  • Using thermal cameras to visualize gas leaks - Drone

    As a result, special LWIR and MWIR thermal cameras have been developed to detect gas leaks, including, for example, the problematic SF 6, which is 24,000x more hazardous for the environment than the greenhouse gas CO 2. So long as the gas is a selective radiator in the spectral range of the thermal camera and its filter, it will be detected.

  • Natural Gas or Coal: Its All About the Leak Rate - Cool

    Jun 24, 2016The leak rate of natural gas averages about 1.5% of production. Over a 20-year-period, a leakage rate of 1.5% would give natural gas nearly twice the impact on global climate change versus coal. I pick a 20-year period for the calculation because that is taken by many atmospheric scientists to be the window-of-opportunity we have to prevent harmful levels of climate change.
