The HySCORE collaboration is a DOE-FCTO funded initiative that brings together internationally recognized leaders in hydrogen storage materials characterization and development from NREL, LBNL, PNNL and NIST. This collaboration is predicated on a synergistic approach to further develop the key core-capabilities necessary for accurate evaluation of hydrogen storage materials capacity, kinetics, and sorption/desorption physio-chemical processes. Furthermore, these experts also conduct a parallel experimental-modeling collaborative approach to utilize the core-capabilities developed in order to rapidly define, model, synthesize and characterize the appropriate materials necessary for achieving the 2020 Hydrogen Storage goals set forth by DOE. The approach is multifaceted to mitigate risk and ensure success as we bridge the gap between physisorption and chemisorption to provide the basis for a new generation of hydrogen storage materials technologies. Our focus is to Develop and Enhance hydrogen storage core capabilities and to Validate claims, concepts, and theories of hydrogen storage materials. The overarching goal is to ascertain pathways and/or new materials that have the possibility to volumetric capacities of greater than 45 g/L and isosteric heats of hydrogen adsorption in the range of 15-20 kJ/mol with the additional caveats of acceptable gravimetric capacities and the ability to deliver on-demand H2 at an appropriate rate and pressure. In order to capture the benefits of reduced system cost and forecourt compression energetics, the maximum overpressure would be <100 bar of hydrogen, with a delivery temperature of greater than 150 K and as close to ambient temperature as possible. 

This talk will outline the advanced characterization techniques, standardized benchmarking/protocols and capabilities. We will also highlight several new materials sets, the impact of the new characterization tools and how this has acceleratd advances in hydrogen storage materials development.
