The U.S. Department of Energy (DOE) develops and maintains systems models for screening the performance of hydrogen storage materials. These models are available for download and use by the broad research community.
The modeling framework was developed by the Hydrogen Storage Engineering Center of Excellence (HSECoE) to quickly and efficiently evaluate various materials-based hydrogen storage systems and compare their performance against DOE light-duty vehicle targets. The modeling approach enables the exchange of one hydrogen storage system for another while keeping the vehicle and fuel cell systems constant.
This framework was used to implement the integrated vehicle, the power plant, and the storage system models. The tool was used across the HSECoE to evaluate candidate storage system designs on a common vehicle platform with a consistent set of assumptions. An additional simplified version of the framework model was also developed that can quickly estimate optimal discharge kinetics, effective hydrogen capacities, system mass and volume, and heat removal requirements of various materials-based hydrogen storage system designs. Parameters obtained from these models can then be used as inputs into the detailed framework models to obtain an accurate assessment of hydrogen storage system performance.
The models are being updated and maintained beyond the life of the HSECoE to benefit research efforts outside of the HSECoE and allow university and laboratory researchers to assess the performance of their materials and compare the results to the DOE technical targets.
Model descriptions, a user’s manual, and presentations detailing the models’ validation are also available. These models are open for use by material developers and storage system designers, but caution should be used when applying these models to materials and operating conditions that have not been validated.
