CO2 free production of critical raw materials using hydrogen
The context
Hydrogen is less effective in reduction than carbon, making it unsuitable for producing certain strategic metals like:
Silicon

Manganese


This limitation narrows the decarbonization options for these essential industries.



The challenge
A new Critical Raw Materials production pathway where renewable hydrogen is used indirectly to replace fossil carbon
This process captures CO₂ from off-gases, utilizes renewable hydrogen, and repurposes the recovered carbon as a reduction material in metal production, promoting sustainability in the industry.
The goals

Save 33 million tonnes of annual CO2 emissions in 2050

Replace 9 million tonnes of annual coal imports by 15 million Nm3 of H2 in 2050

95% reduction of CO2-emissions from Si and Mn production
