Kenworth’s rendering of a T680 equipped with a hydrogen fuel cell.More fuel cell truck news from ACT Expo this week as Kenworth announced plans to put a zero emission T680 drayage truck to work at the nation’s largest ports.
That truck will be joined by a hybrid T680 powered by a Cummins Westport ISL G Near Zero NOx engine fueled by compressed natural gas (CNG). Both trucks, which are backed by $9 million in government grants, will begin hauling freight later this year at the Ports of Los Angeles and Long Beach.
“These T680 day cab projects provide an excellent opportunity for Kenworth to develop and advance important technologies that may play a critical role in the trucks of tomorrow,” said Patrick Dean, Kenworth chief engineer. “Within the next decade, hybrid-electric powertrains are expected to be required to satisfy emissions regulations in several major U.S. metropolitan areas. For example, California is considering regulations that will require zero-emission levels for port drayage trucks operating in specifically designated areas. We look forward to playing a leadership role to meet the opportunities and challenges ahead.”
Kenworth is developing a prototype Class 8 hydrogen fuel cell tractor designed to provide zero-emissions operation. Built by Ballard Power Systems in Burnaby, British Columbia, as the fuel cell works to recharge the batteries, the only emission coming out of the tailpipe will be water.
Lithium-ion batteries will power a dual-rotor electric motor, driving the rear tandem axle through a 4-speed automated transmission. Kenworth’s hydrogen truck is expected to be ready for initial track and on-road testing in the fourth quarter of this year.
This week, Kenworth began building a second prototype series hybrid-electric T680 day cab designed to produce near-zero-emissions. Initial track and road testing is expected to start in the fourth quarter.
These two T680 tractors will be identical, with the exception of their power generation systems. Each truck will have an electric-only range of approximately 30 miles, and the on-board fuel – hydrogen or natural gas –will provide sufficient range for a full day in regional haul applications. Kenworth’s work on these programs is supported by grants of $2.1 million for each project from the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE), with Southern California’s South Coast Air Quality Management District (SCAQMD) as the prime applicant.
A third project received $4.8 million in funding from the California Air Resources Board (CARB), again with the SCAQMD as the prime applicant. Kenworth will build four additional, hybrid-electric T680 day cabs equipped with the Cummins Westport ISL G Near Zero NOx engine operating on compressed natural gas, and will also support customer field tests of these units in Southern California drayage operations.
Kenworth will build its first unit for this project in 2018. Kenworth engineers will be able to make design and system refinements to this 2018 unit based on data collected from this year’s real-world testing of the initial 2017 hybrid-electric T680.
All six prototype T680 day cab drayage tractors, produced as a result of these Kenworth programs, will transport freight from the Ports of Los Angeles and Long Beach to warehouses and railyards in the Los Angeles basin.
