The Swedish steel manufacturer SSAB and the German defense and supply company Rheinmetall have signed a letter of intent for the supply of fossil-free steel.
According to a statement from SSAB, this is a milestone as Rheinmetall is the first defense equipment manufacturer to use decarbonized steel in its production. The collaboration will begin with deliveries of SSAB Zero. The quantities will increase over time, although the steel manufacturer has not provided any specific figures. Future deliveries will also include SSAB Fossil-free steel, which is produced using the Hybrit technology.
SSAB Zero is the first commercial, decarbonized steel. By using recycled steel and fossil-free energy, there are virtually no fossil carbon emissions. In 2021, SSAB produced the world’s first fossil-free steel using Hybrit technology as a proof of concept. This steelmaking process uses hydrogen-reduced sponge iron and replaces the main source of CO₂ emissions with water as a by-product instead of CO₂. Since then, several pilot deliveries have been made to partners in various industries.
