ISE Corporation Delivered New England's First Hydrogen Fuel Cell Bus to CTTRANSIT

SAN DIEGO, CA, April 11, 2007 — ISE Corporation, a leading integrator of hybrid-electric and integrated fuel-cell drive systems for buses, has delivered a 40-foot hybrid-electric fuel cell-powered transit bus to CTTRANSIT. This bus becomes New England's first zero-emission fuel cell-powered hybrid bus and will immediately enter CTTRANSIT service. CTTRANSIT is provider of public transit local and express bus services in the Greater Hartford, New Haven, and Stamford Connecticut metro areas.

On hand to witness the quiet fuel cell hybrid bus rolling out onto the streets of Hartford were U.S. Rep. John Larson, D-Conn., and officials from the Federal Transit Administration, Connecticut Department of Transportation, Greater Hartford Transit District, CTTRANSIT, Capitol Region Council of Governments, UTC and ISE.

ISE, with other industry partners, have been working under a $2.9 million grant from the Federal Transit Administration to the Greater Hartford Transit District to develop the Northeast's first hydrogen fuel cell bus. The bus is built on a Van Hool A330 chassis, and the system is powered by UTC Power PureMotion® 120 fuel cell power system.

Under the subcontract agreement, ISE supplied one variant of its fully modular ThunderVolt® hybrid-electric drive system to meet CTTRANSIT's need. In addition to being highly energy efficient, ISE's hybrid-electric drive system requires a smaller fuel cell to power the bus, thus lowering acquisition cost. This advanced hybrid system uses high voltage batteries to recuperate stopping energy that would normally be expended on the brake pads, reducing brake wear and maintenance.

ISE's other industry partner in producing the bus is AC Transit of Oakland, Calif., which now has three fuel cell-powered buses in operation. Another ISE-integrated identical bus, demonstrating hot weather potential, is in full time service at Sunline Transit Agency in Palm Desert, Calif.

"Releasing the 5th bus of its kind, we are building on the accumulated 75,000 miles of its predecessors in a challenging, new environment - the New England winter," said Jayson Cannon, Program Manager. During revenue service, the vehicle is expected to operate in stop-and-go traffic, on highways, and on grades just like any other bus in service. "Laboratory testing and engineering modeling can only take us so far, this is where the rubber meets the road," Mr. Cannon continued. The end product is a vehicle that offers a smooth, quiet ride; all while producing only water out the tailpipe.
