Ammonia borane (AB) is among the strongest candidates for on board hydrogen storage materials. One of the most difficult problems to overcome regarding storing hydrogen as ammonia borane is the regeneration of AB from the material formed by hydrogen release. We are currently assessing the feasibility of a five step regeneration process in which spent material is digested to BX3 compounds using common HX reagents. Prior to the current report steps four and five were yet to be demonstrated. We will report the successful demonstration of these two steps including relevant kinetic and thermodynamic data. These results as well as an overview of the overall process will be discussed. The William R. Wiley Environmental Molecular Sciences Laboratory is a U.S. Department of Energy (DOE) national scientific user facility located at Pacific Northwest National Laboratory (PNNL) in Richland, Washington. PNNL is operated by Battelle for DOE.
