Hydrogen (H2) energy has the potential to provide significant benefits to power grids, but industry has yet to extensively explore this new technology.

Clean H2 can be generated from renewable energy surplus without additional energy cost, by using electrolysers to convert electricity into H2.  However, the variability of the input power supplied by renewables can make H2 production less efficient.

Surplus renewable energy can be stored using H2 as a carbon-free energy storage method. However, storing and transporting H2 requires special arrangements due to its low energy density and flammability.

Australia aims to establish itself as a major player in the H2 market by positioning itself as a key exporter.
