These guys with UDH and calling it a metal on the basis of its characteristics at both high temps and pressures are playing “word definition games”.
Firstly, an intro to “Metallic Hydrogen”:

Then at 16:23 I learn that *other* materials have similar properties at high temperatures and pressures, so, H is not unique in this regard:
“Other materials/elements exhibit these same kinds of properties under similar conditions of high temperature and high pressure” (IOW, Hydrogen NOT UNIQUE):
Start at 16:32

I don’t understand how one can claim that cold fusion cells attained H(0) ‘status’ if metallic hydrogen requires high pressures and high temperatures.
Notice that Holmlid claims nuclear reactions are “spontaneous” in the H(0) state.
To me, that sounds much more like the formation of a Bose-Einstein condensate where the Coulomb barrier collapses.
