Subsurface Gas Storage (CCS and Underground Hydrogen Storage)

Our research integrates geoscience and engineering capability and expertise to address major challenges such as emission reduction through carbon capture and storage, and future fuels through underground hydrogen storage.

Our subsurface gas storage research provides capabilities that fundamentally address the foundational pillars of the energy transition: energy security (methane), emissions reduction (carbon dioxide) and future fuels (hydrogen).

This research is centred around the:

  • assessment and characterisation of potential geological gas storage sites and systems through desktop, laboratory and numerical modelling studies
  • geochemical and geomechanical impact of subsurface gas storage
  • reservoir modelling and engineering of subsurface gas storage sites
  • seal capacity determination for subsurface gas storage sites
  • well and reservoir injectivity during subsurface gas storage.

Some of our current research activities focus on:

  • geochemistry of H2-water-rock interactions
  • laboratory-based and multivariate mathematical modelling studies for CO2 storage in saline aquifers
  • modelling and simulation of coupled wellbore-reservoir systems for underground hydrogen storage
  • multiscale modelling of geochemical and bio-reactive transport in sedimentary rocks for underground hydrogen storage
  • pore-scale flow visualisation and simulation of CO2 miscible injection for both CO2 storage and enhanced oil recovery.

Our research is of particular relevance to the energy sector, as it enables both the permanent storage of carbon dioxide, in order to reduce CO2 emissions into the atmosphere and the temporary and large-scale storage of renewable and Net Zero energy resources in the form of green and blue hydrogen.
