Kenworth trucks incorporating the latest green emission technologies designed to help fleets and truck operators address requirements for emission reduction have been on display this week at Advanced Clean Transportation (ACT) Expo in Long Beach, California. Two special Kenworth T680 day cabs, the HECT (Hybrid Electric Cargo Transport) and the ZECT (Zero Emission Cargo Transport) attracted plenty of interest.

Both the T680 HECT and T680 ZECT projects are funded in part by the Office of Energy Efficiency and Renewable Energy (EERE), the U.S. Department of Energy and the South Coast Air Quality Management District.

Kenworth T680 Hybrid Electric Cargo Transport (HECT)

The T680 HECT tractor, which is making its public debut at ACT Expo, incorporates a parallel hybrid electric propulsion system that uses the Cummins Westport ISL G Near Zero (NZ) emission engine fueled by compressed natural gas (CNG), in combination with a generator to extend the truck’s battery range. The truck has a 30-mile zero emissions range using electricity stored in the onboard lithium-ion batteries. When the batteries are depleted, the near-zero emission engine turns on to generate more energy and extend the truck’s range up to 250 miles.

Kenworth T680 Zero Emission Cargo Transport (ZECT)

The T680 ZECT tractor, which debuted at the Consumer Electronics Show (CES) earlier this year, uses a hydrogen fuel cell that combines compressed hydrogen gas and air to produce electricity, with only water vapor emitted at the exhaust pipe. The electrical energy can power the dual-rotor electric motor to move the truck, or recharge the lithium-ion batteries for use later. The electric drive system manages the power from the fuel cell to and from the batteries, as well as the traction motors and other components, such as the electrified power steering and brake air compressor.

Both technologies are in development and testing, with field trials to begin scheduled to begin later this year with Total Transportation Services Inc. (TTSI) at the Ports of Los Angeles and Long Beach.
