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).
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 ...
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 ...
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.
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 (1.5–2.0H/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 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 ...
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
