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.
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 […]
DFM – Waste water treatment plants
The AWAIRE project, launched in December 2021 and co-sponsored by the Danish Government Ecoinnovation Programme (MUDP), seeks to combine a range of new technologies and methods not previously used for the detection and determination of N2O emissions from WWTPs, included our DFM method. In this case, the drone is equipped with a N2O state-of-the-art microsensor […]
