ABOUT

Decarbonisation that pays for itself.

We are Natrium Redox, a UK deep-tech company transforming how the world makes steel and cement. The Natrium Redox suite of technologies was invented by our UK-based Chief Scientific Officer, and delivers high-purity metals, minerals and chemicals economically, with zero process CO₂. The science is settled. Our work now is industrial execution.

Our founding team has built and operated complex industrial projects in some of the world's most challenging environments, and we are leveraging partner relationships to keep the company lean while we do it.

Our belief
A new future of low embodied-carbon construction is available to us today.
Marcus Cavalier, Chief Scientific Officer

The goal is not decarbonisation at any cost. It is decarbonisation that happens because the cleaner route is also the cheaper one. Our process is cost-competitive with traditional methods, so adoption does not depend on carbon pricing, subsidies, or customers willing to pay a premium.
