It’s a nostalgic Plume of the Week! This week, we look back to one of our earliest plume images from Sept 2019 taken by an early version of our quantum imaging lidar camera, taken during some controlled release testing. Leak rate: 70 L/min.

We’re pleased to announce closing a £12M Series-A funding & strategic collaboration with #Schlumberger to advance detection & quantification of GHG emissions & flare efficiency. Investors: Schlumberger, Green Angel Syndicate, LondonBusinessSchool-E100, Development Bank of Wales, Quantum Exponential, Newable.

After last week's Series A completion, #QLM is delighted to expand to a 3rd UK site at EPIC (Electronics and Photonics Innovation Centre) in Paignton. New facilities include lab space and a dedicated prototyping suite, enabling close work with associates and #SPLICEProject partners Bay Photonics. epic-centre.co.uk/qlm-bring-thei…

Plume of the Week! Is this one leak or two? From the image on the right, you might conclude it’s two, whereas the images on the left and bottom might indicate it’s just one leak. Need to watch it over a period of time in shifting wind conditions and use analytics to decide.

Our #QLM #PlumeOfTheWeek today features an emission partially hidden by an obstacle - railings running alongside the tank. Even when unable to pinpoint the source, QLM's #TDLidar maps the rest of the plume's concentration and shape vs wind, so leak rate can still be estimated.

Plume of the Week! Tested at the BakerRisk facility in TX, measuring controlled releases of methane. Demonstrated detection/alerting & quantification of loss of containment events and fugitive emissions. Below is one of the methane plumes we imaged – this was a big one – 87 g/s.

It’s a ‘Where's Waldo’s methane balloon?’ Plume of the Week! Can you spot Waldo’s balloon filled with 2% methane? Panoramic image of our lab’s balcony and parking lot made by stitching together several images of the gas imaging lidar camera. Look at the window reflections!

Plume of the Week! (more of a methane “puddle” than a plume) – simulated “garden variety” underground leak. First image of a below-ground leak measured by the QLM camera. It’s a medium-sized BG leak for a gas distribution system, at leak rate of ~1L/min (2 scfh, 0.04kg/h).

QLM welcomes Gavin Lindsay as Head of Business Development. He brings 30 years of tech & commercial experience, having had product/sales/BD leadership positions in the global O&G space. He has and will continue to focus on driving high value solutions for customers.

Plume of the Week! Atmospheric stability affects plumes. CH4 plumes seen by QLM lidar camera. Left plume in stable, daytime “A” conditions; same plume in less stable “B” & “C” conditions (all 70L/min flow). In stable conditions, the plume will travel further before dissipating.

It’s a Plume of the Week photo shoot! Same plume, doing different poses for the QLM camera. This is a controlled methane release of 10kg/hr. This week, out in the field with our collaborators from Schlumberger! #naturalgas #lidar #oilgas #oilandgas #oilandgasindustry #energy

Scenes from this week's work in the field chasing gas leak plumes with the QLM gas imaging lidar camera. What did we see? Stay tuned to our upcoming installments of Plume of the Week to find out...

We finally took a breather to celebrate our successful Series-A funding round and threw ourselves a BBQ at our lab in Bristol! As a globally-distributed company, our remote co-workers were with us in spirit!

Plume of the Week! QLM gas camera image of an underground gas leak coming out of a crack in the sidewalk. Looking at it from the side, with the camera pointing along the ground, the plume is only about 10cm tall, and it’s hugging the ground due to 0 wind velocity at the ground.

QLM welcomes Chris Wardle as Chief Manufacturing Officer to lead QLM's operations & manufacturing. Chris brings over 25 years of experience to QLM, having held senior operations and leadership positions in optoelectronics, volume electronics, instrumentation & aviation/aerospace.

Plume of the Week! Can we see gas behind solid objects? Yes, we see plumes as they ooze through complex obstructions, as below: gas released in tomato bushes. See the silhouette of the nearest leaf in the range image and depth of lidar returns inside the bush.

QLM awarded funding from Innovate UK in “Commercialising Quantum Technology - Feasibility Studies”. 18 months, £500, with Aston University & RedWave Labs to develop a next-gen quantum lidar gas camera using ultra-fast photon counting with detector arrays.

Plume of the Week! Image of an underground gas leak (~1L/min), and we looked at it when the soil was dry, and then when it was wet. Measured flow rate is only slightly attenuated (by about 30%) in wet soil conditions. Gas migration patterns slightly different in dry vs. wet soil.
