Im Teilprojekt B1 soll ein 3D numerisches Modell zur Beschreibung des Abbaus von Methanhydraten bei gleichzeitiger CO2-Sequestrierung entwickelt werden. Verschiedene Fördertechnologien und Lagerstätten-Typen werden dabei betrachtet und hinsichtlich ihrer Effizienz geprüft. Durch validierte, mathematische Simulationsmodelle wird die Maßstabsübertragung von Daten aus Experimenten in Labor und Technikum sowie der Literatur erreicht.
Methoden
Mit Hilfe des in der Öl- und Gasindustrie verbreiteten Simulators STARS der Computer Modelling Group Ltd. (Kanada) soll ein endliches Areal im Bereich des Bohrkopfes abgebildet und auftretende Wärme- und Stofftransportvorgänge simuliert werden. Auf Basis dieser Ergebnisse sollen wissenschaftlich belastbare Aussagen über die Funktionsweise, die Funktionstüchtigkeit sowie die Wirtschaftlichkeit der Fördereinrichtung getroffen werden. Im Fokus der Untersuchungen stehen das Mammut-Pumpen-Prinzip und das in-situ Methanverbrennungsverfahren.
Darüber hinaus werden technische Rahmenspezifikationen für einen industriellen Demonstrator festgelegt, der später die Realisierbarkeit der zu entwickelnden Fördereinrichtungen nachweisen soll.
