We use salt and water to produce high-purity iron and manganese metals, a range of critical minerals and lime, all at lower cost and energy than any process in the market, with zero process CO₂.
We have used a modern understanding of physics and chemistry to reimagine how these globally significant products are produced. Every part of what we do has been proven at industrial scale for decades. It is how we efficiently combine the processes that delivers the value, and industrial decarbonisation.
Reducing emissions from steel and cement has so far depended on something outside the process to make it work, whether a subsidy, a carbon price, or a customer willing to pay more for the same material. The Natrium Redox™ process sits below the cost-curve of comparative technologies without any of those benefits.
High-purity iron and manganese can be delivered to existing plants today or taken to higher value battery supply chains.
The reactions require no energy input. They generate energy. We control these reactions with heat transfer away to dry products and reduce input energy needs elsewhere. That is what puts the process below the cost-curve of comparative technologies without a carbon premium.
Zero process CO₂. Where CO₂ is produced in the plant, the CO₂ is contained and leaves as sodium carbonate and is sold at profit.
Residues held in storage as liabilities become feedstock. Iron, manganese, alumina, titania and rare earths are recovered from material already mined and discarded.
The process works with raw materials already being mined, at a cost that does not depend on a carbon price. We license to producers who have the sites, the feedstock and the customers.
