Vehicle-mounted spectroscopy system detects methane in real time
Researchers have developed a vehicle-mounted spectroscopy system that can reliably detect methane in real time while driving. Using a moving vehicle to detect methane could make it easier to locate hidden methane emissions across large areas.
Researchers have developed a vehicle-mounted system capable of real-time methane detection using dual-comb spectroscopy. This technology could help locate hidden methane emissions across large areas by detecting leaks from natural gas infrastructure, livestock farms, landfills and coal mines. The system, based on mid-infrared dual-comb spectroscopy, can identify simulated gas leaks and map gas-diffusion distribution in outdoor settings.
Equipped on SUVs, it could cruise residential streets day and night, capturing methane concentration, GPS coordinates, and notifying maintenance crews of any underground gas leaks. The technology could assist cities and industries in quantifying greenhouse gas emissions, supporting emissions-reduction policies. More accurate methane leak localization enables targeted repairs, reduces resource waste and improves air quality.
The researchers aim to further enhance the system's performance by expanding spectral coverage and miniaturizing it for drone applications.
