South Coast AQMD Awards Siemens a Contract to Test
Three Truck Types on a Two-Mile Stretch of Road in Carson,
Siemens Cites Volvo Group/Mack, TransPower Involved Too
Siemens is to conduct demonstrations of electric trucks drawing power from overhead lines in the vicinity of the largest U.S. ports of Los Angeles and Long Beach.
Siemens says it will install a catenary system along two lanes of a two-mile stretch of Alameda Street Carson, Calif.
It’s another step in a long-gestating project to reduce pollution from trucks serving the ports, with the eventual goal being the installation of catenary overhead power lines along the busy Interstate 710 highway connecting the port with inland customers and depots.
SCAQMD and CEC
The concept, also known as Zetech, has been the subject of several detailed reports, including an effort by Fleets & Fuels publisher GNA/Gladstein, Neandross & Associates in Spring 2012 (F&F, April 22, 2012).
The lead agency for the current Siemens work is the South Coast Air Quality Management District. The California Energy Commission has also supported the project (F&F, June 18, 2013).
Siemens says that it’s working with the Volvo Group, via its Mack Trucks subsidiary, on a demonstration vehicle for the project. Siemens notes that it “also is supplying current collectors, the technology that allows trucks to connect and disconnect from the catenary system at any speed, to local California truck integrators whose vehicles will also be part of the demonstration.”
TransPower for Two Trucks
Two trucks are to be supplied by San Diego-based TransPower: a full battery electric vehicle modified to draw power from the catenary/pantograph system, and a battery-dominant CNG-boosted hybrid that will be able to travel as far as 200 miles on a charge (see this week’s related F&F report).
A fourth truck maybe added, advises Joe Impullitti of SCAQMD.
“Smart current collectors enable overtaking maneuvers and automatic connecting as well as disconnecting at speeds up to 90 kilometer per hour” (56 mph), Siemens says. “On roads without overhead lines the vehicles make use of a hybrid system which can be powered alternatively with diesel, compressed natural gas or via an onboard battery.”
Results in the Summer of 2016
Test results should be available in the summer of 2016, the company says, “and will indicate the suitability of the systems for future commercial use.”
According to Matthias Schlelein, who heads Siemens mobility and logistics unit in the U.S., “Our eHighway technology eliminates local emissions and is an economically attractive solution for freight transport on shuttle truck routes.”
“Long Beach and Los Angeles, the two U.S. ports generating the most traffic, can benefit hugely from our technology,” Schlelein says in the latest announcement.
