About Biogas

Gas Storage

In the digester, anaerobic bacteria convert organic biomass into valuable fertilizers and environmentally friendly biogas. Biogas mainly consists of methane (CH4) and carbon dioxide (CO2). Examples of biomasses are livestock manure and organic residues such as waste fromfood industries. Biogas has a net zero carbon footprint. Thus, biogas is environmentally friendly compared to fossil fuels. The amount of CO2 absorbed when the biomass was created is the same as the amount of CO2 released into the atmosphere when the biogas is produced. Thus, CO2 is part of a closed circuit.

The degassed biomass is a valuable fertilizer and sent back to the farmers. The biogas can be used in a co-generation plant where it is combusted and used for producing electrical power and heat to the existing grid and district heating. Alternatively, the biogas can be upgraded to natural gas quality and distributed to the natural gas grid. The nutrients of the degassed biomass can be further concentrated in Renew Energy’s nutrient recovery process and sold to farmers.
