Renewable based biogas upgrading [PDF]
Journal of Cleaner Production, 2019 [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.

Upgrading Biogas to Biomethane
2020Biogas provides a flexible clean and efficient form of energy. Enriched biogas may generate large volumes of bioCH4, allowing its usage as an alternative to natural gas via existing natural gas networks or being used directly as fuel by vehicles. There are two broad categories of upgrade techniques where traditional methods focus on ex-situ upgrading ...
