The preceding establishes that the usable capacity of (LiNH2+2LiH) for an LDV fuel cell depends not only on properties of the storage material, such as the thermodynamics and kinetics of desorption and the thermal conductivity, but also on aspects of the system design. We now consider how a generic storage material can be tailored for an LDV to meet or exceed the capacity of hydrogen stored as a pressurized gas at 700 bar or 350 bar. The VSC is highly nonlinear with respect to the five-dimensional materials property input space used by the MHSDT. Consequently, certain combinations of material properties (e.g., high ΔH, low ΔS) create scenarios for which none of the tank materials available in the MHSDT suite of options is compatible with the maximum desorption temperature required to operate the fuel cell through a complete drive cycle. Alternatively, other property combinations, such as low ΔH and high ΔS, yield a maximum required desorption temperature that is low enough (< 80 °C) that residual heat from the fuel cell could be used to drive the desorption reaction. This removes additional balance of plant (heating/cooling tubes) in the hydride bed and makes all on-board hydrogen usable, i.e., no hydrogen must be burned to heat the material. Understanding this complex interplay is necessary to determine which combinations of material properties are required (essentially reverse-engineering a material) or how an existing material must be modified to meet a particular VSC target.
