Chemical Hydrogen Storage R&D

DOE's chemical hydrogen storage R&D is focused on developing low-cost energy-efficient regeneration systems for these irreversible hydrogen storage systems. Significant technical issues remain regarding the regeneration of the spent material and whether regeneration can be accomplished on-board. In addition, life cycle cost analysis is needed to assess the costs of regeneration. Currently, borohydride-water systems, magnesium-hydride slurries, and innovation beyond boron are under investigation.

Research is carried out through DOE's Chemical Hydrogen Storage Center of Excellence and Independent Projects overseen by the Fuel Cell Technologies Office.

The status of DOE's chemical hydrogen storage research projects is detailed in the storage section of the Annual Progress Report.
