Project canary’s analysis of aded testing
Operators want to be alerted right when a leak starts at a facility so they can send a technician out to fix it. But given the significant resources involved in deploying leak mitigation teams, it can be just as important to avoid false alarms or “false positives.” Luckily, there’s a wide variety of incredible technologies and approaches capable of high-fidelity alerting.
Satellite and aerial technologies have conducted single-source blind tests to determine if their technology can accurately detect leaks at facilities at various leak rates. These tests result in a probability of detection (PoD) curve, indicating the required leak rate (in kg/hr) for a 90% chance of their technology detecting the leak. The metrics presented below represent just that: What does the leak rate need to be at a facility for the Canary system to have a 90% chance of correctly alerting an operator? We’ve taken the 2023 ADED testing and normalized the single-blind anonymized, multi-source experiments to a single facility-wide emission event to calculate our 90% PoD. There are countless other ways to present this data, including normalizing for wind speeds (“wind normalized PoD”), requiring that an alert correctly identifies every individual leak at a facility to be counted as a successful outcome (“method detection limit”), and controlling for leak duration.
To be fully transparent, we’ve published every experiment conducted in the 2023 ADED testing campaign, showing if Canary correctly sent an alert about a leak occurring at the METEC facility. Project Canary is technology “F” in the 2023 ADED results comparison below.
