An essential factor in the more widespread utilization of hydrogen as an energy carrier is economical storage. Metal hydrides are also routinely used in tritium (3H) processing to recover low concentrations of hydrogen isotopes from dilute streams. A typical configuration involves impurity decomposition (or cracking) over a metal getter to liberate hydrogen followed by absorption on a metal hydride bed. While such systems are presently uneconomical for hydrogen energy applications, they are an example of successful implementation of hydrogen storage technology and present opportunities to study material properties that affect performance. Ongoing research has focused on the development of metal hydrides that are reusable, resist degradation, and can be used in the presence of common gases such as nitrogen.
