Hydrogen storage materials for hydrogen energy vehicles

This article provides a technically detailed overview of the state-of-the-art technologies for hydrogen infrastructure, including the physical- and material-based hydrogen storage technologies. The Hydrogen and Fuel Cell Technologies Office (HFTO) is developing onboard automotive hydrogen storage systems that allow for a driving range of more than 300 miles while meeting cost, safety, and performance requirements. The density of hydrogen is very low, making it challenging to store sufficient amounts onboard a vehicle to achieve a satisfactory driving range. The spread of hydrogen as a fuel for vehicle propulsion poses several challenges regarding the way we use the energy contained in hydrogen, storing hydrogen on the vehicle and ensuring its availability.
