Material Aspects Pertaining to Hydrogen Production from Aluminum: Opinion

The use of lightweight metals as hydrolyzing materials for hydrogen (H2) generation has attracted much attention in recent years. This is clearly evident when one considers the continuous stream of publications being made available in the public peer-reviewed domain on the subject. Metal-based hydrolyzing materials are combined with water, under certain conditions, to allow the hydrolysis reaction, yielding high-purity H2 on demand. Of the lightweight metals investigated, aluminum (Al) has shown significant potential as it is lightweight, relatively inexpensive, and abundant.
