The investigation will take place on the Rolleston-West Gas Project, in the Buckland Basaltic Sequence within ATP 2062, Queensland.
The carbon mineralisation technique is based on a process successfully implemented by Carbfix in Iceland, whose carbon mineralisation project has attracted high profile investors including Bill Gates.
This novel approach to carbon capture and storage (CCS) by capturing the gas in water and injecting the solution into suitable subsurface basalt.
Under the MOU, the companies will examine the feasibility of recreating the promising experiment in Queensland.
In this process, CO2 is dissolved in water and pumped into a favourable rock formations. The solution then reacts with the minerals in the rock to create carbonates such as calcium and magnesium.
In these forms, the carbon is stable and can be expected to remain safe for thousands of years.
According to State Gas, should the investigation confirm the potential of the Buckland Basaltic Sequence to store CO2, the partnership will manufacture hydrogen from gas with may be sourced from Rolleston-West or adjacent Reid’s Dome Projects.
CO2 created through the process will be stored within the Basaltic Sequence underground, creating sustainable, low emission hydrogen.
State Gas executive chairman Richard Cottee said the company was pleased to enter into the hydrogen and sequestration initiative with Rockminsolutions.
“While State Gas remains focused on development of its Reid’s Dome and Rolleston-West gas projects, the carbon mineralisation approach has the potential to be a game changer in the production of low emission hydrogen from gas,” Cottee said.
“A combined gas and hydrogen portfolio would provide significant optionality for State Gas into the future.”
