Patent number: 8168158Abstract: A base-facilitated process for producing hydrogen. Hydrogen is produced from a reaction of carbonaceous matter with a base and water, preferably through the formation of a bicarbonate or carbonate by-product. The base-facilitated hydrogen-producing reactions are thermodynamically more spontaneous and are able to produce hydrogen gas at less extreme reaction conditions than conventional reformation or gasification reactions of carbonaceous matter. In another embodiment, the instant reactions permit the production of hydrogen from carbonaceous matter without the production of carbon dioxide or carbon monoxide. In a preferred embodiment, the carbonaceous matter is coal or a derivative thereof.Type: GrantFiled: September 15, 2009Date of Patent: May 1, 2012Assignee: Ovonic Battery Company, Inc.Inventors: Benjamin Reichman, William Mays

Patent number: 7393500Abstract: Electrochemical and gas phase hydrogen storage alloy compositions that provide superior performance, especially at low temperature, and excellent cycle life characteristics. The alloys of this invention are AB5 type alloys that include a cycle life enhancement element and a low Co concentration. The preferred cycle life enhancement elements include Zr and Si. The cycle life enhancement elements increase the cycle life of the instant alloys by reducing the pulverization of alloy particles upon repeated cycles of charging-discharging or hydriding-dehydriding. The alloys are characterized by low hysteresis on cycling, where hysteresis is measured in terms of mass concentration difference, a parameter related to the activation energy associated with the incorporation of hydrogen into the alloy. The instant alloys are designed to have a low activation energy for hydrogen incorporation and as a result, provide low hysteresis and a more uniform concentration of absorbed hydrogen within the material.Type: GrantFiled: April 2, 2004Date of Patent: July 1, 2008Assignee: Ovonic Battery Company, Inc.Inventors: Michael A.
