CO2 Biologic Methanation

  • 2020-2022


  • Conversion of biogas into biomethane for injection into the gas network by transforming the CO2 contained in the biogas into methane using renewable H2 generated by produced by electrolysis.
  • To convert renewable electricity into a storable energy carrier in order to improve its management when renewable generation exceeds the demand.


  • Project coordination
  • Identification, selection and adaptive evolution of methanogenic strains
  • Design, construction and scaling of 10L (2021) and 100L (2023) pressurized reactors
  • Validation of bioreactor design at laboratory and pilot scale
  • Techno-economic feasibility analysis
