harvard scientists claim to have produced metallic hyrdogen (independent.co.uk)

~theoretically~ it's a metastable superconductor at room temperatures and pressures
If the sample can survive the easing off of the pressure and temperature it would be pretty damn huge

yeah, for one, hydrogen's the best rocket fuel energy-wise but super bulky as a liquid because it's so low in density, only about 4.4 pounds per cubic foot. In this cutaway of the space shuttle main tank, look how much smaller the liquid oxygen tank on top gets to be while holding exactly the same amount of matter.
Figure out how to get metallic hydrogen to hold in that state at room temperature and suddenly rocket tanks can get a lot smaller for the same amount of fuel.

some science duders are sceptical tho
reporting /both sides/
