Biogas gilt als ein wichtiger Energieträger, der einen zentralen Beitrag zur Energiewende leistet. Im Gegensatz zu Strom aus Wind und Sonne lässt sich Biogas kontinuierlich produzieren. Und vielleicht auch bald bedarfsorientiert? Ein Team internationaler Wissenschaftler unter Beteiligung von Mikrobiologen des Helmholtz-Zentrums für Umweltforschung (UFZ) und Ingenieuren des Deutschen Biomasseforschungszentrums (DBFZ) beschäftigt sich mit der Machbarkeit einer solchen flexiblen Biogasproduktion. Zum Beispiel haben sie herausgefunden, dass die Biogasproduktion über die Fütterungsfrequenz der Anlagen gesteuert werden kann. Größere Zeitabstände führen zu mehr Biogas, schreiben die Forscher in der Zeitschrift Applied and Environmental Microbiology.
