In the quest for carbon neutrality, hydrogen-powered vehicles are gaining traction, but high costs and durability issues have slowed their widespread adoption. A recent study published in the *International Journal of Electric and Hybrid Vehicles* offers a fresh perspective on the techno-economics of hydrogen hybrid vehicles, comparing hydrogen fuel cell vehicles (H-FCVs) with hydrogen internal combustion engine hybrid electric vehicles (H-HEVs). Led by Dapai Shi of the Hubei Key Laboratory of Power System Design and Test for Electrical Vehicle at Hubei University of Arts and Science, the research provides valuable insights into the future of hydrogen-powered transportation.
The study highlights the challenges faced by H-FCVs, particularly their high total cost of ownership (TCO) and limited durability. “H-FCVs are more expensive and less durable than H-HEVs, which hinders their large-scale deployment,” Shi explains. To address these issues, the research team developed a multi-objective powertrain parameter optimization model, evaluating TCO from vehicle purchase to disposal and optimizing hydrogen consumption using a global dynamic programming method.
The findings reveal that while H-FCVs can achieve optimal fuel economy and hydrogen consumption with a battery capacity of 20.5 Ah and an H-FC peak power of 55 kW, their TCO remains higher than that of H-HEVs. “H-FCVs can only become cost-competitive if the unit power price of the fuel cell system is less than 4.6 times that of the hydrogen engine system, assuming negligible fuel cell degradation,” Shi notes. This suggests that, in the short term, H-HEVs should be prioritized.
The study also emphasizes the complementary relationship between H-FCVs and H-HEVs. “The adoption of H-HEVs can support the long-term development of H-FCVs,” Shi says. This synergy could pave the way for a more sustainable and economically viable hydrogen-powered transportation sector.
The research has significant implications for the energy sector, particularly in shaping future developments in hydrogen hybrid vehicles. As the world moves towards carbon neutrality, understanding the techno-economics of these vehicles is crucial for stakeholders in the energy industry. The study’s findings could influence policy decisions, investment strategies, and technological advancements, ultimately driving the transition to a low-carbon future.
In conclusion, this research offers a comprehensive comparison of H-FCVs and H-HEVs, providing valuable insights into their techno-economics. As the energy sector continues to evolve, the findings of this study will be instrumental in shaping the future of hydrogen-powered transportation.
