"We’re certainly seeing a huge push around decarbonisation,

and the car industry has led in the development of battery technology and alternative fuel vehicles for this purpose" (McLoughlin, 2022)

The year 2021 witnessed a remarkable surge in Electric Vehicle (EV) sales across major automotive markets, including China, the US, and Europe. Notably, sales in the first half of the year spiked by an impressive 160%, totaling 2.6 million units. This surge accounted for 26% of new sales in the global automotive market. Within Europe, the Nordic countries, particularly Norway, stand out as leaders in this electric revolution (, 2023)

As the number of electric vehicles on the road continues to grow, an uptick in their involvement in traffic incidents is foreseeable due to their increasing presence. Additionally, the potential for battery cells to unexpectedly ignite or explode during charging poses a concerning environmental and safety threat to their surroundings.

In recent years global electric vehicle (EV) movement is gaining remarkable traction around the world. For example, in the UK alone, statistics from the Department for Transport and the Office for Zero Emission Vehicles put forth that the number of EV registrations in the north of England has doubled to 74,677 since 2021 (, 2022). This surge is a testament to the government's efforts to usher in a cleaner and more affordable era of transportation, resulting in the creation of tens of thousands of green jobs across the nation. Nationally, plug-in vehicle sales have skyrocketed by over 70%, with a record-breaking 327,000 plug-in vehicles registered in 2021, marking a substantial 77% surge compared to the previous year (, 2022).

As the UK's transport revolution unfolds, it underscores a commitment to robust infrastructure, efficient transport networks, and economic growth across regions. The government's Electric Vehicle Infrastructure Strategy, backed by a substantial £1.6 billion funding, seeks to amplify on-street EV charging capabilities by a factor of ten, thus alleviating the common concern of 'range anxiety' while promoting wider EV adoption. By 2030, the UK aims to establish 300,000 public electric vehicle chargepoints—equivalent to almost five times the current number of fuel pumps on the roads. This impressive progress is supported by the installation of around 600 new public chargepoints each month, underscoring the UK's leadership in the global shift to electric vehicles (, 2022).

Moreover, this transition is more than just a shift in transportation; it's a catalyst for positive change. The push towards emission-free travel has yielded up to 40,000 new automotive jobs and a substantial 11% reduction in average carbon dioxide emissions for cars, indicating a cleaner and healthier environment. With a commitment to phasing out new petrol and diesel cars and vans by 2030, the UK is driving toward a net-zero transport future, ensuring all drivers can access EVs with their lower operational costs. This transformative journey, reinforced by substantial investments and industry support, is cementing the UK's role as a leading hub for the design, manufacturing, and utilization of zero-emission vehicles, cultivating economic growth, employment, and environmental sustainability (, 2022).

Understanding Electrical Vehicle Fire Risks

As evident with their sustainable and green capabilities as seen within the UK, electric vehicles bring numerous benefits to both indivduals in terms of jobs, and societies as a whole, but, they also come with specific safety concerns related to their high-voltage battery systems. This is because electric vehicles predominantly rely on rechargeable lithium-ion batteries as their primary power source (Tesla, 2006). These batteries, initially developed in the 1990s, found their first application in powering cars during the early 2000s. In contrast, traditional petrol and diesel vehicles have a history spanning well over a century 'with transportation fuel for humans began in 1858' (, providing a much longer time-frame for accumulating safety-related data and insights.

While electric vehicles are inherently designed with a high level of safety, one of the primary concerns arises when dealing with potential damage to the lithium-ion battery. Such damage can occur if the battery is exposed to extreme heat or if an object punctures the protective barrier of a battery cell. 

In essence, electric vehicles are built with safety as a fundamental principle. However, due to the relative recency of their introduction compared to traditional vehicles, there is still a need to gather and comprehend extensive data about their long-term safety performance. The critical point of concern remains the condition of the lithium-ion battery, which demands careful handling to prevent scenarios involving extreme temperatures or physical breaches to the battery's integrity.

Factors contributing to EV fire risks include thermal runaway, short circuits, and external factors like collisions. For example, in the case of lithium-ion batteries, commonly used in EVs, are susceptible to thermal runaway, a condition in which the battery heats up uncontrollably, potentially leading to fires and explosions.

An EV fire is also harder to extinguish and may re-ignite. Re-ignition of the battery occurs when other nearby cells within the battery pack become damaged in the initial incident and go into thermal runaway sometime after.

Thermal Runway: An Electical Vehicle Fire Phenomenon?

