Dual hydrogen and suspension production system using magnesium-aluminum based effervescent tablets

A system and method for producing hydrogen (H2) gas and a magnesium (Mg)-aluminum (Al) based aqueous suspension from pre-prepared effervescent tablets are provided. The produced H2 gas can be stored in a tank or directly utilized in a fuel cell, whereas the produced suspension can be employed as an advanced heat transfer fluid in a variety of thermal applications. Furthermore, the as-prepared tablets are fabricated with a homogeneously mixed and well-compressed mixture of Al particles, Mg particles, and sodium bicarbonate (NaHCO3) powder in a sealed container to prevent air and humidity from reacting with the raw materials. As a result of the chemical reaction between the tablet and water, H2 gas (in the form of bubbles) and the Mg—Al-based suspension are produced simultaneously. This system results in two products (i.e., H2 and suspension) that can be used individually or all at once by integrating the different system components together.
