The steel industry currently accounts for approximately 8% of global carbon emissions. With each tonne of steel production releasing an average of 1.63 tonnes of CO₂, there is a pressing need for more sustainable solutions. The open research Hydra project aims to reduce emissions to mere kilograms of CO₂ per tonne of steel and will make this world-changing technology available to the industry on the way to net zero.
Located at RINA’s Centro Sviluppo Materiali (CSM) in Castel Romano, Italy, and funded through an €88-million European Commission NextGenerationEU investment, the six-year Hydra initiative is part of the IPCEI (Important Projects of Common European Interest) programme and will involve a dedicated team of 120 people.
The project’s innovation lies in its extensive use of hydrogen throughout the steel production process. By 2025, the facility is set to feature a direct iron ore reduction (DRI) tower, which will use hydrogen as its primary reducing agent, as well as an electric furnace and a reheating furnace.
Through a testing and qualification hub, the project will also characterise the materials, equipment and internal infrastructure required, including transportation and storage, by steel producers to transition to 100% hydrogen-fuelled steel production.
Ugo Salerno, Chairman and CEO of RINA, reflected on the project’s potential: “The Hydra project underscores our commitment to sustainable innovation. While it offers a technological shift, its unique open research nature ensures that its benefits can be shared across the steel industry. Our aim isn’t just to benefit one player but to contribute to the industry’s collective move towards more eco-friendly processes. This is why the Hydra project has been supported since its inception by leading European steel producers, plant suppliers, utilities and major stakeholders in the sector.”
Furthermore, thanks to its extensive experience in hydrogen-based decarbonisation technologies, including the world’s first test of a 30% gas-hydrogen blend in steel forging, RINA plans to introduce a training centre as part of the Hydra project, focusing on the intricacies of their application. This centre is expected to serve as an international hub, fostering collaboration and research among stakeholders in the steel and energy sectors.
