• Resumen

  • The article discusses how Wendy and David Mao of the University of Chicago and the Carnegie Institution conducted research to combine compressed crystals of hydrogen and water or methane with a so-called diamond anvil. They proceeded to cool them with liquid nitrogen. Storing elemental hydrogen for use as a clean fuel requires impractically low temperatures or high pressures. In one instance, the result was a hydrogen-water clathrate, or cagelike crystal, that retained its 5.3 percent hydrogen by weight when it returned to atmospheric pressure.
