However, these are offset by major improvements in the desorption enthalpy (31% reduction) and thermal conductivity (420% increase). The impact of these competing factors on usable storage capacity cannot be ascertained without a systems model for tank design. Our system modeling reveals that, even though the nanoscale-based material contains 40% less hydride on a mass basis, the reduction in required thermal management results in significant weight and space savings: 10% higher VSC and 25% higher GSC (Table ). Moreover, the sensitivity analysis points the way to inverse material design that can be used to, for example, achieve even more difficult objectives such as exceeding the VSC of compressed gas at 700 bar.
