmakers.

The plant is designed to produce high-quality HBI suitable for electric steelmaking applications,
combining high metallization rates and optimized carbon content to meet the performance
requirements of modern low-carbon steel production routes.

Strengthening project delivery

The selection of Danieli reflects GravitHy’s commitment to partnering with leading industrial
technology providers capable of delivering on time high-performance, reliable and future-ready
solutions.

Beyond supplying key process equipment, the design of the direct reduction plant will maximize
synergies with other parts of the GravitHy facility, supporting operational efficiency, energy
optimization and the production of world-class low-carbon iron products for European customers. Located in the industrial and port ecosystem of Fos-sur-Mer, the project will contribute to the emergence of a major European hub for low-carbon iron and steel production, supporting industrial sovereignty, competitiveness and decarbonization objectives.
