Deep Earth Energy


Professor Ranjith Pathegama Gamage

Research opportunities

Focus areas

Australia is transferring to a new energy economy. Utilisation of the deep Earth for sustainable resource production and waste containment offers exciting opportunities that will be integral to this transition. In tomorrow’s Australia, a thorough understanding of the feasibility of using deep earth resources as part of the solution, together with their expected engineering behaviour and environmental impact, will be paramount to technology adoption by society. In this innovative research activity, we are making important contributions to coal seam gas, shale gas and geothermal energy, through collaborative fundamental and applied research on feasibility assessment and innovative solutions to the technical problems that currently impede progress in the development of alternative deep Earth resources.


Large-scale and sustainable use of the deep Earth to better society and protect the environment.


To pioneer innovative and impactful technical solutions for energy production and waste containment initiatives that utilise the deep Earth.
