Geoscience Australia is exploring the Adavale Basin in Queensland as a potential underground hydrogen storage solution, which could power millions of homes in eastern Australia. The Boree Salt deposit, discovered in 1958, is the only thick salt layer in eastern Australia suitable for hydrogen storage.

A $31 million drilling project collected samples from a 3-kilometre borehole, with results expected in six months. Each cavern could store around 6,000 tonnes of hydrogen, equivalent to energy from 50 super batteries. Local residents express concerns over water safety, but experts believe the underground storage is safe with proper pressure management.
