QLM has been awarded another new patent, US 12,411,153, for accurately determining the flow rate of remote methane leaks. This was done by measuring both gas concentration data and lidar distance data with a single low-power diode laser.
Lidar measurement of methane with complex expensive lasers was pioneered by scientists 50 years ago. It is still commonly applied from airplanes and large installations. But it is complex and expensive, meaning these systems only monitor sites and facilities for methane emissions very occasionally, sometimes only for a few seconds every few months. The science has shown that because of this, most leaks get missed.
Finding and stopping the majority of methane emissions will require low-cost simple systems that can be deployed continuously and without expensive operators and data interpreters. That is what QLM have developed its patented single diode laser lidar to do, find every leak every day everywhere.
