Can a Gallium, Aluminum alloy play a role in an Aluminum battery? The other element used might be depleted Uranium. Using the Ga,Al alloy to store and transport H2 is very valuable in an energy transitioning world and will find niche uses for certain. We are able to produce Solar, wind energy in sporadic bursts, we must exploit all mens of storing it for use when we want it. All residues are recyclable and using cheap nuclear,solar and wind power the Ga,Al alloy will prove replenishable and recyclable - just what we need!
