Queensland, German academics to research geosequestration

UNIVERSITY of Queensland researchers are looking to form a joint venture with Germany’s RWTH Aachen University to further develop geosequestration.

“The aim is to investigate further technology improvements by injection of the whole flue gas stream, composed of some 13% CO2 and 87% nitrogen, into deep coal seams in Queensland and north Germany and abandoned underground coal mines of North Rhine-Westfalia,” principal researcher Dr Paul Massarotto said.

“In Queensland, both the Surat Basin-Walloons and the Bowen Basin-Rangal and Bandana coal measures will be investigated for this potentially-optimum geosequestration path, as it can do away with the capture costs which are some 75% to 80% of a total project, partly replaced by higher compression costs.”

He said Queensland had a vibrant coal seam gas industry that has already defined vast resources with a current potential to sequester over 3.7 Giga tonnes of carbon dioxide.

“This sequestration capacity is equivalent to over 56 years of CO2 emissions from Queensland’s current and future planned coal-fired power plants to 2020,” he said.

The proposed joint venture follows on from research into geosequestration cost-reduction technology supported by an ARC-Linkage grant and six Australian and international organisations.
