Implication

Geochemical modelling reveals substantial thermogenic hydrogen generation from overmature source rocks in the Cooper Basin, suggesting viable natural hydrogen resource potential.

Key Points

To evaluate the generation potential and distribution of thermogenic hydrogen gas produced from overmature, land-plant-derived organic matter within the Cooper Basin.
Integrated chemical kinetics of hydrogen generation into a petroleum system modelling framework for the Cooper Basin.
Modelled thermal maturation, gas generation, and in-situ yields across coals and shales of the mid-Patchawarra Formation, focusing on the deep Nappamerri Trough.
Free hydrogen gas generation initiates at high thermal maturities exceeding 3.5% vitrinite reflectance.
Modelling predicts a high-volume hydrogen sweet spot deep in the Nappamerri Trough, with in-situ free hydrogen concentrations comparable to methane concentrations in productive unconventional shale gas plays.
The deep geological hydrogen play system remains largely untested due to sparse exploratory drilling within the basin depocentre.
