"Our Mission"

Empowering heavy industries with localized, zero-emission ammonia solutions to feed and power the planet sustainably.

Our technology

A one-step, modular electrolysis stack that produces ammonia from water, air and green electrons. But what makes us different?

No green hydrogen needed
We bypass hydrogen production and storage entirely, straight from air and water to ammonia in one step.
Earth-abundant catalysts
Non-platinum group electrodes made from abundant materials, significantly reducing manufacturing costs and supply chain risk.
Modular and scalable
Decentralised units sit wherever curtailed renewable energy exists, turning a grid management problem into a green ammonia opportunity.

Inside The Nitrolyzer Cell
Meet our Team
Two electrochemistry specialists eager to industrialise novel technology.
CEO · Co-founder
Ash Stott
CTO · Co-founder
Ben Kyffin
Ash's PhD focused on electrochemical degradation, a niche but crucial area for industrialising technology. As senior electrochemist at Ceres Power, he led the cathode degradation team in collaboration with Robert Bosch, de-risking hydrogen fuel-cell performance at scale. That experience taught him that hydrogen has fewer practical use cases than the hype suggests, and that there had to be a better material for climate impact.
Ben brings complementary skills in making systems work at scale. His background spans large-scale synthesis of liquid crystalline materials, modelling pharmaceutical processes, and process development for energy storage devices. At Ceres Power, he focused on scaling up energy materials and applying new electrode materials in commercial environments, turning lab-scale breakthroughs into manufacturable reality.
