SaltX Technology has developed an electrified solution for the industrial process of calcination. Calcination means that material is modified by heating to very high temperatures to change its properties-a method used, among other things, to manufacture lime and cement. The company has now been granted a patent for its electric calcination technology in Sweden.

The technical solution, EAC (Electric Arc Calciner), replaces fossil fuels with renewable electricity and isolates the carbon dioxide released from the material during heating. The innovation provides an entirely emission-free manufacturing process. The patent granted in Sweden covers several parameters, such as the cyclone's design, the plasma generator's properties, the material's rotation, and the carbon dioxide's separation.

In addition to eliminating carbon dioxide emissions from, for example, the production of quicklime, the technology provides many other benefits. Lars Croon, Head of Innovation at SaltX. The areas of use of the now patent-protected electric calcination technology include, in addition to the lime and cement industry, materials such as magnesium, lithium, and carbonate minerals.

The EAC (Electric Arc Calciner) technology also forms the basis for SaltX's other business area, energy storage, where the technology is used as a charging reactor of energy storage materials.
