An Extensive Review on Hydrogen Storage Technologies and its Challenges

This research paper presented a review of different types of hydrogen storage technologies, current gaps and challenges of the hydrogen storage system. Transportation of hydrogen is the biggest task that has been involved in adoption of hydrogen as an import and export of clean energy. It has been categorized into three different approaches to describe the current hydrogen storage technologies i.e. compressed gas storage, solid-state storage and liquid hydrogen storage, and while liquid hydrogen storage relies on freezing temperatures to preserve hydrogen in liquid form, compressed gas storage involves large concentrations of pressurized hydrogen. Higher energy densities and lower operating pressures are potential benefits of solid-state storage, which is made up of metal hydrides, chemical hydrides, and porous materials. This review paper combines a comprehensive study of hydrogen storage technologies and approaches from various research studies. Furthermore, discuss on current gaps, challenges in hydrogen storage and comparing the results, methodologies, and conclusions of several significant papers related to Hydrogen Storage Technologies.
