Concerns over fire hazards linked to lithium-ion batteries are reshaping policies in the maritime shipping industry. In a recent move, Alaska Marine Lines (AML) announced that it will suspend the transport of electric vehicles (EVs) and plug-in hybrid vehicles (PHEVs) across most of its routes, citing safety as the key factor behind the decision.
AML, which plays a crucial role in moving cargo between Alaska, Hawaii, and the mainland United States, explained that while incidents with lithium-ion batteries are rare, the consequences can be devastating if they occur at sea. “These fires cannot be easily contained or extinguished, posing risks to both crew and equipment,” the company stated.
The new rule applies immediately to Central and Western Alaska as well as Hawaii, while shipments to Southeast Alaska will only continue until September 1, 2025. The restriction, however, does not extend to conventional hybrid vehicles, e-bikes, or smaller recreational EVs. AML also confirmed it will continue monitoring developments in safety standards to determine if the policy can be revised in the future.
The update is expected to particularly affect Southeast Alaska, where the adoption of EVs has been steadily increasing. Meanwhile, the Alaska Marine Highway System has kept its doors open to limited EV transport, though with strict precautions. Ferries under the system allow no more than two EVs per trip, keeping them in designated spaces and equipping each vessel with specialized fire blankets designed for lithium-ion battery fires.
This move by AML follows similar steps taken by other shipping lines. In June, Matson announced it would no longer carry EVs on its vessels bound for Hawaii and Guam. In Europe, Havila Voyages introduced a comparable ban in 2023, prohibiting EVs and hydrogen-powered vehicles from its coastal fleet.
With multiple carriers tightening rules, the shipping industry is facing growing pressure to balance sustainability goals with maritime safety, particularly as the global demand for electric vehicles continues to rise.
