The world's largest biogas plant will be put into operation
According to the forecast of the German Biogas Association, by 2020, Germany will have up to 20% of its natural gas demand from biogas supplies. The largest investment in biogas plants that have been put into operation in Germany amounts to 10 million euros and produces 6 million cubic meters of methane per year.
The development of biogas in Germany is rapidly heating up, due to a major breakthrough in the key technologies of this research in 2007, and the injection of biogas into the natural gas pipeline network. It is understood that there are currently 30 biogas production sites in the Cohen region of Germany, which consume 120,000 tons of raw materials each year, mainly cereal crops. Small-scale biogas facilities can also use liquid manure as raw materials. The 8 fermentation tanks produce about 30 million cubic meters of biogas each year. These biogas can be processed to separate nearly 15 million cubic meters of biomethane.
Biogas contains about 60% methane and 40% carbon dioxide, while natural gas contains about 97% methane. For this reason, the biogas field in the Cohen region filters the carbon dioxide in the biogas through a specific chemical washing process under atmospheric pressure to increase the proportion of methane in the biogas. After processing, the purity of biomethane in biogas can reach 99%.
