Electric cars are beneficial in terms of reducing CO2 emissions but they do present challenges in terms of tunnel safety.
According to Gunnar Jenssen, a senior researcher at SINTEF, one of the world's leading research institutes in tunnel safety, electric cars are beneficial in terms of reducing pollution but pose a risk due to their batteries. In the event of a collision, the batteries can catch fire, releasing highly toxic gases that are difficult to extinguish. The fire can even reignite several hours after being initially extinguished. Gunnar Jenssen, who has led several major tunnel projects worldwide, emphasizes the potential safety concerns associated with electric vehicles in tunnels.
