A method and system for storing and evolving hydrogen (H) 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.

Method and system for hydrogen evolution and storage

The reaction of halo-boron compounds (B&#x2014;X compounds, compounds having one or more boron-halogen bonds) with silanes provides boranes (B&#x2014;H compounds, compounds having one or more B&#x2014;H bonds) and halosilanes. Inorganic hydrides, such as surface-bound silane hydrides (Si&#x2014;H) react with B&#x2014;X compounds to form B&#x2014;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&#x2014;H bond) to form boranes and halostannanes (tin compounds having a Sn&#x2014;X bond). The halostannanes are converted back to stannanes electrochemically or by the thermolysis of Sn-formate compounds. When the halo-boron compound is BCl, the B&#x2014;H compound is BH, and where the reducing potential is provided electrochemically or by the thermolysis of formate.
