摘要
We propose a set of thermodynamic guidelines aimed at facilitating more robust screening of hydrogen-storage reactions. The utility of the guidelines is illustrated by reassessing the validity of reactions recently proposed in the literature and through vetting a list of more than 20 candidate reactions based on destabilized LiBH4 and Ca(BH4)(2) borohydrides. Our analysis reveals several reactions having both favorable thermodynamics and relatively high hydrogen densities (ranging from 5 to 9 wt % H-2 and 85 to 100 g H-2/l), and it demonstrates that chemical intuition alone is not sufficient to identify valid reaction pathways.
