“…Additional work is needed and encouraged to determine whether Ni additives may be the key to making H 2 more accessible in NaBH 4 . [39]. The decomposition temperature was measured by TGA heating from ambient to 300 °C with a heating rate of 5 °C/min under a nitrogen gas flow rate of 50 mL/min.…”

Hydrogen (H 2 ) shows great promise as zero-carbon emission fuel, but there are several challenges to overcome in regards to storage and transportation to make it a more universal energy solution. Gaseous hydrogen requires high pressures and large volume tanks while storage of liquid hydrogen requires cryogenic temperatures; neither option is ideal due to cost and the hazards involved. Storage in the solid state presents an attractive alternative, and can meet the U.S. Department of Energy (DOE) constraints to find materials containing > 7 % H 2 (gravimetric weight) with a maximum H 2 release under 125 °C. While there are many candidate hydrogen storage materials, the vast majority are metal hydrides. Of the hydrides, this review focuses solely on sodium borohydride (NaBH 4 ), which is often not covered in other hydride reviews. However, as it contains 10.6% (by weight) H 2 that can release at 133 ± 3 JK −1 mol −1 , this inexpensive material has received renewed attention.

“…Nevertheless, the efficiency and safety of storage remain what restricts the widespread applications of hydrogen. Up until now, there have been plenty of efforts made to demonstrate the potential of NaBH 4 as a promising material used for hydrogen storage 10‐14 .

Summary An investigation was conducted into the generation of hydrogen from catalytic hydrolysis of alkaline sodium borohydride solution in a micro‐scale fluidized bed. In this work, the Cobalt loaded on walnut shell activated carbon was applied as the catalyst. The impact of NaBH4 concentration, the diameter of catalyst particle, the rate of reaction fluid flow, and the temperature of initial reaction fluid on the process of hydrogen generation was explored, and the optimum reaction conditions were determined. It was found out that the maximum length of stable hydrogen generation (58.46% of the total reaction time) is obtainable under the following conditions. The concentration of NaBH4 is 2 wt%, the flow rate is 3.00 × 10−3 m·s−1, and the flow temperature is 25°C. In addition, a comparison was performed between the batch reactor and micro‐fluidized bed reactor during the process of hydrogen generation. Moreover, when the concentration of NaBH4 reached 1 and 2 wt%, the efficiency and stability of the micro‐fluidized bed reactor were identified as superior to those of the batch reactor.
