Comparing continuous methane monitoring technologies for high-volume emissions: A single-blind controlled release study
This study assessed eight commercial monitoring solutions, revealing varying performance in detection and quantification, with some systems underestimating emissions by 74%. While true positive rates were generally high, reliability varied, indicating that more research is needed to understand the strengths and weaknesses of these systems before broader adoption in regulatory frameworks.
Assessing the progress of the performance of continuous monitoring solutions under a single-blind controlled testing protocol
Study evaluating the performance of nine continuous monitoring (CM) solutions for methane emissions through controlled testing. Over 11 weeks, tests involved controlled releases of methane under varying conditions. There were significant uncertainties in emission quantification, with some solutions showing large underestimations and overestimations. The results underscore the importance of regular quality testing for advancing CM […]
