Hydrogenotrophs-Based Biological Biogas Upgrading Technologies [PDF]
Biogas produced from anaerobic digestion consists of 55–65% methane and 35–45% carbon dioxide, with an additional 1–2% of other impurities. To utilize biogas as renewable energy, a process called biogas upgrading is required.

Renewable based biogas upgrading [PDF]
[EN]A facility for the upgrading of biogas from the organic matter within municipal waste into biomethane using renewable hydrogen has been analyzed. For it to be fed to the grid, CO2 is to be transformed. Methanation of the CO2 with renewable hydrogen is carried out. Solar and/or wind energy are the power sources for the facility.
