SaltX Technology is advancing its Electric Arc Calciner (EAC) platform, a high-temperature electrification technology engineered to decarbonize industrial processes through plasma-based heating and process-integrated carbon capture. The solution targets energy-intensive sectors such as cement and quicklime production, where conventional calcination relies on fossil fuel combustion to achieve temperatures exceeding 900°C.
The Electric Arc Calciner replaces combustion-driven heat generation with electric arc plasma, enabling direct conversion of electrical energy into high-temperature thermal energy. This approach provides precise and controllable heat delivery while eliminating combustion-related emissions. By decoupling thermal processing from fossil fuels, the system enables industrial operations to transition toward renewable electricity-powered production without compromising process efficiency or throughput.
A defining characteristic of the EAC platform is its intrinsic carbon capture capability. In conventional calcination processes, CO2 emissions arise both from fuel combustion and the decomposition of carbonate materials such as limestone. By removing combustion from the process, the EAC isolates process-derived CO2 into a high-purity, concentrated stream, suitable for carbon capture, utilization, or storage. This integrated approach reduces the energy overhead and system complexity typically associated with post-combustion capture technologies.
The Electric Arc Calciner is designed for continuous industrial operation and scalability. The system incorporates high-power electrical input stages to sustain stable arc formation, supported by advanced control systems that regulate arc dynamics, heat distribution, and process stability under varying operating conditions. The reactor architecture enables efficient material throughput while withstanding extreme temperature and chemically aggressive environments, making it suitable for deployment within existing industrial production lines.
The technology is being progressed through initiatives such as Zero Emission Quicklime (ZEQL), demonstrating the feasibility of fully electrified lime production with integrated CO2 separation. This approach enables near-zero direct emissions while maintaining consistent product quality, offering a scalable pathway toward decarbonizing cement and lime manufacturing.
Electrification of calcination at this scale introduces challenges related to power delivery, grid integration, and load management, given the high and continuous energy demand. The EAC platform is designed to operate with high-capacity electrical infrastructure and can be aligned with renewable energy sources through flexible process control strategies. This positions the technology within the broader transition toward electrified, low-emission industrial energy systems.
By combining plasma-based heating with integrated carbon capture, SaltX is establishing a shift from fuel-based thermal processing to electricity-driven industrial heat generation, addressing a critical segment of global industrial emissions.
