An overlooked challenge in methane emissions monitoring: background concentration isn’t just background

Methane emissions monitoring is evolving rapidly, with drone-based surveys providing more accurate and reliable solutions than ever before. However, one critical challenge remains: How do we correctly account for background methane concentrations in the atmosphere? And how do we subtract them correctly in the reported emission rate? At Explicit, we’ve spent over a decade conducting […]
Rethinking methane emissions monitoring: It’s not about the leaks

When we talk about methane emissions, the conversation almost always starts with leaks. How to find them, measure them, and mitigate them. At a methane mitigation conference last year, this talk was all the same: leaks, leaks, leaks. As if insufficient maintenance protocols were the root cause of the world’s climate crisis. We beg to […]
Measurement validity: a frequently overlooked key to accurate methane emissions monitoring

A common question in emissions monitoring is: “What’s your measurement uncertainty?” But a far more important—and often overlooked—question to answer is: “How do you know if your measurements are valid?” Without verifying the validity of your sample, you’re essentially sampling blind. You might as well be guessing. And yet, even experienced professionals who work with […]
Why wind also matters in methane emissions monitoring

When discussing methane emissions monitoring, the focus is often on gas concentration: how much methane is emitted and from where. But if you want accurate, actionable measurements, another factor deserves just as much attention: wind. At Explicit, we specialize in accurate emissions quantification, and one thing is clear: understanding wind dynamics is just as crucial […]
Fast-growing Danish greentech company secures large-scale contract with Equinor to survey methane emissions using drones

Explicit ApS, Danish greentech scaleup and pioneer in the use of drone technology to monitor greenhouse gas emissions, has secured a multi-million EUR contract to survey methane emissions from all Norwegian assets on behalf of Equinor Energy ASA in 2025. The contract includes survey of 39 offshore platforms located on the Norwegian continental shelf and […]
DFM – Offshore platforms

Explicit quantified CH4 emissions from multiple TOTALEnergies offshore platforms using the Drone Flux Measurement (DFM) method. Thanks to its easy implementation, the DFM method can be used to quantify emissions also over sea. In this scenario, Explicit develops detailed maps which help the pilot to safely operate the drone offshore.
Flare Efficiency (FlareE)

The purpose of Project FlareE is to develop and demonstrate a new measurement methodology – based on in-situ sampling directly in the flare plume using drones equipped with gas analysers (also known as ‘sniffer drones’) – to measure and express flare Destruction Removal Efficiency (termed DRE) of methane in an operational environment. Read more about […]
FUMES

The Fugitive and Unburned Methane Emissions from Ships (FUMES) project, a collaboration between the International Council on Clean Transportation (ICCT), Explicit ApS, and the Netherlands Organization for Applied Scientific Research (TNO), collected the most comprehensive dataset of real-world methane emissions from LNG-fueled ships to date, including methane slip from marine engines and fugitive methane emissions […]
DFM – Biogas plants

Explicit measured CH4 emissions from several biogas plants located in Denmark using the Drone Flux Measurement (DFM) method. By requiring only a single field operator, the DFM solution is easy to implement and does not interfere with site operations. Instant feedback is provided to the manager in the event of abnormal CH4 leaks. A detailed emission […]
New drone-based method for quantifying fugitive methane emissions at site level achieves international accreditation

Explicit ApS, one of Europe’s pioneers in the use of UAV technology to monitor emissions, has achieved ISO 17025 accreditation on a new drone-based method to quantify fugitive methane emissions at site level. The accreditation, the first of its kind in the world, provides the oil gas industry with a path to independently verify methane […]
