Overview of Hydrogen Sorbents

NREL led DOE's Hydrogen Sorption Center of Excellence (HSCoE) and is continuing to evaluate sorbents for use in hydrogen storage applications. Of all material solutions being evaluated today, sorbents provide the only on-vehicle refueling option, can easily be integrated into existing pressurized hydrogen storage systems, and can substantially reduce storage system costs while increasing capacities compared to present high-pressure storage systems. NREL will provide a summary of the accomplishments and recommendations from the 5-year HSCoE efforts. This will include details of the different activities and results, as well as discussions of present and future R&D. The goal of these activities is to develop materials that can meet DOE's targets for vehicular fuel cell and other early market applications. Funding for this effort was provided by the US Department of Energy's Office of Energy Efficiency and Renewable Energy as part of DOE's Fuel Cell Technology Program under subcontract DE-AC36-99GO10337 to NREL.
