IBM T.J. Watson Research Center

IBM’s T.J Watson Research Center is working in conjunction with Harvard University and Princeton University to develop an energy-efficient, self-organizing mesh network to gather data over a distributed methane measurement system. Data will be passed to a cloud-based analytics system using custom models to quantify the amount and rate of methane leakage. Additionally, IBM is developing new, low-cost optical sensors that will use tunable diode laser absorption spectroscopy (TDLAS) for methane detection. While today’s optical sensors offer excellent sensitivity and selectivity, their high cost and power requirements prevent widespread adoption. To overcome these hurdles, IBM and its partners plan to produce a miniaturized, integrated, on-chip version that is less expensive and consumes less power. At a planned cost of about $300 per sensor, IBM’s sensors will be 10 to 100 times cheaper than TDLAS sensors on the market today. By advancing an affordable methane detection system that can be customized, IBM’s technology could enable producers to more efficiently locate and repair methane leaks, and therefore reduce overall methane emissions.

If successful, IBM will create low-cost, low-maintenance methane sensors that can be customized into a distributed methane detection system, giving operators greater flexibility to continuously monitor methane emissions.
