Siemens tests eHighway system in California

Siemens is to conduct trials on a two-mile stretch of highway after installing a catenary system for electric and hybrid trucks in the vicinity of the largest US ports of Los Angeles and Long Beach.

In the context of the research project ENUBA (Electromobility in heavy commercial vehicles to reduce the environmental impact on densely populated areas), Siemens produced an holistic concept for the electrification of HGV traffic by means catenaries and to test the technical feasibility of the system on a specially built test track in the north of Berlin, Germany.

The company was awarded the associated contract by Southern California's South Coast Air Quality Management District (SCAQMD). The objective is to completely eliminate local emissions such as nitrogen oxides and to reduce the consumption of fossil fuels and cut the operating costs of trucks.

The test results should be available in the summer of 2016, and will indicate the suitability of the systems for future commercial use. The ports of Los Angeles and Long Beach are seeking an emission-free solution ("Zero Emission I-710 Project") for a section of Highway 710, which carries a high proportion of shuttle truck traffic. The 30 kilometer route links the two ocean ports and the railroad transshipment centers inland.

As part of the installation of the eHighway systems, two lanes of Alameda Street in the city of Carson, California, are being electrified via a catenary system. On the road, E-trucks equipped with hybrid drive and smart current collectors will be supplied with electricity from catenaries, offering local zero-emission operation.

In conjunction with vehicle manufacturer Mack, a member of the Volvo Group, and local truck conversion specialists, Siemens is developing up to four demonstration vehicles. The smart current collectors permit overtaking maneuvers and automatic hook-up and disconnection at speeds up to 90 km/h. On normal roads without overhead lines the vehicles make use of a hybrid system which can be operated alternatively with diesel, compressed natural gas or via a battery.

"Our highway technology eliminates local emissions and is an economically attractive solution for freight transport on shuttle truck routes," says Matthias Schlelein, head of Siemens Division Mobility and Logistics in the USA. "Long Beach and Los Angeles, the two US ports generating the most traffic, can benefit hugely from our technology."

"This project will help us evaluate the feasibility of a zero-emission cargo movement system using overhead catenaries," said Barry Wallerstein, SCAQMD's executive officer. "Southern California's air pollution is so severe that it needs, among other strategies, zero- and near-zero emission goods movement technologies to achieve clean air standards."

"I'm happy to see the Los Angeles region leading the way in bringing cutting edge technology to an increasingly important economic center," said Los Angeles Councilman Joe Buscaino. "The eHighway project is a great example of how electricity can help power the next generation of transportation systems while also providing cleaner air for our citizens in the process."

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
