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 production.
This expands the range of viable deployment models for green iron beyond large, continuously operated installations.

Q&A
What makes the technology unique?
The technology combines hydrogen-based reduction with electrical heating in a modular rotary kiln configuration. This enables a flexible production model that can integrate with renewable energy systems and operate at smaller, distributed scales compared to traditional ironmaking routes.
What stage of development are you in?
The technology has been validated at laboratory level and is now entering a structured pilot development phase through the co-development agreement.
What level of CO₂ reduction do you expect from this process?
The process is designed to eliminate direct CO₂ emissions from ironmaking by using hydrogen as the reductant and electricity as the heat source. The overall footprint will depend on the carbon intensity of the hydrogen and electricity used.
When do you expect this to be commercially viable?
The current focus is on pilot development and validation. Commercial deployment will follow based on technical results, industrial integration, and market conditions.
