CO2 optical sensor for geological storage monitoring

/ Project examples

IDIL Fibres Optiques is collaborating with other 28 partners and research institutes from 17 countries to the ENOS project (Enabling On-shore CO2 storage in Europe) to provide a CO2 optical sensor.

After the success of the COPTIK project, IDIL offers its expertise in the validation of CO2 optical measurement technology for the European ENOS project.

IDIL is involved in managing leakage risks for protection of the environment and groundwater: i.e. geochemical monitoring and potential impact of leakage on potable aquifers, and more specifically, the subtask increasing the TRL of groundwater quality monitoring tools.

For that purpose, IDIL is developping a specific fiber optic probe connected to an interrogator and laser diode using an innovative fiber offering high performance in term of sensitivity and detection speed.

IDIL productSpecific CO2 optical probe
Optical fiberInnovative fiber in chalcogenide glass for the probe
Standard silica fiber for the connection fiber
Fluorescence source4,3 µm

All other requirements upon request: length, outer diameter, connectors, operating temperature, pressure resistance

Launch in September 2016, the main objective of the project is to enable the development of CO2 storage on-shore in Europe in order to prevent large quantities of CO2 from being released into the atmosphere. More information about ENOS

IDIL is developing the optical probe to prove that the CO2 is not returning to the biosphere and to quantify leakage if it does occurs, by direct measurements.
