N2 - Within the transportation sector, a necessity towards realizing a hydrogen (H2) economy is its storage for controlled delivery. The U.S. DOE's Centers of Excellence (CoE) in H2 storage have pursued different methodologies (metal hydrides, chemical hydrides, and sorbents), for the express purpose of supplanting gasoline's current > 300 mile driving range. Chemical H2 storage has been dominated by one material, ammonia borane (H3B-NH3, AB), due to its high gravimetric capacity of H2 (19.6 wt %) and low molecular weight (30.7 g mol-1). As such, a number of publications have described H2 release from amine boranes, yielding various rates depending on the method applied. The viability of any storage system is also dependent on efficient recyclability. Within our CoE we have thus endeavored to find efficient base-metal catalyzed AB dehydrogenation pathways and regeneration schemes for the spent fuel from H2 depleted AB. We will present recent results in this vein.
