WebHydrogen. Bengt Sundén, in Hydrogen, Batteries and Fuel Cells, 2024. 3.4.3.2 Compressed cryogenic gas. Cooling down compressed hydrogen gas means increasing the density and more stored gas in the tank. The system is often cooled down to 77 K with liquid nitrogen, increasing the volumetric capacity by three times compared to non-cooled … At low temperatures and at pressures up to around 400 GPa, hydrogen forms a series of solid phases formed from discrete H2 molecules. Phase I occurs at low temperatures and pressures, and consists of a hexagonal close-packed array of freely rotating H2 molecules. Upon increasing the pressure at low temperature, a transition to Phase II occurs at up to 110 GPa. Phase II is a broken-symmetry structure in which the H2 molecules are no longer able to rotate freely. If the p…
