Electronic and magnetic properties have been measured and interpreted to assess hydrogen storage capacity for intermetallic alloys. The use of physics, chemistry, and materials science analytical techniques can offer more thorough scientific insight of the role of electronic behaviors essential to promote significant hydrogen storage capability. The measurements on hydrogen storage materials by Thermoelectric Power coefficient, magnetic susceptibility, and the traditional pressure-temperature-composition (PTC) profile assessment techniques have been found to correlate well. These correlations will be described and interpreted their significance on alloy development for hydrogen storage materials will be presented. Thermodynamic bases of these correlations have been established and will be discussed.
