Geothermal groundwater convection in sedimentary basins like the Perth Basin provides a natural underground heat exchanger that can be accessed without artificial hydraulic fracturing because of high natural permeability.
Our research is organised into three interlinked programs:
Since drilling is necessary, the main opportunity in targeting and exploiting low-temperature geothermal systems is to substantially reduce costs: underground fluid flow convection cells provide a natural transfer of heat to shallower levels.
As a consequence, geothermal power could become more competitive with other forms of power, even in areas with normal or only slightly elevated regional heat flow.
In this way, the centre addresses an overlooked opportunity for broadening the scope of geothermal use in Australia.
