"APS is a logical partner for ECOtality to further our promotion of clean technologies," said Jonathan Read, CEO, ECOtality. "By working with APS, we are able to educate the public and demonstrate that hydrogen is a viable alternative fuel that produces zero emissions."

As part of the relationship, APS will provide services, educational materials and hydrogen fuel for the ECObus at its Hydrogen Park in downtown Phoenix. The APS Hydrogen Park was constructed in 1920 for the production of gas for the city of Phoenix to illuminate its street lights. The transformation of the facility, completed in 2002, currently supplies hydrogen compressed and natural gas or a combination of both to vehicles that operate on such fuels.

"APS is committed to supporting natural and clean energy development for the state of Arizona. In addition, this partnership presents a good opportunity to further educate students and the public about renewable energy," said Peter Johnston, manager, technology development, APS.

The ECObus, a mobile learning center, will serve as a symbol for hydrogen education and to educate the public on clean technologies and will tour the state for three months. The ECObus will be launched on Tuesday, February 27 in conjunction with Arizona's Clean Cities Coalition event. For more information about the ECObus, visit www.ecotality.com.
