Energy Department Backs Advanced Hydrogen Storage Projects

The U.S. Department of Energy (DOE) has announced up to $4.6 million for four projects to develop advanced hydrogen storage materials that have the potential to enable longer driving ranges and help make fuel cell systems competitive for different platforms and sizes of vehicles. The DOE says advanced hydrogen storage systems will be critical to the widespread commercialization of hydrogen and fuel cell technologies.

The awardees include the following:
     Â
Ames Laboratory of Ames, Iowa, will receive up to $1.2 million to investigate the development of novel high-capacity silicon-based borohydride/graphene composite hydrogen storage materials produced through mechanochemical processes. If successful, this project will develop reversible, high-capacity hydrogen storage materials with sorption kinetics, sufficient to achieve the DOE system targets.
     Â
The California Institute of Technology of Pasadena, Calif., will receive up to $1 million to develop novel high-capacity hydrogen sorbents based on high surface area graphene. The DOE says improved sorbents with higher volumetric capacity will allow for more optimal system design and improve total performance over current materials, making hydrogen sorbent systems a more viable option for practical applications.

Texas A&M University of College Station, Texas, will receive up to $1.2 million to develop new low-cost hydrogen sorbents that have high hydrogen sorption capacities that exceed the “Chahine rule” or the expected hydrogen adsorption per unit of surface area. The DOE says improved sorbents with higher volumetric capacity and improved thermal conductivity will allow for more optimal system design and improve total performance over current materials, making hydrogen sorbent systems a more viable option for practical applications.
     Â
The University of Michigan of Ann Arbor, Mich., will receive up to $1.2 million to develop “best in- lass” hydrogen sorbent materials, with a focus on achieving simultaneously high volumetric and high gravimetric densities. This project is expected to lead to further improvements in hydrogen sorbent systems for onboard vehicle use.
