Toyota is taking another step in the development of hydrogen technologies. During the "24 Hours of Le Mans" marathon, the company will for the first time conduct public runs of the TR LH2 Racing Prototype, which uses liquid hydrogen as fuel. The demonstration laps will take place on the legendary Circuit de la Sarthe on June 11 and 13.
The new car is built on the chassis of the TR010 HYBRID racing hypercar, which competes in the WEC World Endurance Championship. However, instead of a traditional hybrid powertrain, it uses an internal combustion engine adapted to run on hydrogen. The main goal of the project is to test the prospects of this technology in the extreme conditions of motorsport.
The use of liquid hydrogen is of particular interest. Compared to gaseous hydrogen, it has a higher energy storage density, which is especially important for racing vehicles where every kilogram and every liter of volume matters. At the same time, such a system requires complex cryogenic infrastructure and fuel storage at ultra-low temperatures.
For Toyota, this project is a continuation of a long-term program for the development of hydrogen engines. The company began testing similar technologies in the Japanese Super Taikyu series based on a hydrogen Toyota Corolla, initially using gaseous hydrogen, and then switching to liquid. Now, the developments are being transferred to a much more high-tech class of racing cars.
While the TR LH2 remains an experimental project, its appearance at Le Mans shows that the struggle for a carbon-neutral automotive future is not limited to batteries alone. In the coming years, racing tracks may determine which alternative powertrains will have a chance for mass adoption.
