At Lawrence Livermore National Laboratory (LLNL), a National Ignition Facility experimental campaign may have unlocked scientific secrets behind how hydrogen becomes metallic at high pressure.

“Hydrogen properties are still puzzling,” said Lawrence Livermore National Laboratory (LLNL) physicist Marius Millot. “In particular, back in 1935, it was predicted that hydrogen should become metallic at sufficiently high pressure. But, using static compression, our colleagues have yet to find clear evidence for metallization at room temperature.”
