Ford's H2RV is a Hydrogen engine propelled Hybrid Electric concept Vehicle that was unveiled and driven at Ford's Centennial Show in June 2003. This vehicle is an industry first by an OEM that demonstrates the concept and the marriage of a HEV powertrain with a supercharged Hydrogen ICE that propels the vehicle. Just as Model T was the car of the 20th century, Model U is the vehicle for the 21st century. The powertrain utilizes compressed gaseous hydrogen as fuel, a supercharged 2.3L internal combustion engine, a 25 kW traction motor drive, the electric converterless transmission, regenerative braking, an advanced lithium ion battery, electric power assist steering, electronic throttle and Vehicle System Controller (VSC). The vehicle could deliver a projected fuel economy of 45 mpg and near zero emissions without compromise to performance.

In late 1997 Ford Motor Company Scientific Research Laboratory started the project to design and develop a practical, low-cost hydrogen fueled internal combustion engine (H2ICE) vehicle. This type of vehicle could serve as an interim step to drive the development of the hydrogen infrastructure before the widespread use of fuel cell vehicles. This paper will discuss the design and development approach and results for a dedicated engine optimized for operation on hydrogen, the unique and custom instrumentation necessary when working with hydrogen, the engine dynamometer development program, the unique triple-redundant vehicle safety system, and the final implementation into the Ford P2000 experimental vehicle.

The first known, North American OEM vehicle powered exclusively by a hydrogen fueled internal combustion engine (H2ICE) has been developed and tested. This production viable, low cost, low emission vehicle is viewed as a short term driver for the hydrogen fueling infrastructure ultimately required for fuel cell vehicles. This vehicle features a highly optimized hydrogen IC engine, a triple redundant hydrogen safety system, and a dedicated gaseous hydrogen fuel system. The vehicle and its test results are presented in this paper.