Thermal Runway ProcessThermal Runway Process
Thermal Runway Process

Thermal Runaway is an occurrence of a series of self-sustaining heat-releasing reactions within the battery, caused by high temperatures or voltage trigger chemical reactions within a battery cell. These reactions overpower the battery's cooling mechanisms, leading to ignition. If ignition occurs, nearby battery cells might also undergo thermal runaway. As a result, the likelihood of fire increases with the number of cells experiencing this runaway, potentially causing the entire battery to fail.

Remarkably, thermal runaway can transpire even at relatively low temperatures (Kong et al. 2023) and at low pressures (Xie et al. 2020). In such cases, battery failure may involve the release of flammable gases and an increased amount of gas release (Jia et al. 2022) In fact, the process generates around 100 organic chemicals, including highly toxic gases (Held et al. 2022) like carbon monoxide and hydrogen cyanide. These gases can ignite if an ignition source is present or if the environment provides conditions suitable for combustion, such as ample oxygen, a fuel source, and heat. 

This inherent risk is magnified in emergency situations like ship fires, especially if electrical vehicles are on-board being transported within an enclosed area like a car park or cargo holding, as North of England P&I Club’s Director of Loss Prevention, Colin Gillespie states in an article about safe carriage aboard vessels that they are examining ships that were not initially constructed to accommodate electric vehicles and other types of alternative-fueled vehicles. It's possible that the crew may not possess the training needed to identify or appropriately manage such fire scenarios (, 2022)

In short, addressing these challenges is crucial as we navigate towards safer and more sustainable transportation options in relation to electrical vehicles within maritime enviroments.

EV Fires & Maritime Enviroments

In maritime contexts, the potential for EV fires poses unique challenges due to the confinement of space and limited means of escape. When a ship fire occurs, the combination of an enclosed environment, the presence of multiple electric vehicles with lithium-ion batteries, and the proximity of these vehicles to each other can create conditions conducive to a quick spread of fire. The confined space restricts the dissipation of heat and gases, potentially intensifying the severity of the fire.

Furthermore, the nature of ship fires often involves a complex interplay of factors such as restricted accessibility, limited firefighting resources, and the need to manage the safety of both crew members and passengers. If an EV fire ignites within a confined space like a cargo hold or car park area on a ship, the potential for thermal runaway to spread to neighboring battery cells and vehicles could escalate the situation.

Addressing this challenge requires specialised strategies and technologies tailored to maritime settings. Innovative fire safety solutions and EV fire safety equipment, like the Fire Isolator system, which can rapidly disconnect high-voltage battery systems and contain thermal runaway, play a crucial role in preventing the escalation of EV fires in such confined spaces. The emphasis on collaboration between ship operators, manufacturers, regulatory bodies, and fire safety experts becomes paramount to ensure effective strategies are in place to mitigate the risks associated with EV fires in maritime emergencies.

Mitigating Electrical Vehicle Fire Risks - A Case Study from Netherlands Cargo Ship Incident

As mentioned earlier, lithium-ion batteries, commonly used in EVs, are susceptible to thermal runaway—a condition in which the battery undergoes uncontrolled heating, potentially leading to fires and explosions. This risk is significantly heightened in critical situations like ship fires, particularly within maritime environments where both the ship and the staff may be ill-prepared for the consequences of an electrical fire incident.

Which brings us to our case study.

A cargo ship named the "Freemantle Highway" experienced a catastrophic fire in the North Sea. Among the cargo electrical vehicles with a lithium-ion battery that contributed to the fire's intensity. Out of the total 3,783 vehicles aboard the Freemantle Highway, it has been stated that electric vehicles (EVs) accounted for approximately 13.2%, with a count of 498 units of EVs on-board during the time of the incident (, 2023). 

The fire erupted off the coast of the Netherlands, prompting the complete evacuation of the crew and tragically resulting in the loss of one seafarer's life.

Although there exists claims that the fire itself was not caused by an electrical vehicle fault, the fact remains that having such a concentrated number of EVs on-board likely contributed to the catastrophy. And in support of this, there have been unoffical / leaked images from the burned cargo Evs seen at the site of the incident — including cars which are fully electric.

As a whole, this further underscores the paramount importance of possessing the right safety equipment to combat electrical fires, coupled with comprehensive EV fire training to ensure EV fire control, and  allowing effective prevention and turn, elimination of future electrical fire incidents aboard large vessels and transport ships that are carrying electrical vehicles, or cargo at risk of electrical fires.
