TECHNICAL TARGETS AND STATUS
Materials-based research offers a long-term solution to the challenge of onboard automotive storage, as well as opportunities for stationary and portable power applications, with the potential to significantly reduce the required storage pressure, increase gravimetric and volumetric capacity, and reduce cost. From 2005 through 2010, the DOE Hydrogen Storage program supported three collaborative efforts—the Metal Hydride Center of Excellence, the Hydrogen Sorption Center of Excellence, and the Chemical Hydrogen Storage Center of Excellence—as well as independent projects that investigated more than 400 materials for potential use in hydrogen storage applications. Analysis activities in the Hydrogen Storage Engineering Center of Excellence (HSECoE) have determined the current status of systems using these materials. HSECoE has also developed spider charts showing three modeled systems for each material class and how they compare against all of DOE's 2020 targets.
