Patent number: 11148947Abstract: A system for controlling hydrogen production from water-reactive aluminum includes a regulator. For example, the regulator may include a plurality of discrete objects and a retainer. Each one of the discrete objects includes aluminum in an activated form reactable with water to produce hydrogen. The retainer may encase the plurality of discrete objects collectively in an elongate shape having an axial dimension greater than a radial dimension. Within the elongate shape, the plurality of discrete objects may define voids therebetween. The retainer may be permeable across its thickness such that water may enter the retainer to react with the activated form of aluminum of the discrete objects in a local concentration that promotes heat generation for rapid reaction while water about the retainer may globally cool the material in the retainer, with the combination promoting rapid and efficient reaction of aluminum to produce hydrogen.Type: GrantFiled: February 16, 2021Date of Patent: October 19, 2021Assignee: LTAG SYSTEMS LLCInventors: Jonathan T.
