Advances in efficient hydrogen storage have been reported by Professor Hyunchul Oh in UNIST’s Department of Chemistry, which marks an important advance in future energy systems.

This innovative research centers around a nanoporous magnesium borohydride structure (Mg(BH).4)2), shows a remarkable ability to store hydrogen at high densities even at normal atmospheric pressure. the study Published in Nature Chemistry.

The research team led by Professor Oh has successfully tackled the challenge of low hydrogen. Capacity by leveraging advanced high density absorption technology. Through the synthesis of nanoporous complex hydrides containing magnesium hydride, solid boron hydride (BH)4)2and magnesium cation (Mg+), the developed material enables the storage of five Achieving unprecedented high-density hydrogen storage, in a three-dimensional configuration.

The reported material exhibits an impressive hydrogen storage capacity of 144 g/L per volume, surpassing conventional methods, such as storing hydrogen as a gas. (70.8 g/L). Furthermore, the density of hydrogen molecules within the material is greater than that. Highlight the performance of this novel storage approach.

Professor Oh emphasizes the importance of this development, saying, “Our innovative materials In the field of hydrogen storage, it offers a compelling alternative to conventional methods.” This transformative development not only increases the efficiency and economic viability of hydrogen energy use, but also large-scale hydrogen storage for public transportation applications. I also deal with important challenges.
