Next-Generation Emission Control

AI-driven

to reduce NOx

We develop advanced emission control systems to accelerate environmental sustainability.

The Challenge & Our Answer

A breakthrough solution
to meet environmental regulations

Strict environmental regulations generate significant pressure on natural gas or biogas-fuelled stationary power generation plants to reduce NOx emissions.

DENOx represents a disruptive alternative for the traditionally used Selective Catalytic Reduction systems using urea (AdBlue), associated with high operating expenditures, installation complexity, and maintenance problems.

DeNOx is a non-urea, hydrogen-based NOx reduction technology, with AI-driven control mechanisms. Our system enables efficient emission reduction without external reagents.

Technological Innovation

Rethinking control with machine learning

DENOx system – A multidisciplinary technological progress: the integration of process chemistry and real-time AI-supported control improves adsorption cycles, regeneration efficiency, and overall system performance.

Our patented DeNOx solution is the first system to radically rethink control opportunities using AI and IoT, applying a Lean NOx Trap for stationary applications.

The system integrates a dual-stage architecture combining an adsorber, an on-board reformer, and an AI-driven control system using advanced pre- and post-NOx sensors. DENOx eliminates urea logistics, reduces catalyst poisoning risk, and lowers operating costs.
