- Toyota debuted a superconducting pump-equipped hydrogen engine vehicle at the Fuji 24 Hours Race.
- The new system reduces liquid hydrogen boil-off and supports longer vehicle endurance.
Toyota Motor Corporation introduced a major advancement in hydrogen-powered motorsports by participating in the Fuji 24 Hours Race with a hydrogen engine vehicle utilizing superconducting technology for the first time. The race was held at Fuji Speedway in Japan on June 6 and 7. The latest development represents another step in Toyota’s ongoing efforts to improve hydrogen engine performance, efficiency, and practicality through real-world racing conditions while accelerating innovation in next-generation mobility technologies.
The newly developed system takes advantage of superconducting properties that occur at extremely low temperatures of approximately minus 253 degrees Celsius. Under these conditions, electrical resistance becomes effectively zero, enabling more efficient operation of components. Toyota integrated a superconducting pump directly inside the liquid hydrogen tank, a design intended to reduce heat entering the tank and minimize hydrogen boil-off, which occurs when stored liquid hydrogen vaporizes due to temperature increases.

Toyota’s Ongoing Hydrogen Development Journey
Toyota has actively competed with hydrogen engine vehicles since 2021, using motorsport events as a testing ground for emerging technologies. In 2023, the company transitioned from gaseous hydrogen to liquid hydrogen, which offers higher energy density and can store more energy within a given volume. This change enabled greater endurance and improved operational efficiency, helping address some of the challenges associated with hydrogen-powered vehicles.
For the latest race vehicle, Toyota increased the hydrogen tank capacity to 300 liters. The larger tank, combined with the superconducting pump system, was designed to allow the vehicle to complete approximately 40 laps, delivering performance comparable to that of a conventional gasoline-powered race car. The achievement demonstrates the company’s continued focus on enhancing the competitiveness of hydrogen engines in demanding motorsport applications.
Future Development and Research Collaboration
Looking ahead, Toyota plans to collaborate with Kyoto University and the Railway Technical Research Institute to further advance superconducting technology for hydrogen applications. The partners intend to develop a linear-driven superconducting pump aimed at improving durability and operational reliability. These efforts could contribute to more efficient liquid hydrogen handling systems and support the broader adoption of hydrogen-powered technologies across mobility sectors.
The introduction of superconducting technology into a hydrogen engine race vehicle highlights Toyota’s commitment to exploring innovative solutions for sustainable transportation. By combining liquid hydrogen storage with advanced superconducting systems, the company continues to push the boundaries of hydrogen engine development while gathering valuable data from real-world racing environments.
Frequently Asked Questions
What is the purpose of the superconducting pump in Toyota’s hydrogen engine vehicle?
The superconducting pump is designed to reduce heat entering the liquid hydrogen tank and minimize hydrogen boil-off. By operating under superconducting conditions with virtually zero electrical resistance, the pump can function more efficiently while helping maintain the liquid hydrogen state. This improves hydrogen storage performance, supports longer driving endurance, and contributes to the practical development of hydrogen-powered vehicles for future mobility applications and motorsport use.
Why did Toyota increase the hydrogen tank size to 300 liters?
Toyota expanded the liquid hydrogen tank capacity to 300 liters to improve race endurance and achieve performance closer to that of conventional gasoline-powered vehicles. The larger tank, combined with the superconducting pump system, enables the vehicle to complete around 40 laps during racing conditions. This enhancement provides valuable testing opportunities for hydrogen technologies and helps evaluate their potential for broader transportation applications in the future.
