Hydrogen storage in carbon-based yne-diamond superstructures
Published on 2026-10-24 by @OXFORD
Abstract: AbstractAmong the materials considered for hydrogen storage via physical adsorption, framework-type carbon allotropes stand out due to their porosity, as well as their resistance to heat and moisture. In this study, yne-diamond carbon frameworks were constructed by inserting linear sp-hybridized carbon units between the sp3-hybridized carbon atoms of a diamond-like lattice, thereby generating a series of progressively more porous structures. Their structural, electronic, mechanical, porosity, an[...]
Our summary: Yne-diamond carbon frameworks were designed by incorporating sp-hybridized carbon units into a diamond-like lattice. The yne-Z2 and yne-Z3 structures showed hydrogen storage capacities of 6.46 and 11.97 wt.% at 77 K and 1 bar. These materials exhibit high performance and mechanical strength, making them promising for hydrogen storage applications.

CFD simulation of enhanced heat transfer and fluid flow during rotational charging of internally finned hydrogen tanks
Published on 2026-10-15 by @OXFORD
Abstract: Abstract High-pressure filling operations in portly-volume Type IV composite storage hydrogen tanks bring about overheating problems that can put the tank structure at risk due to sudden compression of the gas and the Joule–Thomson phenomenon. In this research, with the help of a time-dependent computational fluid dynamics method, an active rotational mixing method was tested to accelerate convection heat conduction in a hydrogen tank with an internal volume of 18.04 m3 and internal fins thro[...]
Our summary: This study investigates the impact of rotational mixing on heat transfer during hydrogen tank charging. A computational fluid dynamics approach was utilized to analyze temperature and density changes at varying rotation speeds. Findings indicate an optimal rotation speed of 30 rad/s significantly improves thermal performance while minimizing overheating risks.
