Chemical hydrogen storage allows for a great flexibility and potential for meeting and possibly exceeding the DOE requirements for deliverable weight percent of H2. A series of organic compounds capable of evolving hydrogen at room temperature was studied. Dihydrobenzimidazoles (benzimidazolines) are well known as being easily oxidized and they are able to evolve hydrogen, in the presence of protons, and can be described as organic hydrides. Three derivatives of benzimidazolines were presented, which are capable of evolving hydrogen at room temperature in the presence of acid and catalysts such as finely divided palladium or RhCl(PPh3)3. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
