Model-Based Optimization of Hydrogen Storage for Military Ground Vehicle Applications

by Ben Paczkowski; Andrew Wiegand


As the Army begins to explore the electrification of its ground vehicle fleet, several technologies are of interest to help clear the large hurdle presented by vehicles’ energy needs. Hydrogen fuel cells have potential as a solution to this problem but there are many challenges that need to be addressed, such as hydrogen storage. Siemens LMS Amesim was used to simulate the performance of several wheeled and tracked vehicles in order to evaluate several hydrogen storage methods and materials to determine if they are suitable for military ground vehicle use. Several technologies were found to perform better than the state of the art compressed gas storage, exemplifying that advanced hydrogen storage could enable the electrification of the heaviest ground vehicles in the Army’s fleet.
