Bizarre Batmobile look on this hydrogen fuel cell technology demonstrator. Unfortunately it has been withdrawn from the 2013 event and the following statement has been issued:
The Green GT H2 has been withdrawn from Le Mans as it is not ready to compete. Whilst testing of the car started a few weeks ago the team has decided that it would lack the required reliability “The GreenGT H2 is already showing great potential and has great scope for improvement. However, the complexity and cost of this unique model requires the use of extremely rigorous methods and very time-consuming new procedures” explained Jean-François Weber, Managing Director and Head of R&D of GreenGT. “We are only at the beginning of this adventure, and it is essential for us not to cut corners and continue the development of that highly effective demonstration of hydrogen technology which is the GreenGT H2″.
The car will be used in demonstration runs later in the season.
Innovations developed for the GreenGT H2 prototype:
1. Powertrain with a differential torque function (patent pending).
2. Powertrain incorporating a twin engine and electric converters.
3. Specific lubrication for an electric gearbox designed for low operating temperatures (patent pending).
4. Centralized control of electronics and high power currents.
5. Fuel cell: air loop without humidifier.
6. Piloting of the fuel cell air supply by electric turbochargers.
7. Integration of the hydrogen supply system, including pressure reduction, filling, thermal and mechanical safety functions; retractable with its removable hydrogen tank.
8. Thermal control of the fuel cell.
9. Operating mode and control algorithms for power of engine and fuel cell without a buffer battery.
10. Specific instrumentation and dashboard for electric vehicles.
11. Analysis of failure modes and development of safety countermeasures for electric vehicles.
12. Separate control of electricity supply for power and command functions.
13. Safe integration of electric power components.
14. Wiring, switches and connectors specific to high power electric vehicles (> 400A and 400V).
15. Safe Kevlar-Nomex housing for electric power components: protection of occupants and service personnel.
