Abstract

Solid-state hydrogen storage is the key to environmentally-friendly fuel economy. Several reports have demonstrated adsorption within micropores can densify hydrogen past the solid phase [1] moving the field closer to practical hydrogen storage. However, determination of adsorbate hydrogen density is difficult, expensive and time-consuming. Semi-empirical modelling can provide an estimate of density from gas sorption isotherms. To simplify/automate this process, two MATLAB functions were developed to calculate the adsorbate density and heat of adsorption directly from gas sorption data. These were used to identify material properties leading to greater hydrogen density to facilitate the rational design of microporous carbon materials for nano-composite hydrogen storage vessels.
