Methane Detection Demonstration
Overview
Through funding from the Alberta Methane Emissions Program (AMEP), Airdar had the opportunity to participate in methane detection tests at Carbon Management Canada’s Newell County facility near Brooks, Alberta in July 2024. Our innovative monitoring technology successfully identified and localized five blinded, controlled methane releases. The results were independently validated by C-FER and demonstrated the reliability of our system. Read the full report here.
Key Results
Successful Detection
All five methane releases were detected within an average of 13 minutes, including the smallest release of 0.91 kg/h methane
No False Alarms
Zero missed detections or incorrect triggers during testing
Accurate Locating
Locations estimated within an average of 7.5 m from the actual release coordinates
Detected Complex Release Scenarios
Changes in release location or flow rate during testing were identified
| Metric | Performance (Range, Average) |
|---|---|
| Estimated Start Time Accuracy | 4 - 31 mins, 13 mins |
| Estimated End Time Accuracy | 0 - 30, 6 mins |
| Time to Yellow Alarm | 0 - 58 mins, 22 mins |
| Time to Orange Alarm | 13 - 103 mins, ave 78 mins |
| Time to Red Alarm | 114 - 215 mins, ave 172 mins |
| Estimated Location Accuracy | 5.1 - 9.8 m, 7.5 m |
| Estimated Release Rate Accuracy | 15 - 88%, 49% |
