Abstract
The present invention relates to the production of biomethane intended for supplying a natural gas network from n biogas production plants Ii, with i varying from 1 to n, in which each of the plants produces and stores the biogas which is collected at each of the plants via a mobile collection device and the collected biogas is purified so as to produce biomethane which is subsequently injected into a natural gas network. The invention also makes provision for storing the biogas, partially purified biogas, or biomethane in order to ensure the continuity of the supply of biomethane to the network during the collection round.
