A zero-emission Kenworth Class 8 T680 day cab tractor equipped with a Ballard hydrogen fuel cell is on display at CES 2018 in Las Vegas. The truck is part of the PACCAR Innovations booth exhibit—the first time PACCAR and Kenworth have exhibited at the show.
The vehicle is part of the Zero Emission Cargo Transport (ZECT) (earlier post) demonstration project managed through Southern California’s South Coast Air Quality Management District (SCAQMD). The truck’s fuel cell produces electricity to power the dual-rotor electric motor or it can recharge the lithium-ion batteries for use later. The hybrid 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.
The hydrogen fuel cell-equipped Kenworth T680 will have an initial range of 150 miles, making it ideal for short haul and port operations. With a dual-rotor traction motor output of 565 horsepower, the truck is capable of carrying the legal gross combination weight of a Class 8 vehicle.
The market is being driven by progressive states, such as California, where clean air is the mandate. To develop the hydrogen-based T680, Kenworth is supported by $2.8 million in funding under a larger grant from the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy, with SCAQMD being the prime applicant. Project oversight is provided by the Center for Transportation and the Environment. Kenworth is also working on a second project under the larger program for DOE and SCAQMD to develop a near-zero emission- capable T680 day cab using a near-zero natural gas engine and generator to extend the battery range.
