A IoT Based Solution for Gas Leak Map

An innovative solution able to provide real-time gas leak maps for gas network and industrial sites will be presented. This solution is being developed in collaboration by eLichens (a gas sensor leader), CEA LETI (a world-wide level research institute) and GRDF (the French gas distributor leader) and its ambition is to develop:

  • A low cost 10-ppm sensor for CH4 detection
  • A connected station that includes this sensor and allows remote monitoring of gas leak through a web interface
  • A gas leak map computed from a network of connected stations deployed on an industrial site.

This solution will be low cost, easy to deploy and will provide real time monitoring. It will detect gas leaks in real time either continuous or temporary (related to some process or conditions).

Pierre Jallon is the CTO of eLichens. He joined eLichens in 2019 and is responsible of the technology development, IP management, product roadmap and prototyping. He is in particular in charge of the development of the gas leak identification offering for eLichens, from prototyping the solution up to market analysis and strategic positioning of the product. Prior to join eLichens, Pierre has been working with CEA LETI as lab manager in health department and in the field of wearable technology. Pierre used to be part of the scientific staff of CEA LETI, he holds a PhD in signal processing and a MBA with a specialization in innovation management.

eLichens is a based in Grenoble and develop innovative solution based on gas sensors for the industrial safety and the leak detection and repair markets. The offering includes gas sensors, connected stations for remote monitoring of gas leaks and data viewer and analytics to manage networks of these stations, quantify and locate leaks. These solutions are based on unique MEMs based IR emitter that has been developed in partnership with CEA LETI and protected by more than 55 patents. eLichens has successfully produced and sold ten of thousands of sensors in the industrial safety market. eLichens is now extending its offering with a new innovative sensor – called 1 ppm sensor – designed for the leak detection applications on industrial and biomethane sites.
