Postal Service Tests New Hydrogen Fuel Cell Vehicle

Rain, sleet and snow won't stop the nation's mail carriers, but rising gas prices could slow them down. The U.S. Postal Service estimates every 1-cent increase in the price of a gallon of gasoline drives up annual fleet operating costs by $8 million. In 2007, the fuel bill was $1.7 billion; this year it's expected to grow another $600 million.
Not surprising, the agency that operates vehicles in every community in America was more than happy in July to accept a Chevrolet Equinox fuel cell electric vehicle from General Motors. The company's latest version of a hydrogen vehicle requires no petroleum-based fuel.
In an agreement with General Motors, the Postal Service is participating in a two-year test of the fourth-generation electric vehicle in Irvine, Calif. With a fleet of 220,000 vehicles across the country, the Postal Service is in a good position to help drive the hydrogen market, if the vehicles eventually become commercially viable, said Richard Maher, a USPS spokesman in Irvine.
"It's not like any other vehicle," said Maher, who has driven it. "It's totally silent. The acceleration is very smooth and it builds up to a good speed pretty quickly, but you can't hear it."
The ultra-quiet vehicle is a little disquieting for most drivers initially, because they wonder if it's actually running, he said.
"The carriers like it a lot. It's very comfortable," Maher said. The Postal Service tested General Motors' previous prototype, which was smaller and even quieter than the current Equinox. That version wasn't as practical because space for mail was more limited and pedestrians would often be startled when the vehicle moved because they didn't realize it was running. The new version, while quiet inside, generates enough noise outside to reduce the startle factor for pedestrians, Maher said.
Roz Sell, commercial program manager for General Motors fuel cell commercialization office, says the Postal Service offers an ideal setting for testing. The agency is using the vehicle for regular mail delivery six days a week with lots of starts and stops. "That's an excellent duty cycle for us to understand," said Sell.
