RINGS

Research into injection of new gases into storage facilities

This RINGS (Research into Injection of New Gases into Storage Facilities) project is being undertaken in collaboration with UPPA (University of Pau and the Adour Region) and Storengy. It seeks to extend the research and to anticipate the disruptions caused by the addition of hydrogen and biomethane to the natural gas flow injected into the storage facilities. They may, indeed, partially interact with the various components of the subsoil, whether aqueous, mineral or microbiological.

Its principle is to reproduce in the laboratory a three-phase system (gas, water, underground rocks), in which micro-organisms extracted from the storage facility are cultured under sub-surface temperature and pressure conditions. The goal is to understand the properties of the storage facility, firstly under current conditions, and then with the addition of different rates of biomethane and/or hydrogen.

Finally, an acceptable maximum rate of hydrogen and biomethane in the injected natural gas will be able to be defined, to ensure that there is no contamination of the water table, and to maintain the sub-surface bacterial flora.
