  1. Solid hydrogen is the solid state of the element hydrogen, achieved by decreasing the temperature below hydrogen's melting point of 14.01 K (−259.14 °C; −434.45 °F).

  2. Mechanical - Solid hydrogen is known to behave as almost a hydraulic fluid at temperatures near its melting point, with a measured shear strength of approximately 5 atm at about 10 K. The strength varies with temperature, such that at liquid helium temperatures and below the solid is at least a factor of 2 stronger and harder; its degree of ...

  3. 21 Ιουλ 2016 · The solid hydrogens are dominated by quantum effects, the most out­ standing property being that the rotation of the molecules is free down to the lowest temperatures, in the sense that the rotational quantum number J characterizing the rotational motion of the free molecules remains a good quantum number in all of the solid-state phases ...

  4. 1 Ιαν 2021 · This chapter summarizes the current potential of the solid-state hydrogen technology in the renewable energy sector and potential paths to engineer the next generation of materials along with their hydrogen thermodynamic and kinetic paths.

  5. 2 Ιαν 2024 · They suggested the maximum hydrogen storage capacity at room temperature strongly depends on the VEC of the HEAs: the capacity is high (1.52.0H/M) for low values of VEC (<4.9) whereas, a drastic fading is observed for VEC ≥4.9 which is the case for alloys with M being a late 3 d transition metal.

  6. 6 Οκτ 2020 · Here, we present a fast interatomic potential, which reproduces the molecular hydrogen phases: orientationally disordered Phase I; broken-symmetry Phase II and reentrant melt curve. The H 2 ...

  7. Solid hydrogen carriers (SHC) and in particular metal hydrides (MH) are a commercially viable alternative to compressed or liquid gas hydrogen storage solutions. SHC allow to safely store hydrogen with high purity (7.0), at low pressures (1 to 40 bar), in a very compact manner (up to 150 kg H 2 /m³ compared to 39 kg H 2 /m³ for hydrogen at
