The US Naval Surface Warfare Center, Crane Division (NSWC Crane) and the Defense Logistics Agency (DLA) are soliciting research projects to identify novel materials and processes that can provide potential breakthroughs in solid-state hydrogen storage and accelerate the adoption of these technologies by the military.
Many military applications require hydrogen storage and generation systems to be situated in confined spaces or battlefield environments (dust, broad temperature range, sea salt atmosphere, etc.). The objectives of the research program are to significantly increase the readiness of advanced hydrogen storage approaches (including solid-state hydrogen storage materials and systems) and to integrate advanced hydrogen storage systems into vehicles.
Specific areas of interest in the Broad Agency Announcement outlining the solicitation include, but are not limited to, the design, fabrication and demonstration of sub-scale prototype systems utilizing advanced hydrogen storage approaches for Defense applications.
The advanced approaches may include, but are not limited to:
Adsorbents (including the development and use of near-room temperature based doped sorbents);
Chemical hydrides (liquids or solids); and
Advanced physical storage (e.g., cryo-compressed systems or novel concepts beyond conventional high pressure or cryogenic hydrogen tanks).
Storage systems should include all system components necessary for charge and discharge operation including thermal management, reactant flow control, humidification, etc., and that have the following characteristics:
Storage capacity in the range from 0.1 kg to less than 1 kg of hydrogen;
Maximum storage pressure of less than 350 atmospheres to be consistent with current 5,000 psi compressed gas infrastructure, preferably less than 200 atmospheres to avoid the requirement for 5,000 psi tank systems.
Moderate temperature of discharge (less than 150°C).
Discharge rate adequate to power fuel cell stack with between 0.5 kW and 5 kW peak power.
Reversible approaches are preferred that allow rapid charging and discharging of hydrogen storage tanks with minimal waste disposal requirements.
Funding for all awards is a total $1.5 million for 2008, with additional funding subject to appropriations. NSWC expects awards to range between $500,000 and $1,500,000. Proposals may be basic research, applied research, or advanced technology development not related to the development of a specific system or hardware procurement. However, in all cases, applicants should demonstrate that their proposed effort is aimed at high-payoff technologies that have the potential for making, in the 5-10 year timeframe, significant improvements to national security and military operations.
Proposals are due on 23 May 2008.
NSWC and DLA are coordinating hydrogen storage development efforts with the US Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy’s hydrogen storage activities and the National Hydrogen Storage Project.
