SaltX Technology and Holcim make a significant stride towards fully electric cement manufacturing, producing Portland-quality clinker without fossil fuels in a fully electrified process for the first time.
SaltX Technology and Holcim say they have taken a significant step towards all-electric cement production after repeatedly making Portland-quality clinker in a fully electrified process.
According to the companies, Holcim supplied raw meal that was first calcined at SaltX’s test and research centre in Hofors, Sweden, before being processed in SaltX’s newly developed Electric Clinker Reactor. The work replaces the conventional fossil fuel kiln route, with the firms saying the clinker met established industrial quality requirements.
The development matters because clinker production is the most carbon-intensive stage of cement manufacturing and the sintering step demands the highest temperatures. SaltX and Holcim are positioning electrification of both calcination and sintering as the route to removing direct fossil fuel use from the process, while also pointing to a more compact plant design and greater operational flexibility than a traditional rotary kiln set-up.
SaltX chief executive Lina Jorheden said the result showed that a fully electrified cement process can be implemented in an industrial environment. Holcim’s Bengt Steinbrecher, head of MAQER Ventures, said the outcome provided strong validation of SaltX’s technology and an important milestone on the scale-up path.
The latest trial builds on an earlier joint development agreement between the companies focused on electrified clinker production. Holcim has also said it has invested in SaltX’s plasma technology as part of a wider decarbonisation push, with the longer-term ambition of supporting the first all-electric cement plant.
For industrial decarbonisation professionals, the significance is clear: this is no longer just about lab-scale electrification, but about proving that the hardest part of cement making can be done with electricity alone. The companies said the result brings them closer to a planned pilot plant, with further updates expected as the project advances.
