Salt X and ABB Strengthen Collaboration to Electrify Emission-Intensive Industries

ABB and Sweden-based greentech company Salt X have signed an agreement to enable the further development of technologies in the Electric Arc Calcination (EAC) process. ABB will also become a minority shareholder in Salt X.

The two companies are known for their expertise in electrifying emission-intensive industries, including in the production of cement and quicklime, highly sought after materials in modern construction and process industries. Today, manufacturers are dependent on fossil fuels for high-temperature heating, up to 900 degrees Celsius, and have no realistic alternative.

Under the new agreement, Salt X will further develop its innovative Electric Arc Calciner (EAC), a technology that makes it possible to reach several thousand degrees Celsius. The electric plasma solution reinvents industrial calcination – the process used to heat materials to high temperatures – and replaces fossil-driven heating with renewable electricity while capturing the CO₂ emissions released. ABB will contribute with control and electrical systems for the EAC, creating a strong joint offering to the market. The collaboration aims to accelerate the commercialization of Salt X's electrification and carbon separation technology.
