In order to increase measurement throughput, a characterization scheme has been developed that accurately measures the hydrogen storage properties of materials in quantities ranging from 10 ng to 1 g. Initial identification of promising materials is realized by rapidly screening thin-film composition spread and thickness wedge samples using normalized IR emissivity imaging. The hydrogen storage properties of promising samples are confirmed through measurements on single-composition films with high-sensitivity (resolution < 0.3 mu g) Sievert's-type apparatus. For selected samples, larger quantities of up to similar to 100 mg may be prepared and their (de) hydrogenation and micro-structural properties probed via parallel in situ Raman spectroscopy. Final confirmation of the hydrogen storage properties is obtained on similar to 1 g powder samples using a combined Raman spectroscopy/Sievert's apparatus.
