With the commercial introduction of fuel cell-based power systems and the proliferation of hydrogen as a fuel gas, nontraditional hydrogen storage systems are becoming more prevalent. Therefore, there is a need for the dissemination of information on these alternative hydrogen storage technologies.
The scope of this publication includes hydrogen storage systems in which the hydrogen is absorbed in reversible metal hydrides and for which the system is designed to permanently contain the solid material so only hydrogen gas is introduced into or removed from the system. This publication provides guidance to regulatory authorities, manufacturers, and users for the classification and labeling of these systems.
