Presented here is a novel system that uses an aluminum- based fuel to continuously produce electrical power at the kW scale via a hydrogen fuel cell. This fuel has an energy den- sity of 23.3 kWh/L and can be produced from abundant scrap aluminum via a minimal surface treatment of gallium and in- dium.
Such tuning can be used to meet demands for brief bursts of hydrogen, for example, or for lower, longer-lasting flows. The work confirms that, when combined with water, aluminum can provide a high-energy-density, easily transportable, flexible source of hydrogen to serve as a carbon-free replacement for fossil fuels.
According to a life cycle assessment (LCA) conducted by Hiraki et al. considering both the processes of the required deionized water production and residue treatment, the energy requirement of aluminum-based hydrogen production is only 2% and its carbon dioxide emission is 4% of conventional production methods.
This becomes a barrier if the aluminum battery is intended to be electrically rechargeable. 100 Ultimately, the abundance, structural integrity, and ability to form intermetallic phases of aluminum make it a compelling candidate for battery applications despite challenges such as oxidation and oxide layer formation.
