The GreenGT H2 hydrogen race car has been unveiled at the Paul Ricard circuit in France. After years of development, the French constructor was proud to show the world a zero emission vehicle that achieves the performances of a GT car and has an autonomy comparable with race cars powered by an internal combustion engine.
The GreenGT H2 has been equipped with 2 x 160 litre, 350 bar, hydrogen tanks and the 18 stacks fuel cell delivers a linear power of 340kW. It could reach a maximum speed of 300 km/h and it weighs just 1240 kg.
The story began in 2009, when GreenGT first built a prototype battery-electric competition car of 300kW. They found autonomy a problem and therefore they added a 100kW hydrogen fuel cell to provide additional energy. As a result, a more powerful vehicle was soon developed and the company received the invitation to participate in the 2013 24 Hours of Le Mans as ‘Garage 56’ entry. GreenGT withdrawn from the event to further develop the GreenGT H2.
After another two years of work, the vehicle was ready to present to the public. “And following 35 days of tests, our development programme has given the technical team invaluable experience in the dynamic use of a high-powered hydrogen fuel cell,” explained Jean-François Weber, GreenGT’s Managing Director and Head of R&D. “We have focused our work on understanding the complex phenomena linked to this new technology and on building in the consequent technical solutions. By optimizing the components and programs, we have significantly improved the output and reliability of all the GreenGT H2’s systems.”
The development of the GreenGT H2 prototype and its approval have cost about 5 million euros. The firm considers it as a twofold objective: to point the way to the future of the hydrogen electric propulsion and to benefit from the experience for the series production of high power powertrains. They are targeting car manufacturers and petrochemical, gas and electricity distributors as they are in search and development of new technology.
The GreenGT H2 was unveiled by Olivier Panis. The former Formula 1 driver expressed his enthusiasm about cutting-edge technology: “The GreenGT H2 is a magnificent example of hydrogen electric technology that offers power and autonomy. This innovative, clean solution could be used in any vehicle requiring high levels of power: industrial vehicles, buses, trucks, etc. I’m delighted to be part of the adventure, as we’re only at the beginning of a new area and there are major developments still to come.”
GreenGT doesn’t have the intention to race the vehicle, as it considers the GreenGT H2 as a laboratory race car, showcasing the capabilities of the hydrogen electric drivetrain and the company’s expertise on this subject.
