Locating methane leaks reliably.

Sensirion has developed a stationary methane leak detection system - Nubo Sphere. It is designed as a future-proof, end-to-end solution offering high performance at low total cost of ownership, thus changing the state-of-the-art in methane leak detection. It has never been easier to reliably locate and quantify unintended methane emissions across various industries. The deployment of real-time, continuous methane concentration data enables leak detection much earlier than was previously possible through human interaction, ensuring fast, accurate and cost-saving damage control through rapid incident response actions for increased safety and a reduced environmental burden.

Methane (CH₄) concentrations in the atmosphere have increased by more than 150 % since 1750 and are considered a major contributor to global warming. CH₄ has been identified as an even more powerful greenhouse gas than CO2, making an immediate reduction of emissions necessary. Given its short-lived nature, there are actionable options that reduce the environmental burden on a short timescale. In the US alone, around 13 million tons of CH₄are being released into the air each year - enough to heat ten million homes for a year. Studies show, however, that only about 40 % of CH₄ in the atmosphere originates from natural sources such as volcanoes or permafrost soils, while the remaining percentage is caused by human activities. Reducing that portion of the total CH₄ emissions has thus become a priority for leading nations across the globe, as only then will it be possible to achieve the goals of climate initiatives like the Paris Agreement. And although anthropogenic emissions come from a variety of sources, the oil and gas industry represents the energy sector's largest source of emissions, holding the key to responding to the world's climate challenge.

Relying on Sensirion's market-leading environmental and air quality sensing know-how paired with expertise in scaling solutions into high volumes, Sensirion is therefore developing a stationary methane leak detection system, "Nubo Sphere", for use along the whole oil and gas value chain. It is an end-to-end solution for real-time monitoring of methane emissions, offering high performance at low total cost of ownership. The compact and robust system design enables reliable and highly accurate data from any natural gas infrastructure at all times via data upload to the Nubo cloud. It is fast to deploy and easy to use, while two exchangeable sensor cartridges ensure low maintenance expenses and provide a future-proof, sustainable set-up. The system follows the concept of plug and play: mount the Nubo Sphere nodes on-site and start measuring within minutes.

"With Nubo Sphere, we enable various industries, including oil and gas, to locate and quantify methane leaks reliably and cost-efficiently. Sensirion's offering is unique: cost-efficient yet highly reliable, easy to use and maintain, and based on yet another innovative sensor technology from Sensirion. It makes me very proud to provide the oil and gas industry with the right tool to enable its efforts in methane emissions reduction and thus contribute to stopping climate warming", says Susanne Pianezzi, Sales Director at Sensirion. 

On October 12 and 13, Sensirion will participate in the CH4 Connections 2021 conference in Fort Collins (CO USA) The methane emissions conference will highlight energy industry players promoting methane emissions reductions across the energy value chain as a pathway to a low-carbon world by addressing how effective regulations, science-based methane accounting principles, advances in methane emissions research, and leak detection technologies can accelerate the transition to a low-carbon world.
