@article{osti_967944, title = {Automotive storage of hydrogen in alane.}, author = {Ahluwalia, R K and Hua, T Q and Peng, J -K and Nuclear Engineering Division}, abstractNote = {Although alane (AlH{sub 3}) has many interesting properties as a hydrogen storage material, it cannot be regenerated on-board a vehicle. One way of overcoming this limitation is to formulate an alane slurry that can be Engineering Hydrogen Storage Systems Energy A five minute or less fill time is desirable. Hydrogen will be supplied as a gas, perhaps at a fixed pressure and temperature. The kinetics of the hydride will dictate how fast hydrogen can be absorbed, and the thermodynamics will determine if hydrogen can be absorbed at all; How to Design Hydrogen Storage Materials? Fundamentals Herein, the latest approaches to design hydrogen storage materials based on known hydrides are reviewed with the aim to facilitate the emergence of alternative thinking toward the design of better hydrogen storage materials. Synthetic methods and conceptual approaches to achieve particular hydrogen thermodynamics and kinetics are discussed.

The number in the product name refers to the quantity of normal liters of gas kept in the vessel (for instance, the MH150 tank can store up to 150NL of hydrogen). Typical uses of the tanks include fuel cell power, gas chromatography and lab experiments/chemical reactions.

Structural Integrity of Composite-Lined Hydrogen Storage

Compared with aluminum-lined hydrogen tanks, composite tanks offer advantages of lightweight and conformability. Real life tank testing is very expensive and time consuming. In this study, a finite element analysis (FEA) tool has been developed to provide a more economical alternative for composite hydrogen tank analysis at operating pressures Thermodynamics of Metal Hydrides:Tailoring Reaction Nov 15, 2010 · While there are plenty of known hydrides with suitable thermodynamics for hydrogen uptake and release at ambient conditions (several bar equilibrium pressure at or nearby room temperature) currently no hydride is known which combines suitable thermodynamics and kinetics with such a high gravimetric storage capacity that a hydrogen storage tank Air in a tank Computational ThermodynamicsAir in a tank¶.
