The processor purifies the hydrogen, compresses it and delivers it to the vehicle's tank.
D/FW will adapt the hydrogen technology for use with the filling station used by airport vehicles that have run on compressed natural gas for several years, Crites said.
The high-pressure hydrogen dispensers, the compressor and storage bottles will look very similar to those at the compressed natural gas fueling station, D/FW officials said.
So far, 581 of the airport's 629 vehicles run on compressed natural gas or propane, according to D/FW energy manager Jerry Dennis. The program has worked well.
D/FW would be the third entity in the United States testing the Ford shuttles.
In February, Ford announced that it would send eight shuttle buses to Florida for passenger and employee transport at Orlando Airport. Delivery is scheduled for 2006, said Sarah Williams, spokeswoman for the Florida Environmental Protection Department.
In May, Ford announced a coalition with an influential American Indian tribe and a clean-cities group in Palm Springs, Calif., for tourist transport between the airport, hotels, downtown, casinos and sightseeing sites.
