Repeated emission spikes during truck loading were traced to oxygen entering the vapor recovery unit and shutting it down. Rerouting the vapor line fixed it.

Diffuse methane emissions at an unlined RNG lagoon evaded standard walking surveys because the gas passed through soft soil before surfacing at low concentrations. Qube's continuous monitoring detected the leaking seams, allowing targeted soil compaction that lowered measured emissions by 67%.

Monitoring caught a persistent leak from a broken weld on a lagoon cover that walk-by inspections never found. Repairing it cut emissions by 87 percent.

Emissions were climbing even though the flare's temperature looked normal, tracing back to a blower without proper feedback control. Fixing the airflow balance brought emissions back down.

A failing regulator, a leaking hatch, and corroded seals were compounding emissions before equipment damage set in. Catching it early avoided about $9,000 in costs.

After a strong pilot, Maas Energy Works expanded monitoring to 24 more dairy digesters, and these early results show faster leak detection and more gas retained.

Independent FluxLab and EREF trials at a working landfill found Qube the most accurate continuous monitor tested, even under tough weather conditions.
