Project summary description:
The entX Western Eyre Green Hydrogen Storage project is situated in one of South Australia’s most promising renewable energy zones, which overlays the naturally occurring large salt deposits within the Polda Basin on the Eyre Peninsula, 170 kilometres north of Port Lincoln. entX holds gas storage exploration tenure over the entire onshore Polda Basin.
entX has an active exploration program for salt-bearing formations suitable for cavern development. The activities associated with the onshore Gas Storage Exploration Licence, granted by the South Australian government in November 2022, cover a five-year exploration program focused on geological and geophysical studies, with a commitment to drill a well in each of the two licence areas (GSEL 781 and GSEL 784). The goal of these activities is to reduce geological risks regarding the presence and extent of salt in the onshore portion of the Polda Basin.
While salt deposits are common in many sedimentary basins across Australia, the Polda Basin is considered highly prospective, hosting Australia’s largest drill-discovered salt structure (Kilroo Formation – Diapiric Halite), ideally suited for storage caverns developed through a dissolution leaching process.
A recent report references a study that indicated the cavern energy storage capabilities within the Polda Basin, based on a conceptual design of cylindrical caverns with diameters of 60 meters and 100 meters at depths ranging from 1,650 to 2,000 meters, to be between 240 GWh and 665 GWh, respectively. This has the potential to provide a high degree of utility to the emerging green ammonia, iron and methanol sectors.
