Truckers face challenges of emissions and health risks due to their diesel engines. Range Energy is pioneering the use of electrified trailers to address these issues by improving fuel economy and efficiency. The transportation sector is gradually transitioning to electrification, with the rise of battery-powered vehicles. However, battery-powered trucks face hurdles like high costs, heavy weight, and limited range, although a decrease in ownership cost is projected by 2030. The industry also needs to consider hydrogen as a potential solution for heavy-duty trucks due to its advantages for heavier vehicles with longer distances. While batteries currently outcompete hydrogen in most vehicles, heavy-duty trucks present a unique case where hydrogen might be more suitable. Keeping options open for technology choices is crucial for decarbonizing heavy-duty trucking. Exploring various technologies like batteries and hydrogen can provide the necessary flexibility to find the most effective solutions for a sustainable future.
