#GeoscienceAustralia has identified a thick salt deposit in outback Queensland's #Adavale Basin as a potential underground #hydrogenbattery.

The Adavale Basin sits below the towns of Quilpie, Blackall and Charleville, and the largest underground freshwater reservoir in the world — the #GreatArtesianBasin (GAB).

Underground 'battery' deep in the outback could power millions of homes

They are older than the dinosaurs and buried deep underground, but scientists are pinning their hopes on ancient salt caverns to solve Australia’s green energy storage problem. 

The Hydrogen Stream: Japanese researchers develop low-temperature hydrogen battery

Institute of Science Tokyo researchers proposed a battery with magnesium hydride (MgH2) as the anode and hydrogen (H2) gas as the cathode. Meanwhile, researchers at Chung-Ang University proposed chloride-resistant ruthenium (Ru)-based nanocatalysts for direct electrolysis and hydrogen production from seawater.
