Rechargeable aluminum ion batteries (AIBs) hold great potential for large-scale energy storage, leveraging the abundant Al reserves on the Earth, its high theoretical capacity, and the favorable redox potential of Al 3+ /Al.
To this regard, this study focuses on the use of aluminum as energy storage and carrier medium, offering high volumetric energy density (23.5 kWh L −1 ), ease to transport and stock (e.g., as ingots), and is neither toxic nor dangerous when stored. In addition, mature production and recycling technologies exist for aluminum.
Extremely important is also the exploitation of aluminum as energy storage and carrier medium directly in primary batteries, which would result in even higher energy efficiencies. In addition, the stored metal could be integrated in district heating and cooling, using, e.g., water–ammonia heat pumps.

Aluminum has a high specific energy ( ≈ 31 MJ/kg), is safe and easy to store and transport, has a low risk of premature or accidental oxidation if particles are coarse enough, and can be recycled indefinitely. When aluminum oxide is reduced to aluminum, the energy state of the material increases.
Aluminum redox batteries represent a distinct category of energy storage systems relying on redox (reduction-oxidation) reactions to store and release electrical energy. Their distinguishing feature lies in the fact that these redox reactions take place directly within the electrolyte solution, encompassing the entire electrochemical cell.
Aluminum is well suited to play the role of “X” in a power-to-X system. Aluminum possesses the characteristics that are most important for a sustainable energy carrier: high energy density, abundance, recyclability, and it is anticipated that the alumina-reduction process will soon be free of carbon emissions.
