The use of application-specific performance targets and engineering considerations to guide hydrogen storage materials development

• Portable power and material handling equipment as early market technology pathways.
• Engineering based system-level storage-materials requirements.
• Application based targets.

The Hydrogen and Fuel Cells Technologies Office, carried out through the DOE Office of Energy Efficiency and Renewable Energy, maintains a broad portfolio of activities to enable the commercialization of fuel cells across a range of near, mid and long-term applications. Improved, advanced hydrogen storage technologies are seen as a critical need for successful implementation of hydrogen fuel cells in many of these applications. To guide and focus materials development efforts, the DOE develops system performance targets for the specific applications of interest, and carries out system engineering analyses to determine the system-level performance delivered when the materials are incorporated into a complete system. To meet the needs of applications, it is important to consider the system-level performance, not just the material-level properties. An overview of the DOE’s hydrogen storage efforts in developing application-specific performance targets and systems engineering to guide hydrogen storage materials identification and development is herein provided.
