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.
However, the most efficient form of hydrogen storage still remains an open question. Absorption-based storage of hydrogen in metal hydrides offers high volumetric energy densities as well as safety advantages. In this work technical, economic and environmental aspects of different metal hydride materials are investigated.
The storage was held under a pressure of 20 bar, which results in a combined pressurizes-metal hydride storage system. The storage capacity was 4 kg of hydrogen in 30 kg of metal hydride material. The absorption and desorption tests were carried out over two years.
The main advantage of hydrogen storage in metal hydrides for stationary applications are the high volumetric energy density and lower operating pressure compared to gaseous hydrogen storage.
The hydrogen is stored in a combined pressure and metal hydride storage system. The used metal hydride is a titanium-zirconium alloy belonging to the group of low-temperature intermetallic hydrides . Beyond that, however, there are no successfully developed land-based transportation systems using metal hydrides as hydrogen storage yet.
For a classification of metal hydride storage, a comparison to other hydrogen storage technologies is performed. These alternative technologies include liquid (cryogenic) hydrogen storage, gaseous high-pressure hydrogen storage as well as hydrogen storage in two different liquid organic hydrogen carriers (LOHC) and ammonia.
