FerraVolt re-engineers the rotary kiln to operate with hydrogen as the reductant and electricity as the primary heat source, eliminating fossil combustion from the reduction process. The system provides a controlled, high-temperature environment for producing Direct Reduced Iron (DRI).

Iron ore is continuously fed into a rotating, inclined kiln, while hydrogen flows counter-currently to reduce iron oxides to metallic iron. The process combines electrified heat supply, hydrogen-based reduction, and a modular reactor design into a fossil-free ironmaking route aligned with modern energy systems.
