Product Benefits
Key advantages of continuous hydrogen monitoring in methanation systems.
Correct H₂ Delivery
Keep the right H₂/CO₂ ratio to maximise conversion and methane yield.
Protect the Catalyst
Detect conditions that can poison or damage catalyst beds and spot hotspots early.
Safety & Control
Detect leaks or dangerous H₂ pockets so you can alarm, isolate, or shut down automatically.
Where to Place Sensors
Strategic sensor placement for complete reactor coverage.
- H₂ feed lines — upstream and downstream of injectors
- Membrane contactors / spargers — at the gas–liquid interface to confirm transfer
- Reactor inlet & outlet — verify feed composition and product gas
- Recycle loops — find imbalances or carryover H₂
- Catalyst bed vicinity — distributed sensors to detect channeling or local failures
- Pressure-relief points & vents — detect vented hydrogen and unsafe releases
What Monitoring Delivers
Automatic safety actions (isolate, vent, cut feed), real-time stoichiometry control for higher methane yield, longer catalyst life, fewer shutdowns, and actionable data for troubleshooting and optimisation.
Real-Time Hydrogen Analysis
The Fast Sense hydrogen analyzer enables real-time quantification of hydrogen concentration in biomethanation reactors under harsh industrial conditions. The system uses a nanomaterial-based sensing platform designed for operation in humid, H₂S-rich environments typical of anaerobic digestion processes.
The analyzer provides continuous measurement of hydrogen levels across a wide concentration range, supporting process optimization and safe reactor operation.
The platform allows integration into existing plant control systems through standard industrial communication interfaces and analog outputs. Its modular architecture enables remote firmware updates, calibration management, and cloud-based data visualization, allowing operators to monitor reactor conditions and sensor health in real time.
The analyzer is designed for challenging biogas environments with fluctuating gas composition, high humidity, and intermittent reactor activity. Applications include monitoring hydrogen injection during biomethanation, detecting low-ppm hydrogen buildup in digesters, and providing feedback for process control systems that optimize methane yield.
By enabling continuous hydrogen monitoring, the system supports improved gas conversion efficiency, early detection of process instability, and safer operation of hydrogen-assisted biogas upgrading systems

Case Studies
CASE-A
Biomethanation
Biomethanation converts organic waste into biogas. Injecting hydrogen can increase methane production. Sensors must handle humidity, H₂S, and fluctuating levels.
CASE-B
Hydrogen Detection in Air
Essential for early leak identification, safety monitoring, and prevention of fire or explosion risks at low ppm concentrations.
