NOVELTY - Biogas plant comprises: at least one fermenter (1), preferably a dry fermenter for generating biogas; a biogas utilization appliance (2); a first gas reservoir (3) for storing biogas, where the gas reservoir is connected to a first biogas conduit (4) which is connected to a gas outlet of at least one fermenter; and a second gas reservoir (5) for storing biogas, where the second gas reservoir is connected to a second biogas conduit which is connected to the gas outlet of fermenter. The biogas utilization appliance is connected to first biogas reservoir and/or first biogas conduit.    USE - Used as a biogas plant.    ADVANTAGE - The biogas plant: has good thermal insulation; provides a greater surface area for the gas reservoir; and allows improved gas cooling.    DETAILED DESCRIPTION - Biogas plant comprises: at least one fermenter (1), preferably a dry fermenter for generating biogas; a biogas utilization appliance (2); a first gas reservoir (3) for storing biogas, where the gas reservoir is connected to a first biogas conduit (4) which is connected to a gas outlet of at least one fermenter; and a second gas reservoir (5) for storing biogas, where the second gas reservoir is connected to a second biogas conduit which is connected to the gas outlet of at least one fermenter. The biogas utilization appliance is connected to the first biogas reservoir and/or to the first biogas conduit, and to the second biogas reservoir and/or to the second biogas conduit. The biogas plant has a control appliance for controlling the quantitative ratios of the biogas streams conducted from the biogas conduits and/or the biogas reservoirs to the biogas utilization appliance. An INDEPENDENT CLAIM is also included for operating the biogas plant, comprising storing the biogas obtained in a fermenter, which has a methane content of less than a first predetermined threshold value, in the first gas reservoir.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic process flow of the biogas plant during the production of fermentation gas.
