“…It is generally made in small batches and used for organic transformation. Aluminum hydrides have excellent potential to be a part of the solution to hydrogen storage and remain a key topic of research, as AlH 3 specifically but also a promising component of more complex systems [30][31][32][33][34].…”

There are clear advantages to using hydrogen as a fuel, but storage of hydrogen in a light-weight and compact form remains a challenge. This review highlights past breakthroughs that led to the current thinking in hydrogen storage methodology. Metal organic frameworks are discussed briefly, with greater attention to the storage of hydrogen in other molecules. Many molecular storage strategies rely on the thermal decomposition of hydrogen hetero atom bonds and formation of hydrogen to hydrogen bonds. An acid-base thought model is presented to explain observed behaviors and to guide future endeavors.

The Hydrogen Storage Engineering Center of Excellence is a team of universities, industrial corporations, and federal laboratories with the mandate to develop lower-pressure, materials-based, hydrogen storage systems for hydrogen fuel cell light-duty vehicles. Although not engaged in the development of new hydrogen storage materials themselves, it is an engineering center that addresses engineering challenges associated with the currently available hydrogen storage materials. Three material-based approaches to hydrogen storage are being researched: 1) chemical hydrogen storage materials 2) cryo-adsorbents, and 3) metal hydrides. The U.S. Department of Energy through its USDRIVE program has established storage system targets to ensure that light-duty vehicles using these technologies have driving ranges comparable to currently available vehicles while meeting commercial performance, cost, and reliability requirements. Specific target values are provided for specific years to help guide the system development. The targets include gravimetric and volumetric density, cost, operating temperatures and pressures, charging and discharging rates, transient behavior, and safety. As a member of this Center, Pacific Northwest National Laboratory (PNNL) has been involved in the design and evaluation of systems developed with each of these three hydrogen storage materials. The scope of PNNL's efforts in the development of chemical hydrogen storage materials includes the following five major tasks as delineated below:  Develop storage system designs that are amenable to vehicle applications. The goal of these storage systems is to meet the DOE Technical Targets for light-duty vehicles.  Collect the key properties of the storage materials that are required to develop these system designs. Such things as thermodynamic characteristics, reaction kinetics, and transport properties were measured.  Develop models that predict the system's performance in a vehicle and allow the storage system to be appropriately sized to meet a set of drive cycles.  Perform experimental work to guide the system design of individual components and ultimately validate the storage system models.  Develop system costs for production ranges between 10,000 and 500,000 units for the most viable systems developed. The cost estimates were developed using both top-down and a bottom-up approaches. Work on chemical hydrogen storage materials was performed in both Phase I and Phase II. DOE determined not to continue work with chemical hydrogen storage materials in Phase III. The PNNL Phase-I work focused on the development of a storage system using solid ammonia borane as the storage material in the form of a powder or pellet. The PNNL Phase-II work focused on development of a chemical hydrogen storage material using slurry material. Rather than focusing only on slurry forms of ammonia borane, it included the evaluation of a slurry form of alane as well. Both phases included development of system designs, measurements of key properties, model development, vali...

“…In fact, few thermochemical properties are known for any aluminum containing molecules, alanes in particular. Aluminates such as aluminum hydride are important because they are commonly used as reducing agents and have been proposed as a means for hydrogen storage [7]. In this study, we determined the fluoride affinities of fluorinated alanes using a flowing afterglow-triple quadrupole instrument.…”
