If it's stable at room temperature wouldn't it make a really high density fuel too?
Metallic Hydrogen can also be a liquid and even a gas, the metallic part indicates it's an electric conductor, not a solid. The "idea" behind metallic hydrogen is that since hydrogen is above the alkali metals in the periodic tables there should be a phase where it behaves like a metal, the state of the phase is not defined as a solid/gas/liquid in fact in all honesty it would exist as all 3 and more. The first produ…

Metallic hydrogen is atomic, recombining two atoms into an h2 molecule releases huge amount of energy. Iirc 4x as much as burning h2 in oxygen.
There's an interesting instructional video about this on Youtube: https://www.youtube.com/watch?v=uZwYMyHlWXk

But your parent and grandparent comments are talking about the fact that the authors theorize it may remain metallic once the pressure is released.
Guys, this is literally the holy grail of high pressure physics!

Technically it's degenerate matter since the atoms do not interact due to the pressure and other conditions, this happens because the electrons would have to follow the exclusion principle under those pressures/densities the electrons basically separate from the hydrogen proton as they cannot occupy the same space and the hydrogen becomes a degenerate matter; a sea of electrons flowing freely through a lattice of pro…
Operating a fuel tank at 1 MPa is tricky. Operating a fuel tank at 400 GPa is ludicrous.
