Summary
Impact of geochemical alteration on carbon dioxide stability in the subsurface. This project aims to investigate the reactive behaviour of carbon dioxide in sandstone rocks to improve the safety of carbon sequestration operations. The project will develop new techniques to link fluid flow behaviour and geochemistry analysis, using high resolution 3D microscopy within geologic samples. The results will demonstrate the level of stability and security of carbon dioxide in underground sandstone rock ....Impact of geochemical alteration on carbon dioxide stability in the subsurface.

The project will develop new techniques to link fluid flow behaviour and geochemistry analysis, using high resolution 3D microscopy within geologic samples. The results will demonstrate the level of stability and security of carbon dioxide in underground sandstone rocks, and lead to safer design of sequestration operations.Read moreRead less
Maximising carbon sequestration in freshwater wetlands. Maximising carbon sequestration in freshwater wetlands. This project aims to determine how manipulation of wetland hydrology can alter sulphur and iron cycling to inhibit methane emission and improve wetland net-carbon sequestration. Wetlands are among earth's most efficient ecosystems for carbon sequestration, but methane emission can offset this capacity. Redox cycling of sulphur and iron in wetlands can inhibit methane emission, but the ....Maximising carbon sequestration in freshwater wetlands. Maximising carbon sequestration in freshwater wetlands. This project aims to determine how manipulation of wetland hydrology can alter sulphur and iron cycling to inhibit methane emission and improve wetland net-carbon sequestration. Wetlands are among earth's most efficient ecosystems for carbon sequestration, but methane emission can offset this capacity. Redox cycling of sulphur and iron in wetlands can inhibit methane emission, but the precise biogeochemical processes and their efficiency are very poorly constrained due to a lack of studies—especially in Australian freshwater wetlands. This project is expected to inhibit methane emission in freshwater wetlands and maximise their net carbon sequestration efficiency.Read moreRead less
