Methane you capture is credit. Methane that leaks isn’t.
Cairn Sensing puts solar and battery-powered methane sensors around dairy digesters, covered lagoons and gas upgrading equipment, so leaks show up in hours, not at the next inspection.
Free 90-day pilot. No cost, no long-term commitment.
A leak is lost gas and a question about your numbers
Dairy RNG projects earn their value from methane that would otherwise reach the air. Credits under programs like California’s LCFS, Oregon’s Clean Fuels Program and Washington’s Clean Fuel Standard depend on that story holding up.
Torn lagoon covers, leaking seals and venting during upsets are hard to spot on a large, open site. Each one is gas you didn’t sell, and a gap between what you report and what a satellite or a neighbor might see.
How Cairn fits
- Leak detectionSensors near digesters, covers and upgrading equipment flag elevated methane early.
- Fence-line monitoringBoundary sensors show what’s leaving the site and when.
- A record that supports your creditsContinuous readings give you a history to back up how your project performs.
- Built for open groundSolar and battery-powered, reporting over cellular with satellite fallback. No trenching or power runs.
- Alerts at your thresholdYour team hears about a problem when it starts, not weeks later.
How a pilot works
We start with a 15-minute call about your site, what you monitor today and where readings come from.
If it’s a fit, we install a small number of sensors and run them for 90 days at no cost. You get the alerts and the data, and at the end you decide whether it’s worth keeping.
Cairn’s data supports your own records. It isn’t a credit verification service and doesn’t replace the verification your program requires.
