FerraVolt AB and Höganäs AB enter co-development partnership for fossil-free ironmaking
FerraVolt AB and Höganäs AB have entered into a co-development agreement to jointly advance a process for fossil-free iron production. For Höganäs, the initiative supports the transition toward fossil-free raw materials and energy carriers by 2035 and is directly linked to core production requirements. Powder metallurgy depends on consistent, high-quality iron input, and future green feedstocks must meet strict metallurgical specifications as well as economic viability. For FerraVolt, the collaboration advances the development of modular, hydrogen-based ironmaking technology designed for a decarbonised steel industry and energy system. The collaboration focuses on developing a flexible ironmaking concept designed to operate with variable renewable electricity. The process combines electrical heating with hydrogen-based reduction in a rotary kiln configuration. The work will cover process development, pilot validation, and industrial integration pathways for fossil-free sponge iron prod

Members of FerraVolt team secure funding for business development of hydrogen rotary kiln in India
FerraVolt team members are part of a successful consortium that was awarded funding under the Leadership Group for Industry Transition (LeadIT) Industry Transition Partnership (ITP) funding call. The consortium, made up of both Swedish and Indian organisations, including Metsol AB, Höganäs AB, Höganäs India, Aarti Steel and the Indian Insitiute of Technology (IIT) Bhubaneswar, will work together to conduct a feasibility study for a pilot plant based on the hydrogen rotary kiln. FerraVolt team members will play a pivotal role in the design and delivery of this project, representing a vital step in further developing the hydrogen rotary kiln ahead of a large-scale pilot.

FerraVolt team co-author report on rotary kilns in India
In collaboration with Delhi-based research institute, The Energy and Resources Institute (TERI), members of the FerraVolt team co-authored a brief report on the potential role of hydrogen rotary kilns in decarbonising the Indian iron and steel sector. In this report, the authors set out the main challenges faced by the Indian iron and steel sector in decarbonising their production, the leading low emission ironmaking options that are currently in development around the world, and the potential attributes of the hydrogen rotary kiln that would make it suitable for this market. Drawing on initial outcomes from international R&D projects and expert insights, the report highlights key benefits of the hydrogen rotary kiln, including low capital investment, feedstock flexibility, lower reaction temperatures, and increased metallization rates. The paper concludes with recommendations to support the commercialization of this technology, accelerating the decarbonization of India’s steel sector.
