To date, there are several possible valuation routes. The injection of biomethane into the natural gas network and cogeneration are the two recovery solutions most used in France and internationally: Biomethane injection: The biogas produced by the anaerobic digestion unit undergoes an operation aimed at eliminating undesirable compounds (water, hydrogen sulphide, carbon dioxide, etc.) to keep only the biomethane. The latter is then compressed, odorized and then injected into the distribution network (GrDF) or transmission (GRT). The existing purification processes can be of several types: the membrane process, adsorption (PSA), washing with water, etc. Biomethane can be sold under purchase obligation contracts since 2011. Naskeo has several references in injection and offers turnkey purification solutions adapted to your project for flow rates ranging from 50 Nm3 / h to 500 Nm3 / h of biomethane. Cogeneration : The biogas after dehumidification and desulphurization is compressed and injected into a cogeneration engine. The engine supplies a generator producing electricity which is injected into the Enedis network. The heat is recovered from the engine and exhaust gas cooling circuits to supply the anaerobic digestion process and for external heat use activities (livestock buildings, housing, industries, etc.). The cogeneration unit can be installed in a soundproof container or in a room depending on the characteristics of the site. The electricity produced can be sold through a purchase obligation contract for a period of 15 years. Naskeo has around thirty cogeneration references and offers cogenerator ranges ranging from 80 kW to 1.2 MW with high levels of energy performance. Other biogas recovery solutions that are less present in the territory: Vehicle natural gas: to be used as vehicle fuel, biogas undergoes a series of purification and compression stages. This valuation has developed a lot in Sweden and Switzerland. In France, this recovery can be considered within the framework of a captive fleet of vehicles (Bus, waste dumpsters, etc.) The combustion of biogas in a boiler for the production of heat, envisaged mainly on industrial sites. The recovery of CO2 in biogas for industrial recovery is envisaged for large-scale projects (minimum 250-300 Nm 3 of CH 4 / h) by injection with biogas purification.
