Have a pair of Harvard scientists created the most powerful form of energy storage known to humanity? Hydrogen hit the headlines this weekend, as Harvard researchers Ranga Dias and Isaac Silvera published a paper in Science claiming to have transmuted hydrogen into a solid metal (Observation of the Wigner-Huntington transition to metallic hydrogen). The pair…

Pressure experiment offers tantalising glimpse of metallic hydrogen
For some fuel-cell manufacturers, compressing hydrogen to a liquid has become routine. But for decades, materials scientists have dreamed of going further and forcing hydrogen into a solid metal phase. Metal hydrogen is believed to exist at the heart of gas giant planets like Saturn and Jupiter, and if replicated on Earth could form the…
