Green-Gas Real-Time Impurity Detection System.
The first real‑time gas‑quality monitoring solution built for the net‑zero transition.





Continuous, real‑time detection of key impurities.
We address a critical gap in real‑time, continuous gas‑quality monitoring for hydrogen, biomethane, and CCUS streams as the UK transitions toward net‑zero. Green GRIDS enables continuous, real‑time detection of key impurities, including ammonia, hydrogen sulfide, and water to support net-zero gas‑quality assurance.
Current gas‑analysis technologies typically provide intermittent, time‑averaged, or batch‑based measurements. This means they cannot detect rapid, transient impurity events that can occur during production, blending, transportation, or storage.
Solving The Problem
Safer, more efficient, and more reliable operation of emerging low‑carbon gas infrastructure.
Terahertz-based System
We provide the first prototype terahertz‑based system capable of real‑time, continuous, multi‑species impurity detection across hydrogen, biomethane, and CCUS gas streams.

Operator Visibility
This give operators immediate visibility of contaminants that were previously hard or slow to detect, and enables safer, more efficient, and more reliable operations during the transition to net zero.
