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 Hydrogen, Fuel Cells & Infrastructure Technologies Program.
The status of DOE's chemical hydrogen storage research projects is detailed in the storage section of the Annual Progress Report.
