Patent number: 8329140Abstract: A method and system for storing and evolving hydrogen (H2) employ chemical compounds that can be hydrogenated to store hydrogen and dehydrogenated to evolve hydrogen. A catalyst lowers the energy required for storing and evolving hydrogen. The method and system can provide hydrogen for devices that consume hydrogen as fuel.Type: GrantFiled: September 11, 2008Date of Patent: December 11, 2012Assignee: Los Alamos National Security, LLCInventors: David L. Thorn, William Tumas, P. Jeffrey Hay, Daniel E. Schwarz, Thomas M. Cameron

Patent number: 8101786Abstract: The reaction of halo-boron compounds (B—X compounds, compounds having one or more boron-halogen bonds) with silanes provides boranes (B—H compounds, compounds having one or more B—H bonds) and halosilanes. Inorganic hydrides, such as surface-bound silane hydrides (Si—H) react with B—X compounds to form B—H compounds and surface-bound halosilanes. The surface bound halosilanes are converted back to surface-bound silanes electrochemically. Halo-boron compounds react with stannanes (tin compounds having a Sn—H bond) to form boranes and halostannanes (tin compounds having a Sn—X bond). The halostannanes are converted back to stannanes electrochemically or by the thermolysis of Sn-formate compounds. When the halo-boron compound is BCl3, the B—H compound is B2H6, and where the reducing potential is provided electrochemically or by the thermolysis of formate.Type: GrantFiled: October 28, 2010Date of Patent: January 24, 2012Assignee: Los Alamos National Security, LLCInventors: David L Thorn, William Tumas, Daniel E Schwarz, Anthony K Burrell
