The 80-meter vessel can carry 120 cars and 360 passengers. From 2015 onward, it will serve the route between Lavik and Oppedal, across the Sognefjord. The ship's batteries will be recharged in the breaks between crossings, a procedure which only takes 10 minutes.
The vessel currently serving this route uses approx one million liters of diesel a year and emits 2680 metric tons of carbon dioxide and 37 metric tons of nitrogen oxides. The electrically powered ferry was developed for submission to a competition organized by Norway's Ministry of Transport. As a reward for winning the competition, the shipping company Norled has been granted the license to operate the route until 2025.
The ferry has been specially designed to accommodate the requirements of an electric drive system. As a catamaran with two slim hulls, it offers less resistance in the water than a conventional vessel. Furthermore, the hulls are made of aluminum instead of steel, which is conventionally used. Rather than a diesel engine, the ferry is equipped with electric motors to drive the ship's two screws. These motors are powered by a battery weighing 10 metric tons.
These serve to recharge the ferry's battery during turnaround and are then themselves slowly recharged from the local grid.Hundreds of ferries link Norway's mainland to the islands off its coast and provide routes across its many fjords. Using today's battery and recharging technology, all crossings of up to 30 minutes in duration could be served by electrically powered vessels.

Tampering the current in a petri dish

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.
In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
Characterization of high-quality material reveals important details relevant to next generation nanoelectronic devices
Quantum mechanics is the field of physics governing the behavior of things on atomic scales, where things work very differently from our everyday world.
When current comes in discrete packages: Viennese scientists unravel the quantum properties of the carbon material graphene
In 2010 the Nobel Prize in physics was awarded for the discovery of the exceptional material graphene, which consists of a single layer of carbon atoms...
The trend-forward world of display technology relies on innovative materials and novel approaches to steadily advance the visual experience, for example through higher pixel densities, better contrast, larger formats or user-friendler design. Fraunhofer ISC’s newly developed materials for optics and electronics now broaden the application potential of next generation displays. Learn about lower cost-effective wet-chemical printing procedures and the new materials at the Fraunhofer ISC booth # 1021 in North Hall D during the SID International Symposium on Information Display held from 22 to 27 May 2016 at San Francisco’s Moscone Center.
Staphylococcus aureus usually is a formidable bacterial pathogen. Sometimes, however, weakened forms are found in the blood of patients. Researchers of the University of Würzburg have now identified one mutation responsible for that phenomenon.
Staphylococcus aureus is a bacterium that is frequently found on the human skin and in the nose where it usually behaves inconspicuously. However, once inside...
