In a method for the methanation of biomass and the energetic use of the biogas obtained in at least one apparatus having a fermenter (1) operating in a batch process, the fermenter (1) is filled with biomass, the loading opening (2) is closed in an airtight manner, methane-rich biogas produced in a fermentation phase is fed into a first gas storage unit (14), at least intermittently, during the flushing of the fermenter (1) with flushing air, low-methane gas mixture is fed into a second gas storage unit (15), at least intermittently, the loading opening (2) is opened and the fermentation residue is removed from the fermenter (1). The energetic use of the gas stored in the second gas storage unit (15) is carried out in such a way that gas removed from this gas storage unit is mixed with the biogas removed from the first gas storage unit (14) before the mixed gas produced in this way is subsequently used energetically.
