Rapid Leak Detection Prevented Potential Revenue Loss of $200,000 at Biogas Site
Overview
Roeslein Alternative Energy, a major U.S. RNG producer, implemented Qube's continuous monitoring system to optimize biogas capture from covered lagoon digesters. Shortly after deployment, Qube’s CH4 sensors detected emissions from one of the lagoons and localized the source. Operators were notified and repairs were made. Continuous monitoring verified that emissions returned to baseline levels thus confirming the repairs were successful.
Key Challenges
Farm-based biogas plants typically experience 4.8% methane leakage
RNG commands a premium price (15-20x above conventional gas)
Traditional inspection methods are inefficient at detecting leaks promptly
Significant revenue loss from undetected leaks
Solution Implementation
Deployed six Qube monitoring devices around each covered lagoon
Utilized automated software with historical wind data for optimal placement
Implemented digital grid system with 30 source points per lagoon
Established automated leak alarm notifications system
Key Results
Leak Pattern Discovery
5% of detected leaks accounted for 55% of total emissions over 9 months
Leaks occurred at irregular intervals and varying emission rates
Critical Incident Example
System detected a significant midnight leak in August
Quick response enabled next-day repair of a 3-inch tear
Prevented potential revenue loss of $200,000 (if left undetected for a week)
Operational Improvements
Reduced time spent on manual inspections
Improved response time for leak detection and repair
Enhanced accuracy in leak location identification
This implementation demonstrated the significant value of continuous monitoring in maximizing biogas capture and preventing revenue loss in RNG operations.
