In-situ Biomethanation for Bioconversion of CO2-to-CH4 using high-rate Anaerobic bioreactor

Project Description

Carbon dioxide (CO2), one of the main compounds in biogas, can be bio-transformed to methane (CH4) by in-situ biomethanation, in which the H2 is directly injected into the existing anaerobic digester. This technology is promising for the production of high content of methane (CH4>95%) or biomethane. This project investigates the potential of application of an innovative integration system of a granular sludge technology equipped with a hollow fiber membrane for treating industrial wastewater coupled with in-situ CO2-biomethanation. This project is in line with the EU strategy to target 10% biomethane in gas grids on a volume basis by 2040.
