Modelled after nature.

Chemically speaking, biomethane, also referred to as bio-natural gas, hardly differs from natural gas. Both gases mainly comprise methane (CH4). Unlike natural gas, biomethane does not come from fossil sources, but rather is obtained from  biogas, which can be produced in biogas plants on the basis of many substrates like renewable raw materials, liquid manure or organic waste.

Biogas consists of only about 54% of high-grade energy-rich methane, and the remainder is mainly carbon dioxide (CO2), oxygen, nitrogen and trace gases. Thanks to a special biogas conditioning process, it is possible to separate the methane, which can then be flexibly used like natural gas by supplying it to the public gas distribution system for decentralised utilisation.

Most current biogas plants directly supply biogas to a so-called combined heat and power (CHP) station which is located next to the source, i.e, the biogas plant itself. As a result, the heat generated in the process can only be utilised by a heat consumer located in the immediate area.

Feeding biomethane directly into existing natural gas distribution systems represents an ideal method for transport. That is why biomethane is significantly more efficient to use than biogas and a reutilisation no longer has to take place close to the biogas plant.

Biomethan is not only economical but also offers enormous ecological advantages. The carbon dioxide that is released during the production of biomethane does not come from fossil deposits, but is rather withdrawn from the atmosphere. Hence, the production is CO2 neutral.
