TOYOTA
Toyota has announced that it will take part in the Super Taikyu Championship 24-Hour Endurance Race, which will be held from May 26 to 28 at the Fuji Circuit in Japan. The Japanese company will run with the GR Corolla H2 Concept, that is the racing GR Corolla that consumes liquid hydrogen, being the first in the world. In addition, this will be the first time a liquid hydrogen vehicle will run in an endurance race.
As of May 2021, Toyota is competing with a similar hydrogen-powered GR Corolla H2 Concept in Japan, but using hydrogen in gaseous form. The switch to liquid hydrogen is a big step forward in evolution, making the car more competitive.
Liquid hydrogen also makes pitstops faster and more efficient, as refueling can be done in the same space as petrol-powered vehicles. By using liquid hydrogen as a fuel, the equipment previously necessary to produce compressed hydrogen gas—such as compressors and precoolers to cool the hydrogen—is no longer needed.
As a result, the area required to install the station can be four times smaller compared to hydrogen gas stations. In addition, since there is no longer the need to pressurize during filling, many vehicles can fill their hydrogen tanks sequentially.
Over the past two months, the weight of the racing GR Corolla H2 Concept has been reduced by more than 50 kg, resulting in better times than the hydrogen-powered GR Corolla when it debuted in May 2021, with hydrogen in gaseous form. However, the challenges with liquid hydrogen are that it must be kept at temperatures below -253 degrees Celsius and the fuel pump must operate at these temperatures while preventing the hydrogen from vaporizing due to heat in the tank.
