DUB.ME BIOMETHANE
Desulfurization and upgrading of biogas to biomethane in a single-step, by microbial synthesis
Context
PROSE and LGC have partnered to jointly assess the potential of microbial electrosynthesis cells as biogas upgrading processes for biomethane production. The utilisation of microbial communities capable of reducing CO₂ to CH₄ via electrolysis at the cathode, and oxidising H₂S to elemental sulphur or sulphate at the anode, presents a promising technique for obtaining high-quality, highly valuable biomethane.
Objectives
This project aims to enhance the purification and desulphurisation techniques of biogas derived from anaerobic digestion to obtain high-quality biomethane.
Expected results
The technology must enable the assessment of microbial electrosynthesis (MES) cells as processes that simultaneously facilitate biogas upgrading through ex-situ methanation while ensuring the absorption and desulphurisation of biogas.
Target markets
Energie, gas, methane
Type of transfert planned
Research collaborations with private-sector partners in the energy production and (bio)gas sectors.
