The electric truck market is set to witness substantial growth, projected to exceed US$200 billion by 2045. This growth is driven by the increasing adoption of battery electric trucks, plug-in hybrids, and fuel cell trucks. With key regions like Europe, China, and the US leading the transition, governments are implementing emissions standards to accelerate the shift towards zero-emission trucks. For example, the EU and the US have set ambitious targets for reducing emissions from trucks by 2030 and 2032, respectively. Chinese OEMs currently dominate the global electric truck market, with companies like SANY, Dongfeng, and SCMG leading in sales. In Europe, manufacturers such as Volvo and Mercedes are making significant advancements in heavy-duty battery electric trucks. However, challenges persist, including the long duty cycles and high payload requirements of trucks compared to passenger vehicles, as well as concerns about charging infrastructure and total cost of ownership. Fuel cell trucks present a promising alternative to battery electric trucks, offering benefits like lighter weight, faster refueling times, and longer ranges. Manufacturers like Nikola, Hyundai, Toyota, Mercedes, and Volvo are actively exploring fuel cell truck technologies. However, the uptake of fuel cell trucks is hindered by challenges such as sparse hydrogen infrastructure, limited availability of green hydrogen, and total cost of ownership considerations compared to diesel trucks. As the global energy grid transitions towards renewables, the debate between using electricity for battery electric trucks or green hydrogen production intensifies. The future of the electric truck market will depend on addressing these technological, infrastructural, and economic challenges to create a sustainable and efficient transportation sector.
