Project Overview
The WEGHA project utilises the Polda Basin in South Australia's Eyre Peninsula — a world-class geological formation of evaporite salt ideally suited for large-scale underground hydrogen storage. Salt cavern storage offers unmatched capacity, safety, and cycling performance compared to any above-ground alternative.
With a potential storage capacity equivalent to twice the Snowy Hydro scheme, WEGHA represents a generational infrastructure opportunity at the heart of Australia's clean energy transition.
Location
Situated within South Australia's Renewable Energy Zone, the Polda Basin offers direct access to world-class wind resources, major gas pipeline infrastructure, and proximity to industrial offtake markets. The site's geology provides naturally pressure-sealed salt caverns capable of storing hydrogen at industrial scale with minimal surface footprint.
