H-ACERO 2 project, which continues with the objectives of H-ACERO 1, represents a decisive step towards transforming the steel industry into a NetZero sector, through the intensive use of green hydrogen (H₂) and oxygen (O₂) in its production processes. In this way, the aim is to replace fossil fuels with clean energy sources, reducing greenhouse emissions and promoting decarbonization within the steel industry.
In this ambitious project, which Nippon Gases joined from the start, efforts have focused on advancing the field by developing hydrogen-adapted electric arc furnace prototypes and exploring the use of green DRI as a sustainable raw material. In addition, key technological challenges have been addressed, such as the development of innovative refractory materials, the adaptation of burners to operate with H₂ and O₂, and the industrial validation of the use of hydrogen in critical stages of the process.
H-ACERO2 is fully aligned with the Basque Government’s strategy and the Horizon Europe plan, embracing the goal of achieving climate neutrality in the European Union by 2050. With a strategic timeline, this project represents a pioneering collective effort in Europe and serves as a roadmap to achieve the objectives set. Through this alliance, the group reaffirms its commitment to decarbonization and the adoption of best practices in the sector, anticipating future regulatory requirements, reducing its carbon footprint and strengthening its competitiveness in an increasingly sustainability-driven market.
Scope and objectives
With the participation of 12 leading industrial companies and 5 technology centers, the project covers all key stages of the steelmaking process — from melting in electric arc furnaces (EAF) to the preheating of ladles and tundishes, reheating furnaces, and the oxy-fuel cutting process. It aims to drive the comprehensive decarbonization of the Basque steel sector through the development and validation of innovative industrial technologies, including hydrogen burners, steam-resistant refractories, and furnace prototypes adapted for oxy-fuel combustion. The project also involves a comparative and experimental study of green DRI use, with the goal of reducing emissions associated with raw materials, as well as the generation of technical and scientific knowledge through simulations, industrial-scale testing, and the development of holistic hydrogen assessment tools.
