SaltX Technology and Holcim have successfully produced Portland-quality cement clinker using a fully electrified process, potentially paving the way for greener cement manufacturing at scale.
SaltX Technology and Holcim say they have repeatedly produced Portland-quality cement clinker through a fully electrified process, a development that could point to a lower-carbon route for one of the world’s hardest-to-abate industries.
According to the companies, Holcim supplied raw meal that was first calcined at SaltX’s research centre in Hofors, Sweden, before being sintered in SaltX’s newly developed Electric Clinker Reactor. The process replaces the conventional fossil-fuelled rotary kiln and, in the companies’ telling, proves that both major thermal stages in clinker production can be electrified at scale.
That matters because sintering is typically the most energy-intensive and technically demanding step in cement manufacturing. SaltX says its approach combines a more compact reactor design with electrified heat delivery, building on earlier validation of its calcination technology. Holcim has also backed the partnership financially, having invested in SaltX as part of a broader push to develop industrial decarbonisation technologies and examine the potential for all-electric cement production.
The companies describe the latest result as an important milestone on the way to a pilot plant, while industry coverage from S&P Global and CemNet has framed the achievement as a meaningful proof of concept for fossil-free clinker. Holcim’s MAQER Ventures unit said the output met Portland-quality standards, underlining that the material was not merely experimental but consistent with established industrial requirements.
For the cement sector, the significance is less about one laboratory-style success than about whether the process can be scaled reliably, economically and with access to low-carbon power. SaltX and Holcim have said further updates will follow as their joint development programme advances, with the next phase likely to determine whether electrified clinker can move from demonstration to deployment.

This achievement demonstrates a potential pathway to decarbonize cement production, a significant source of greenhouse gas emissions. The calcination process was performed at SaltX’s test and research center in Hofors, Sweden, followed by processing in SaltX’s Electric Clinker Reactor. The sintering stage, which requires higher temperatures, was also fully electrified, confirming the viability of a fully electrified cement production process.

Their Electric Arc Calciner (EAC) enables direct, controlled heating and integrated COâ‚‚ separation, concentrating emissions into a clean stream ready for capture or utilization. SaltX is developing two post-calcination solutions: the Electric Clinker Reactor for a fully fossil-free process and a hybrid route combining the EAC with a traditional rotary kiln for rapid emission cuts using existing infrastructure. Collaborations with industrial leaders like ABB, thyssenkrupp Polysius, and Holcim are scaling these concepts into full-scale industrial applications.
