Overhead wires feed energy to trucks in California

Posted by K R on

Siemens has announced that an electrified highway demo is running on a highway stretch in the United States. Siemens and South Coast Air Quality Management District are keeping watch on the highway near two ports of Los Angeles and Long Beach. SCAQMD noted that heavy-duty trucks were the number one source of smog-forming emissions in Southern California. The company makes a case for why this is important to watch; similar to what many say about the effects of conventional road freight transport on the environment. That transport largely depends on combustion engines running on fossil fuel. The carbon dioxide, nitrogen oxide and particulate matter emissions put human health at risk and the environment in general. The one-mile demo, where three big-rig trucks hauling freight are running along the stretch of highway, is to demonstrate an eHighway system when applied to truck operations on public roads in an urban U.S. setting. The eHighway is in Carson, California. "This project will help us evaluate the feasibility of a zero-emission cargo movement system using overhead catenary wires," said Wayne Nastri, SCAQMD's executive officer. To connect the system, a sensor checks if the traffic lane is equipped with the contact line. The truck raises its pantograph, which positions itself to the overhead contact line. The pantograph can be easily connected to and disconnected from the contact wire at speeds ranging from 0 to 90 km/h. This is done automatically or, at a push of the button, manually.
