![]() The electrical energy can power the dual-rotor electric motor to move the truck, or recharge the lithium-ion batteries for use later. 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. 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. The truck has a 30-mile zero emissions range using electricity stored in the onboard lithium-ion batteries. The T680 HECT tractor, which made 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. ![]() Both the T680 HECT and T680 ZECT projects are funded in part by the Office of Energy Efficiency and Renewable Energy (EERE), the US Department of Energy, and the South Coast Air Quality Management District. The first T680 is called HECT (Hybrid Electric Cargo Transport), and the second T680 is ZECT (Zero Emission Cargo Transport). Leading the way were two special Kenworth T680 day cabs. ATTENDEES at the Advanced Clean Transportation (ACT) Expo saw Kenworth trucks incorporating the latest green emission technologies designed to help fleets and truck operators address requirements for emission reduction.
