Catenary Truck Demonstrated

A Mack truck prototype equipped with a proprietary and fully integrated plug-in hybrid electric driveline recently participated in a zero-emission eHighway demonstration in Carson, Calif.

The demo was conducted near the ports of Los Angeles and Long Beach as part of a project with Siemens and sponsored by the South Coast Air Quality Management District (SCAQMD). The goal of the project is to reduce air pollution at freight-intensive locations, such as the ports of Los Angeles and Long Beach, the two largest ports in the U.S.

 “Mack continuously investigates alternative solutions to diesel, and the catenary system is just one of a number of projects in which we are currently involved,” said Jonathan Randall, Mack senior vice president of North American sales.

Siemens installed the eHighway infrastructure, which covers one mile of select lanes of a highway with a catenary system similar to those used to power trolleys or streetcars.

The Mack prototype used in the November demonstrations is a Mack Pinnacle DayCab model equipped with a proprietary plug-in hybrid electric driveline. The Mack truck can connect to the overhead contact lines and transfer energy to the truck’s electric driveline thanks to a current collector supplied by Siemens.

Mack said it has investigated several other solutions for reducing greenhouse gas and criteria pollutant emissions including a plug-in hybrid electric powertrain and the use of alternative fuels such as dimethyl ether (DME).
