Project Description

Project Image   Solid-State Hydrogen Storage

This project will develop a method for converting metals to metal hydrides at low pressures for hydrogen storage systems with high efficiency with respect to volume and weight. 

Availability of a safe, low-pressure, lightweight, compact hydrogen storage system is an enabling technology for hydrogen electric fuel cell usage for space exploration and advanced aircraft electric propulsion systems.  Titanium hydride is being be used as a model material for proof of concept.  Other hydrides with more hydrogen per unit mass will then be evaluated.  Ultimately, nanostructured materials (such as carbon nanotube sheets) with potential to store large quantities of hydrogen in a very small volume will be explored.
