The objective of this investigation was to use system modeling to compare the performance of a nanoconfined metal hydride with its bulk counterpart in the context of a specific storage system, in this case one configured for an LDV. We selected the lithium amide/lithium hydride system (LiNH2+2LiH), which can be reversibly cycled according to reaction R1 to yield a theoretical gravimetric capacity of 5.2 wt%. Although additional hydrogen could potentially be released from the bulk material via reaction R2, in practice this is infeasible due to the high temperature required to decompose the stable imide (Li2NH) intermediate.
