Patent number: 11141784Abstract: A range of alloys of Mg and at least one of Cu, Si, Ni and Na alloys that is particularly suitable for hydrogen storage applications. The alloys of the invention are formed into binary and ternary systems. The alloys are essentially hypoeutectic with respect to their Cu and Ni contents, where one or both of these elements are present, but range from hypoeutectic through to hypereutectic with respect to their Si content when that element is also present. The terms hypoeutectic and hypereutectic do not apply to Na if it is added to the alloy. The alloy compositions disclosed provide high performance alloys with regard to their hydrogen storage and kinetic characteristics. They are also able to be formed using conventional casting techniques which are far cheaper and more amenable to commercial use than the alternative ball-milling and rapid solidification techniques which are much more expensive and complex.Type: GrantFiled: July 25, 2016Date of Patent: October 12, 2021Assignee: HYDREXIA PTY LTD.Inventors: Andrew Charles Duguid, Kazuhiro Nogita, Xin Fu Tan, John Andrew Taylor

Patent number: 10215338Abstract: A system for discharging hydrogen from two or more hydrogen storage vessels (1A, 1B, 1C) containing solid hydrogen storage material. The system includes at least one hydrogen supply line for connecting the hydrogen storage vessels to a hydrogen demand (3), and energy delivery system (6A, 6B, 6C) to provide heat to the hydrogen storage material in each hydrogen storage vessel to desorb hydrogen from the solid hydrogen storage material, and one or more supply connection conduits (4A, 4B, 4C) for connecting the supply line of lines to the hydrogen storage vessels (1A, 1B, 1C). Each supply connection conduit has a backflow prevention device (5A, 5B, 5C) to prevent hydrogen in the supply line from flowing back into the hydrogen storage vessels (1A, 1B, 1C). Also disclosed is a system for delivering a supply of hydrogen to a hydrogen supply line including a control system (7) to determine the timing of activation of an energy delivery system based (6A, 6B, 6C) on the hydrogen demand in the hydrogen supply line.Type: GrantFiled: July 13, 2016Date of Patent: February 26, 2019Assignee: HYDREXIA PTY LTD.Inventors: Jordan Christopher Pierce, Matthew Campbell Greaves, Stephanie Maya Moroz, Andrew Charles Duguid, Alexander Warner Knight
