Truck manufacturers are under pressure to reduce emissions from heavy-duty vehicles, which account for a significant portion of transport emissions in Europe. The options for zero-emission vehicles are electric motors powered by either batteries or hydrogen fuel cells. While batteries have been more widely adopted for passenger vehicles due to lower costs, the challenges for trucks, such as range and load capacity, have led manufacturers to consider hydrogen fuel cells. Advancements in battery technology, including cost reduction, increased energy density, and faster charging times, have made battery-powered trucks more feasible. On the other hand, hydrogen fuel cell trucks offer advantages in carrying heavy loads and quick refueling but currently emit more and are less cost-efficient than battery-powered trucks. Despite the advantages of batteries, some manufacturers like Daimler and Volvo are also investing in hydrogen trucks for specific applications. The future of clean truck technologies is projected to be dominated by battery-powered trucks, with fuel cell trucks expected to have a limited market share by 2050.
