Theoretical minimum energy requirements are determined from exergy differences using the standard properties of “normal” hydrogen (25% para-H 2 spin
Potential Roles of Ammonia in a Hydrogen Economy

Ammonia has a number of favorable attributes, the primary one being its high capacity for hydrogen storage, 17.6 wt.%, based on its molecular structure. However, in order to release hydrogen from ammonia, significant energy input as well as reactor mass and volume are
