MT-Energie’s first of eight gas-to-grid (G2G) projects in France, has begun its injection of purified bio methane into the French gas grid.
The company also officially launched the largest biogas upgrading plant with gas injection into the German grid built by MT-Energie.
Explaining the reason why anaerobic digestion is more and more driven by the production of bio-methane and not only electricity, MT-Energie bio-methane expert Timo Vaske said: "Opting for biogas upgrading to bio-methane can be a profitable alternative to traditional CHP concepts, producing only electricity.
"Some countries, such as Germany, France, the UK, Italy, are recognising the contribution of AD to gas self-sufficiency, by issuing favourable incentives.
"In some cases, for example in the eight French projects, the electrical grid connection was also not suitable for the power produced, while the connection to the gas grid was carried out without problems."
Each single triple-tank facility will provide gas treatment capacity of 250 Nm3, which is equivalent to an electrical capacity of around 500 kW.

By GlobalDataThe eight projects, by the end of 2016, will inject over 10.5 M Nm3 per year of bio-methane into the French grid.
MT-Energie is also developing a largest biogas plant with gas injection for SuedZucker, the sugar producer in Europe.
The plant, which can process maize, sugar beet pulp, alfalfa and whole crop silage, will comprise four solid feeders, two secondary digesters, five residue storage tanks and a gas treatment facility with a capacity of 1,400 Nm3 per hour.
Capable of producing a total of approximately 12.2 million m3 of biogas per year, the new biogas plant will generate energy which is enough to power about 6,000 households and 2,000 households with heat.
