CH4 Connections is always a good way to top up on all the tech & regulatory updates in the sector (I think we can call it that now) The main takeaway for me was around how to create alignment on satellite data standards. There has been a huge amount of progress in the sector in recent years. So I now often get these questions: 'What are the detection limits of public satellites', 'why do model providers show different detections with the same dataset' etc Satellites have a huge amount of promise. But it is unclear whether they can match some of the technical claims being made. This highlighted the need for two things: -> How can we align on data standards for satellite data (K. Dana Chadwick did a great talk on this regarding the work at NIST). -> How can we scale up single blind testing of model providers, so we can verify some of the claims being made. This is important right now as the space is in a bit of a greyzone. One of the reasons satellite data is being bought is due to fears of the Waste Emission Charge/Super-emitter programme/Subpart W Combination. Yet many of the claims being made about the technology have not been tested robustly. Things operators can try to do for validation: -> Ask for proof of claims e.g. paper validating methods or an emission distribution curve highlighting detection sensitivity. -> Test the data, try and correlate it with airplanes or ground sensors (not ideal due to temporal mismatches but better than nothing). Aside from this it was also v cool to see the first images from MethaneSAT (congrats on the team for this milestone!).
