Ancient Queensland salt caverns could become Australia’s clean-energy backbone
Geoscience Australia’s $31 million drilling of the Adavale Basin in outback Queensland identifies the Boree Salt deposit as thick enough to form underground caverns by dissolving salt, creating a storage space for hydrogen (or compressed air). This geological-scale energy reserve could store around 6,000 tonnes of hydrogen per cavern (~100 GWh), potentially powering tens of millions of homes for a day with a handful of caverns, complementing intermittent renewables.
