The collaboration involves the joint development and validation of technology to electrify the cement manufacturing process and enable fossil-free production of clinker, the main component in cement. The technology platform combines electrified calcination (EAC) with electrified sintering (a new development). The parties have created a shared technical and commercial roadmap, aiming first to demonstrate the technology at pilot scale and then to facilitate industrial-scale up.

Lina Jorheden, CEO of SaltX Technology:
"The strengthened partnership with Holcim confirms the potential of our technology and marks a key step in developing electrified clinker production. By combining our technology with Holcim's industrial expertise, we can jointly further develop and industrialize solutions for large-scale electrified cement manufacturing."

When SaltX and Holcim formed their strategic partnership, Holcim also invested in SaltX and is now among its major shareholders. The investment demonstrates Holcim's strong confidence in the technology and its industrial potential.

Ram Muthu, Head of Operational Excellence, Holcim:
"SaltX's groundbreaking technology gives us an additional lever to decarbonize the cement manufacturing process. By deepening our collaboration with SaltX, we intend to enhance our ability to produce near-zero cement at scale to meet customer demand as the leading partner for sustainable construction."

Two development tracks for electrified cement manufacturing

Within the framework of the collaboration between SaltX and Holcim, two technical development tracks are being pursued.

The first development track focuses on electrified calcination, in which cement raw meal is heated with plasma burners in SaltX's Electric Arc Calciner (EAC) to produce calcined material. Calcination is one of the most energy-intensive steps in clinker production and the main source of CO₂ emissions. Following successful tests with plasma technology by SaltX and Holcim, the two companies plan to conduct large-scale technology and materials testing at the Electric Calcination Research Center (ECRC) in Hofors during 2026.

The second development track aims to develop a fully electrified clinker manufacturing process in which electrified calcination is combined with innovative electric sintering to produce clinker without fossil fuels. The work involves ongoing technology development as well as a comprehensive material testing program during the year, focusing on validating and optimizing clinker production before the next development phase.

The two technical development tracks can be implemented both separately and together in future cement plants. This provides flexibility for deployment in existing facilities as well as in new installations.
