The study focuses on the economic viability of hydrogen fuel cell trucks in China's transportation sector, comparing them to electric and diesel trucks. It highlights the importance of analyzing the total cost of ownership (TCO) and includes factors like hydrogen prices, fuel consumption costs, and travel disutility costs. The research indicates that high hydrogen prices have a significant impact on the TCO of fuel cell trucks, making them less competitive in the market. However, the study projects that by 2030, with the expected reduction in hydrogen prices and increased investment in hydrogen refueling infrastructure, the TCO of fuel cell trucks will become comparable to electric and diesel alternatives. This projection is made without factoring in a carbon tax, suggesting a positive outlook for the adoption of hydrogen technology in the transportation sector. Overall, the findings indicate that strategic interventions to reduce hydrogen prices and improve refueling infrastructure could enhance the economic feasibility of hydrogen fuel cell trucks in the near future.
