Dr.S.Narayanan|Hydrogen Storage in Nano scale Metal Hydrides

Hydrogen is a highly promising alternative fuel source due to its high energy density and clean combustion products. However, the development of efficient and safe methods for hydrogen storage and transportation remains a significant challenge. One of the most promising options for hydrogen storage is through the use of metal hydrides. Metal hydrides are compounds that can store hydrogen in a solid state, making them a safer and more practical option for hydrogen storage compared to compressed hydrogen gas or liquid hydrogen.

One area of research that has shown great promise in the field of hydrogen storage is the use of nanoscale metal hydrides. Nanoscale materials have a high surface area to volume ratio, which can enhance their hydrogen storage properties. This is because a larger surface area allows for more hydrogen molecules to be adsorbed onto the material's surface, increasing the hydrogen storage capacity.

In the investigation of nanoscale metal hydrides for hydrogen storage, the synthesis of various metal hydrides is typically carried out using different methods, such as chemical reduction, electrochemical deposition, or ball milling. The characterization of the resulting materials includes structural analysis using techniques such as X-ray diffraction, transmission electron microscopy, and scanning electron microscopy. The evaluation of the hydrogen storage capacity of the synthesized nanoscale metal hydrides is performed using techniques such as thermogravimetric analysis, volumetric analysis, or pressure-composition isotherms.

The development of more efficient and practical hydrogen storage systems based on metal hydrides will require a deep understanding of the structure and properties of nanoscale metal hydrides. Furthermore, researchers must identify the best methods for the synthesis of these materials, optimize their hydrogen storage capacity, and evaluate their practicality in real-world hydrogen storage applications.

In conclusion, the investigation of nanoscale metal hydrides for hydrogen storage is a promising avenue of research in the field of hydrogen energy. The development of more efficient and practical hydrogen storage systems based on nanoscale metal hydrides has the potential to drive the widespread adoption of hydrogen as a clean and sustainable energy source.
