Hydrogen is proposed as a low carbon, versatile and energy-dense fuel of the future that will be seen to drive transportation, heat our homes and provide power to many industrial applications. National and commercial organisations around the world are pivoting towards the opportunity to develop a new hydrogen energy infrastructure and fill links in the supply-to-use value chain. A hydrogen economy will be a fast-moving, global enterprise requiring an agile infrastructure that can source and deliver hydrogen in large quantities at short notice. Large-scale distributed storage reserves will be key to smoothing out the variations in supply versus demand over time. Subsurface geological storage of natural gas (Methane) currently achieves this on a seasonal basis for major population centres around the world. Pore space (void space) within sedimentary rock is ‘real estate’ for the temporary or permanent containment of fluids. Pore space aggregated over cubic kilometres of rock, hosts hydrocarbon accumulations, groundwater, CO2, in the context of Carbon geostorage, and geothermal fluids cycled to provide heat or a working fluid for power generation. It is hoped pore space (e.g., aquifers and depleted hydrocarbon reservoirs) will also host hydrogen as part of large-scale temporary storage in the hydrogen energy supply infrastructure of the future. However, given there is limited experience with hydrogen naturally occurring in the subsurface, there are many unknowns regarding the capability of such systems to host and retain hydrogen. Several studies have shown that hydrogen may disturb geochemical and microbiological equilibrium conditions of the system, that may result in the dissolution of the rock and/or the precipitation of solid particles, blocking the pore throats. Also, hydrogen is far less dense, less viscous and more mobile than other fluids more familiar to practitioners of subsurface fluid operations.

In this PhD project, we intend to develop multiscale and multiphysics simulation models that in particular consider the physiochemical property of hydrogen, hysteresis and its geochemical and microbiological interaction with rock and existing reservoir fluids. The model together with robust optimization algorithms will be used to assist with selecting and preparing prospective sites and managing storage systems that often involve frequent injection/withdrawal cycles while considering integrity and geological and phenomenological uncertainty. The developed package will be tested against a number of potential project scenarios, provided by the sponsor.
