Ammonia Storage as Complex Compounds for a Safe and Compact Hydrogen Storage

Abstract

Under this project, specifications necessary for the selection of the ammoniated complex best suited to this application were obtained. These included delivery pressure, heat available for operation, ammonia discharge rate required, the desired number of missions and the ambient temperature range for operation. Suitable ammoniated complex compounds were then identified that would provide operation under these conditions. Design software suitable to the evaluation of the complex compounds for this particular application was developed that would determine the size and weight of the complex compound sorber to be used for ammonia storage. In constructing the first prototype storage device, the technology for low mass sorber design for ammonia storage at reduced vapor pressures was advanced using Rocky Research's complex compound technology in a low mass and volume manner. In this first attempt at ammonia storage for the 72 hr, 518 gram NH3 discharge application suitable to the Palm Power 3-day mission application, the resulting sorber weight was 3.06 lbm when discharged. The sorber was capable of providing up to 530 g of ammonia using heat input at temperatures associated with the ammonia decomposition reactor and the fuel cell exhaust.
