Advancements in fuel cell technologies have made hydrogen fueled backup power systems competitive with traditional battery or combustion engine driven generating systems. For larger applications, these systems can require on-site storage of a number of hydrogen storage cylinders. These are typically stored in non-combustible cabinets. Currently, the NFPA 55 document for hydrogen storage does not explicitly address siting requirements for hydrogen cylinders stored in this manner. The primary goal of this project was to develop technical information to support the creation of new NFPA 55 requirements for storing less than 3500 fe of hydrogen in metal storage cabinets.

This project focused on determining the hazard posed by a variety of scenarios involving the release of hydrogen from a storage enclosure and associated equipment. Results of the hazard determination were used to evaluate siting requirements for a variety of threats or targets.
