Construction underway for first HoSt MICROFERM+ agricultural biogas-to-biomethane plant in France
The Netherlands-headed biomass combustion and biogas technology providers HoSt has revealed that construction of its first MICROFERM+ agricultural biogas-to-biomethane plant at a cattle farm in Guichen near Rennes, France is underway. MICROFERM+ plants are specially designed for the on-farm anaerobic digestion (AD) of liquid and solid manure and agricultural feedstock. HoSt acts as a one-stop supplier for this turnkey project of which completion is planned in November of this year.
According to HoSt, it has developed the MICROFERM+ anaerobic digestion (AD) system to give farmers the ultimate possibility to use their agricultural ‘waste’ as valuable feedstock to produce biomethane. It is a turnkey solution for an agricultural biogas plant combined with a biogas upgrading system, using membrane separation technology, and plant control system in a single compact and modular housing.
The project, which was announced in January 2019, is the first of its kind for HoSt in France
Continuous development and collaboration engineering allowed us to combine the biogas plant expertise of HoSt and the biogas upgrading technology of Bright Biomethane, which resulted in the design of the MICROFERM+, said Jean-Sebastien Tronc Commercial Director of HoSt France.
GAEC du Vallon
At the cattle farm ‘GAEC du Vallon’ in Guichen, construction is already in full swing. When ready, some 7 400 tonnes of cattle manure and maize silage will be digested to produce 100 Nm3 biogas per hour. In the biomethane system, the biogas will be upgraded to 55 Nm3 biomethane per hour and injected into the gas grid.
Included in the plant is an efficient heat recovery system. Thanks to the local available service and maintenance team of HoSt, 24/7 technically expert maintenance and spares service can be guaranteed.
According to HoSt, its MICROFERM+ biogas installations are suitable for both liquid waste streams as solid waste streams, which are fed separately into the digester. The MICROFERM+ plant is designed to annually anaerobic digest about 5 000 to 10 000 tonnes of feedstock to produce a maximum of 550 000 Nm3 biomethane.
The remaining post digestion digestate material can be separated or directly stored in an after-storage, to be used as organic fertilizer for crops.
