• Underground Storage of Hydrogen

This works is focused on development of a simulation toolbox to model underground hydrogen storage (UHS) integrated with surface facility design. This work helps in understanding the techno-economic constraints involved in operating a large-scale UHS facility that needs to manage fluctuations in both supply and demand.

• Wellbore decommissioning

This work is focused on repurposing near-to-decommission wellbores for storing hydrogen within the wellbore. This work aims to reduce the storage cost by managing decommissioning expenses for creation of a new hydrogen-based energy storage system and integrate green hydrogen into local economies.

• CO₂ sequestration in underground coal seams

This research involves evaluating cleat/natural fracture system with Australian coal seams using micro-CT scan imaging and studying the impact of coal swelling on permeability change during CO₂ injection. 

• 3D modelling and printing of porous media

This research is focused on designing random porous media using fractal systems and 3D printing.

• Production data and rate transient analysis

This work is focused on analysis of gas and water production data from unconventional resources including coal seam gas and shale gas reservoirs to obtain critical reservoir properties.
