Energy from biomethane

The energy carrier is called methane, for both biogas and natural gas. The difference is in the methane content, being at 52 percent for biogas and 96 percent for natural gas. In order to reach this feed-in quality for the German natural gas distribution network, biogas must be cleaned, prepared and compressed.

The advantages of biomethane are at hand. As opposed to fossile energy sources, biomethane is CO₂-neutral. CO₂ released due to energetic utilisation is bound by energy crops during photosynthesizing.  A closed circuit is created without additional CO₂ release harmful to the environment.

As opposed to local generation of electricity in the biogas plant, energy is utilised geographically separated from the generation by feeding into the gas network. Biogas energy is fed to the users via the gas network. This guarantees the highest efficiency and allows a full-year utilisation of electricity and heat where and whenever it is needed. Biogas closes the gap this way between national biogas production and the utilisation in the densely populated areas.
