@article{(Open Science Index):https://publications.waset.org/pdf/10012371, title = {Rapid Discharge of Solid-State Hydrogen Storage Using Porous Silicon and Metal Foam}, author = {Loralee P. Potter and Peter J. Schubert}, country = {}, institution = {}, abstract = {Solid-state hydrogen storage using catalytically-modified porous silicon can be rapidly charged at moderate pressures (8 bar) without exothermic runaway. Discharge requires temperatures of approximately 110oC, so for larger storage vessels a means is required for thermal energy to penetrate bulk storage media. This can be realized with low-density metal foams, such as Celmetâ„¢. This study explores several material and dimensional choices of the metal foam to produce rapid heating of bulk silicon particulates. Experiments run under vacuum and in a pressurized hydrogen environment bracket conditions of empty and full hydrogen storage vessels, respectively. Curve-fitting of the heating profiles at various distances from an external heat source is used to derive both a time delay and a characteristic time constant. System performance metrics of a hydrogen storage subsystem are derived from the experimental results. A techno-economic analysis of the silicon and metal foam provides comparison with other methods of storing hydrogen for mobile and portable applications. }, journal = {International Journal of Energy and Power Engineering}, volume = {16}, number = {1}, year = {2022}, pages = {6 - 10}, ee = {https://publications.waset.org/pdf/10012371}, url = {https://publications.waset.org/vol/181}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 181, 2022}, }
