This report provides the results of a project to plan, design, and test a hydride heat-pump prototype that could eventually be manufactured in the United States. The principle of the hydride pump is to transfer hydrogen between two separate heat exchangers that both contain hydriding alloys. Hydriding alloys are intermetallic compounds that can absorb large quantities of hydrogen gas to form solid metal hydrides. The process can be reversed at room temperatures and modest gas pressures. It is this ability to form into metallic hydrides and then reverse that makes this type of pump so interesting. The system is closed and acts as an energy carrier between two or more beds of hydride. In this way, heat can be conveyed from one source to another without moving parts except the opening and closing of valves to control the flow. The project was successful, and was able to upgrade waste heat from a water stream in an industrial setting by 35/degree/F, with only a minimal operating cost.
