In efforts to achieve net-zero greenhouse gas emissions (GHG) by 2050, realizing a carbon-netural and decarbonized society, the Japanese government has initiated various projects from developing geothermal energy and hydrogen fuel cells to carbon capture storage.

Domestic and overseas CO2 storage exploration projects include the search for deep saline aquifers, depleted hydrocarbon fields (through EOR or re-purposing for long-term carbon sequestration), and un-mineable coal seams. Since geological storage is the primary focus, attention will be concentrated in this first phase on basins with saline aquifers and depleted fields.

Funded through National Low Emissions Coal Initiative, the Petrel sub-basin had been found to be suitable for the geological storage of CO2. This basin had also been identified to be one of the potential basin storages through a regional site screening study to find prospective basin and potential storage resource calculation using the rapid and cost-effective screening fairway method which maximizes the use of any available data, and helps to high grade fairways for further assessment (Uren et al, 2022).
