Prof. Mohammed Abu-Jafar and Dr. Diana Dahliah from An-Najah National University Publish Groundbreaking Research on Hydrogen as a Promising Energy Source

Prof. Mohammed Abu-Jafar and Dr. Diana Dahliah from the Department of Physics at the Faculty of Science, An-Najah National University, have published a significant research paper on hydrogen as a promising energy source in the prestigious International Journal of Hydrogen Energy. The journal, which boasts an impact factor of 8.1, is published by the renowned academic publisher Elsevier and holds a Q1 ranking in Scopus, positioning it as the top journal in its field globally.
The study explores hydrogen as a primary energy source, with a particular emphasis on storage mechanisms—an increasingly critical area of research. The paper investigates the structural, electronic, elastic, optical, phonon, and thermodynamic properties of tetragonal hydrogen storage compounds, specifically Mg₂FeH₅, Ca₂FeH₅, and Sr₂FeH₅.
Key findings from the research confirm the dynamic and structural stability of these compounds, supported by stable phonon dispersion spectra and enthalpy formation analysis. Electronic property calculations indicate that the compounds exhibit metallic characteristics, while mechanical property assessments verify their stability at low energy levels.
Additionally, the study underscores the stability of the phonon spectra of all three compounds, reinforcing their dynamic and structural integrity. The optical properties further reveal a strong potential for hydrogen storage applications. Among the examined materials, Mg₂FeH₅ demonstrated the highest potential, making it particularly suitable for renewable energy applications and sustainable hydrogen fuel storage.
This research marks a substantial contribution to An-Najah University’s distinguished record of scientific achievements, reinforcing its dedication to advancing research and maintaining its position as a leading academic institution on both local and global scales.
