You may have seen pictures of the GreenGT H2 from the eco-friendly race car group shots taken at this year’s 24 hours of Le Mans. The H2 is powered by a hydrogen fuel cell that drives two electric motors on the rear axle. It will take the experimental technology spot in Garage 56 (the Nissan Deltawing was in Garage 56 this year) for the 2013 race. This animation shows the layout of the car and how the fuel cells work in conjunction with the car’s air compressors.

*UPDATE* Techologic Vehicles and GreenGT posted another video to show off the sound the H2 makes when the fuel cell is fired up:
