Performing quantum calculations on a supercomputer, scientists at Pacific Northwest National Laboratory have characterized a material that might allow on-board refueling of hydrogen powered vehicles.
Researchers, led by Maciej Gutowski, looked at different crystalline structures of a compound made up of nitrogen, boron and hydrogen - NBH6 - and found one that might be more stable compared to ammonia borane, a molecular crystal built of NH3BH3 molecules. Ammonia borane can hold a lot of hydrogen but isnt easily reversible – able to be refilled with hydrogen. Ammonia borane, as a storage material, would likely have to be removed from the vehicle and be sent to some sort of processing plant and undergo a reaction to be refilled.
The more stable compound, diammoniate of diborane or DADB, holds more promise for reversibility. Initial thermodynamic properties for the compound indicate that it might spontaneously uptake hydrogen fuel.
