Metal hydride hydrogen storage and compression systems for energy storage: modeling, synthesis, and properties

Metal-based hydrides and intermetallic substances offer a practical alternative for storing energy from renewable sources. Given the appropriate adjustment of pressure and temperature constraints, they can absorb and reversibly release hydrogen. They are anticipated to significantly impact the shift towards clean energy and the use of hydrogen as an effective energy carrier. The paper summarizes Energy Storage (ES) methods that use hydrogen and Metal Hydrides (MH). It highlights the findings of the research and development efforts in this field. The emphasis is on carefully choosing MH materials, namely AB5- and AB2-type intermetallic substances, for Hydrogen Storage (HS) and compression activities. This selection is made by analyzing the Pressure-Composition-Temperature (PCT) characteristics of the components in systems containing H2 gas. The article also discusses the characteristics of integrated ES systems that use MH hydrogen storage and compression and the MH-based elements produced at IPCP and HySA Technologies.
