In 2010 there were 5,905 biogas plants operating throughout the country: Lower Saxony, Bavaria, and the eastern federal states are the main regions. [74] Most of these plants are employed as power plants. Usually the biogas plants are directly connected with a CHP which produces electric power by burning the bio methane.
Biological methanation takes place in a separate methanation plant. The gas is completely converted into methane before the infeed into the gas grid. The carbon dioxide, produced in a gas processing system, is converted into methane in a separate methanation plant, by adding hydrogen and can then be fed into the gas grid.

Biogas plant model diagram. A bio-energy village is a regionally oriented concept for the use of renewable energy sources in rural areas.The system uses biomass from local agriculture and forestry in a biogas powerplant to meet the complete energy requirements of a village, such as electricity and district heating.
Biogas can be made from substances like agricultural waste and sewage. [ 92 ] [ 93 ] The bio-digester uses a process called anaerobic digestion to produce biogas. Anaerobic digestion uses a chemical process to break down organic matter with the use of microorganisms in the absence of oxygen to produce biogas. [ 94 ]
Biogas production In the biogas upgrading process, CO 2 is separated from the methane to produce a higher quality gas. Industry Electrical power plants Combustion of biomass or biofuel in steam or gas powered generators releases CO 2 as a by-product. Energy Heat power plants Combustion of biofuel for heat generation releases CO 2 as a by ...
The higher concentration of methane in the biogas means that it is a higher grade fuel. [5] In addition to generating biogas, which may be used as a cooking or heating fuel, the Nisargruna plant also produces a weedless organic manure slurry. This slurry has a C:N (carbon to nitrogen) ratio of 12:1 to 16:1 and is a good organic soil conditioner ...
The plant had the capacity to produce 20 megawatts-worth of bioSNG from about 30 MW-worth of biomass, aiming at a conversion efficiency of 65%. From December 2014 the bioSNG plant was fully operational and supplied gas to the Swedish natural gas grid, reaching the quality demands with a methane content of over 95%. [ 16 ]
