Abstract Scope Decarbonization of the shipping industry along with other long-haul transportation is of the toughest and most important challenges to resolve toward greenhouse emission elimination. A molten salt magnesium-air battery shows promise toward meeting this challenge. This work presents the improvement achieved in long-run battery performance through solidifying the MgO reaction product from the molten salt electrolyte by using a cold finger. Moreover, preliminary result on Mg reduction at the battery anode is discussed which leads to the recharging of these batteries. Finally, a battery design in a 20-foot shipping container could deliver 60-90 MWh of energy, which is 20-30 times the energy of containerized lithium-ion batteries, at a fraction of the cost. Disadvantages include the inability to scale down due to high-temperature operation, and lower round-trip efficiency than Li-ion batteries.
