The higher pressure means there is more hydrogen volume, which means more autonomy," Granet explained. "While we kept the pressure at 400 bars for the tests, the tanks can hold hydrogen up to 700 bars. During the tests, the car was filled with high-pressure hydrogen at a fueling station developed by TotalEnergies.
HYDROGEN POWERED CARS DRIVERS
The powertrain makes a high-pitched buzz, and Richelmi said drivers can hear more of the car. My role is to tell engineers that, in certain cases, while things may look good on the computers, it may not be good on the track." But as a driver, you get a real feel of the car. "The engineers see many things with data and simulation," he said. Test runsĪccording to Richelmi, his role is to "feel" the car on the track and give this information to the engineers. But a part is fed into the battery, which is used for faster acceleration, such as when a car is exiting a corner. The fuel cell stacks use hydrogen and oxygen to produce electricity, most of which is directly fed into the motor. The H24 is powered purely by electricity. "There is the engine, brakes, acceleration pedal, and steering wheel-but no gearbox, which normally is a big part of a racing car." "It reminded me of my karting days," he said. The 32-year-old from Monaco said driving the car for the first time felt a bit strange. "But it delivered more torque than a petrol engine, and even without pushing too hard, the car easily reached 280 km/hr on the straights." Advertisement "Since it's a new technology and doesn't use either petrol or diesel, I was expecting the car to have low torque and a low top speed," he said. Richelmi, who won the 24-hour race in the LMP2 class in 2016, said he was most impressed with the hydrogen engine's power. One of the drivers who tested the H24 during the weekend was Stéphane Richelmi, a past winner at Le Mans. "The data from these tests help us to understand and improve the car's performance, which forms the basis of creating the regulations for the new category," he said. It ran some tests at Le Mans on the days leading up to this year's race and did a demonstration lap of the 13.6 km (8.5 mile) circuit just before the start on Saturday afternoon. The H24 car, the latest of the two prototypes, is being tested at different circuits across Europe.
"In partnership with ACO, we are helping define the sporting and technical regulations for the new category," Granet said. GreenGT is developing the hydrogen fuel cell powertrain for these cars, which will be designed around a chassis built by Oreca and Red Bull Technologies. The company's forerunners were stationed in that tent. He appeared particularly thrilled because, on the eve of the start of this year's race, the ACO (Automobile Club de l'Ouest), which organizes the 24 Hours of Le Mans, announced a new category of race cars at the Le Mans event for 2025: hydrogen-electric prototypes. One of those people was François Granet of the Franco-Swiss company GreenGT. Every now and then, people wearing blue T-shirts bearing the logo of "Mission H24" would walk by the cars to attend meetings in a motor home sitting next to the tent.
