Hydrogen and Salt

Hydrogen for energy storage and transport is a key part of the energy transition. Caverns in salt formations can provide high integrity and large-scale storage. Australia has several basins with thick salt in the subsurface that are prospective for underground hydrogen storage and Geoscience Australia’s archive of digital data and physical samples is a crucial resource in assessing these deposits and finding more. New models for the deposition of giant salt deposits, new technologies and the new energy landscape make salt and hydrogen an exciting research frontier.
