Industrial Hydrogen End-Use | H₂ Sensors & Gas Analysis for Hard-to-Abate Sectors
Hydrogen sensors and analyzers enable safe hydrogen adoption in steel, cement, refining, and chemical industries through real-time H₂ sensing and gas analysis.
Why Industrial End-Use Needs Hydrogen Sensors
Hydrogen is rapidly becoming a cornerstone of industrial decarbonization. Hard-to-abate sectors like steelmaking, cement production, refining, and chemicals account for nearly 30% of global CO₂ emissions. Transitioning these industries from fossil fuels to hydrogen requires robust safety and efficiency measures.
Fast Sense develops hydrogen sensors, hydrogen analyzers, and H₂ sensing systems that allow heavy industry to safely adopt hydrogen at scale, protecting both workers and assets while meeting emissions targets.
The Challenge in Industrial Hydrogen Adoption
- Steelmaking – Hydrogen replaces coal in direct reduction iron (DRI) processes, but requires precise H₂ analysis to ensure complete combustion and avoid process instability.
- Cement – High-temperature kilns face risks of hydrogen backflow, leaks, and incomplete combustion without accurate H₂ sensing.
- Refineries & Chemicals – Hydrogen is already widely used in hydrocracking and ammonia production, but scaling up requires improved leak detection and process monitoring.
- Worker Safety – Hydrogen leaks in enclosed spaces can become explosive at just 4% concentration in air.
Without continuous hydrogen sensing, these industries face safety incidents, costly downtime, and compliance challenges with new hydrogen regulations.

FAQ's
How do hydrogen analyzers improve steel production?
By ensuring stable hydrogen combustion in DRI processes, preventing instability and yield loss.
Can hydrogen sensors operate in cement kilns?
Yes — Fast Sense sensors are engineered to withstand dust, heat, and vibration in kiln environments.
How does H₂ analysis help chemical plants?
