The Al-Air battery is an attractive candidate as a power source for electric vessels due to its higher energy density, significantly greater than that of a Lithium-Ion battery. The result of this higher energy density is that an Al-Air stores more energy with much lower weight and volume than Li-Ion. Furthermore, since it cannot be recharged electrically (which would be arguably difficult while at sea) but mechanically, this results in another sensational improvement: by swapping the Aluminium anode (easily and quickly, like a printer cartridge) the boat user can extend its autonomy and thus remove the range anxiety typical of Li-Ion-powered vehicles.
- Marine engines have very high fuel consumption and are highly polluting
- Fisheries account for about 1.2% of global oil consumption, about 50 billion litres of fuel, totally unaddressed yet by viable and affordable green maritime mobility solutions
- About 86 percent of the 4 millions motorized fishing vessels in the world are smaller than 12 meters or 15 Gross Tons, the ideal size for Aluminum-Air batteries
- There are 15 million Recreational Boats in the world seeking a green solution for their propulsion
Standby Power Application
Al–Air batteries hold great promise also for large standby energy applications due to their low cost, high specific capacity an indefinite durability when not in use. Since there is no limitation to the quantity of batteries that can be kept connected, they can be employed in those cases when the loss of power results in a significant reduction in productivity or financial loss.
