The risks associated with transporting electric vehicles (EVs) at sea have been brought into sharp focus by a series of alarming incidents. Notable among these is the fire on the cargo ship Felicity Ace, which highlighted the immense challenge of dealing with lithium-ion battery fires aboard maritime vessels. The ship, carrying approximately 4,000 luxury vehicles including EVs, caught fire in the Atlantic, leading to a prolonged and intense firefighting effort hampered by the nature of the lithium-ion batteries.

This incident, along with others like the fire on the car-carrying vessel Höegh Xiamen in Jacksonville, Florida, underscores the heightened fire risk associated with EVs. These fires are often characterized by their intensity and the difficulty in extinguishing them, primarily due to the phenomenon known as thermal runaway in lithium-ion batteries. Unlike traditional fires, these can be extremely challenging to control and extinguish, often requiring specialized equipment and strategies.

Such incidents not only pose a direct threat to the safety of the crew and the vessel but also lead to significant economic losses. The sinking of the Felicity Ace, for instance, resulted in the loss of a cargo worth hundreds of millions of dollars. Furthermore, these incidents raise serious environmental concerns, as the burning of lithium-ion batteries releases toxic gases and materials into the environment, complicating firefighting efforts and posing additional risks to marine life.

The recurring nature of these incidents has set off alarm bells across the maritime industry, highlighting a pressing need for a reevaluation of safety protocols and emergency response strategies. It has become evident that the conventional methods of maritime firefighting are not fully equipped to handle the unique challenges posed by EVs and their batteries. This realization is driving a much-needed conversation about innovative solutions and proactive measures to mitigate such risks in the future.

The Nature of Lithium-Ion Battery Fires

Understanding the nature of lithium-ion battery fires is crucial for addressing the unique challenges they present in maritime transport. Lithium-ion batteries, which power most electric vehicles (EVs), are prone to a phenomenon known as thermal runaway. This occurs when a battery overheats, leading to a rapid and uncontrollable increase in temperature. Once initiated, thermal runaway can cause a chain reaction, generating intense heat and potentially leading to fires that are notoriously difficult to extinguish.

The complexity of these fires is compounded by the fact that they can reignite even after initial extinguishment. Lithium-ion fires generate extremely high temperatures and can produce noxious and corrosive gases. Traditional firefighting methods, such as using water, are often ineffective and can exacerbate the situation. In some cases, water can react with the burning lithium, intensifying the fire and increasing the risk of explosion. These characteristics make lithium-ion battery fires a formidable challenge on maritime vessels, where space constraints and limited access can hinder firefighting efforts.

Another critical factor in the nature of these fires is their propensity to spread rapidly. In the confined spaces of a cargo ship, especially on car carriers where vehicles are packed closely together, a fire can quickly escalate into a major incident. This risk is heightened in the case of EVs, where a fire in one battery can trigger a domino effect, leading to multiple fires that are hard to control and contain.

The maritime industry's growing awareness of these dangers has led to increased scrutiny of lithium-ion batteries as cargo. The incidents involving vessels like the Felicity Ace serve as stark reminders of the potential consequences of these fires. As a result, there is a pressing need for enhanced safety measures, including improved fire detection systems, specialized firefighting equipment, and rigorous safety protocols to address the unique challenges posed by lithium-ion battery fires at sea.
