Catalytic reduction of CO2 gas to solid carbon - towards emission-free steelmaking

CatCO2

The steel industry faces significant challenges due to its reliance on fossil fuels and carbon-based materials, which are major sources of CO2 emissions. Achieving negative emissions and decarbonizing steel production is critical to meet global climate targets. CO2 valorization into solid products that could be used as a feedstock for production of useful engineering materials and components is expected to be key in achieving these negative emissions. This project, led by Polestar Perfomance AB in collaboration with KTH and SSAB, will propose and demonstrate a process for converting CO2 into solid carbon using hydrogen and a metal catalyst.

The potential application of resulting solid carbon in steelmaking will be assessed in collaboration with consortium partners. This approach not only offers the potential for permanent carbon sequestration but also opens the door to creating circular carbon materials that can be reintegrated into industrial processes, thereby enhancing sustainability. SSAB and Polestar, key partners in this project, are already actively engaged in the Mission 0 House initiative (partly financed by Vinnova), where they have recognized the importance of this research area for achieving the elimination of greenhouse gas emissions in steelmaking and beyond. Their participation in this project indicates their commitment to pioneering solutions that will enable the transition to a truly fossil-free steel industry.
