On 27 June, during the French leg of the FIA WTCC, GreenGT will present the GreenGT H2, a hydrogen fuel cell racing car, on the Paul Ricard circuit. The GreenGT H2, which runs without a battery, achieves the performance of a GT and has a range comparable with competition cars powered by an internal combustion engine, the company says.

Olivier Panis, winner of the Monaco Formula 1 Grand Prix in 1996 and with 158 Formula 1 Grand Prix races to his credit, will unveil the GreenGT H2 on the circuit.
GreenGT first built a prototype electric competition car—the GreenGT 300 kW, 100% powered by lithium/ion batteries—in 2009. As range soon proved to be the feature of the 300 kW with most room for improvement, GreenGT next decided to use a 100 kW hydrogen fuel cell to provide the additional energy needed for the electric motors.
This 100kW fuel cell was then tested and the expected results were confirmed. Based on this work, development of a new chassis and a new more powerful, but far more compact fuel cell (with a linear power of 340 kW or 460 Hp) was started by GreenGT in 2012.
In June 2012, the GreenGT H2 project was selected as an innovative project by the French Automobile Club de l’Ouest (ACO) and invited to participate in the 2013 Le Mans 24 Hours event.
In parallel, a new lightweight twin-engine powertrain, with a power of 400 kW or 540 hp, was developed for the H2 prototype.
The racer that will make its debut on Saturday features the 400 kW stack developed by SymbioFCell for GreenGT. The car is propelled by two 200 kW (400 kW, 544 hp DIN) experimental synchronous three-phase permanent magnet motors, delivering 4000 N·m (2,950 lb-ft) of torque at the rear wheels. Hydrogen is stored at 350 bar in two composite tanks; range is 40 minutes.
