• Methane leak reduction

  • ...without spending a dime.

    Our sensors are fundamentally less expensive, more accurate, and real-time. The result: Troposphere recovers more gas value than it costs to purchase and operate1 .

  • What we do

    Detect in real-time

    Prism sits directly on your site and remotely and automatically measures for leaks.

    Actionable leak data

    Prism distinguishes between different gases, like propane, ethane, or butane, so your permitted emissions look different than leaks to our system.

    Manage large sites simply

    At larger sites, multiple sensors are deployed around the site. To accurately quantify gases, sensors are paired with an automated trace gas release installed near potential sources.

  • Patented and proven technology

    Our infrared spectrometer detects, identifies, and quantifies methane, hydrocarbons, and other byproduct gases at precisions of 200ppb and higher. The stationary sensors are installed upwind of or around a site’s fenceline, are self-powered, and send data directly to our cloud servers.
