WORLD’s FIRST ELECTRIC PASSENGER SHIP BASED ON SUPERCAPACITOR TECHNOLOGY

The pressure to find alternative fuels and hence consequently also alternative drives, driven by both emissions legislation and resulting commercial pressures that threatens to drive up the cost of all kinds of fuels, is as well impacting on the ship design market. Another new electric passenger vessel, the "Ar Vag Tredan" ordered by Lorient City Council (Brittany, France) is most definitely a technological breakthrough for the design and construction of “zero emission” ships.
This 22 meter vessel is aimed at passenger transportation in the intracostals waterways around Lorient, from the city centre to the entrance of the roadstead, two and a half nautical miles away. This ship represent a significant improvement compared to existing fully electric ships operated on short and distances in harbour areas or inland waterways.
Based on supercapacitor technology developed and patented by STX Europe, the naval architecture and ship design of the new ferry have been developed by the design company Stirling Design International (SDI) in Nantes. The Shipyard based in Lanester benefitted from the significant expertise of passenger ship design gathered by SDI during the last decades. This partnership allowed the STX shipyard to be selected after a long competitive process, part of this government procurement program. This unique vessel was delivered to “Cap Lorient” in October 2012.
Energy storage based on supercapacitors leaded to re-design entirely the ship architecture, from watertight compartment definition, lightship weight distribution, electric azimuth propellers from Masson marine, as well as ship hull form. This 22.1 meter long catamaran by 7.2 meter wide for a design draft of 1.5 meter will have a max speed, loaded, of 10 knots. This has been confirmed by towing tests at the towing tank facilities of HSVA (Hamburger Schiffbau-Versuchsanstalt). The launch will be able to accommodate 150 passengers including three passengers with disabilities, and 10 bikes.

The supercapacitors capacitiy is enough for one round trip. Reloading is done during unloading and loading of the passengers, by shore-power and takes only 4 minutes. The voltage is of 400V and is connected  via a two-pin plug manually at the stem of the ferry.
This new generation of vessels will allow a significant reduction in ship emissions with zero direct emission in electric mode, with no diesel engine in operation. Sound level and vibration in the passenger area and in the environment will be significantly reduced.
A special care has been brought to detail design, allowing reduction of thermic loads on the glassing of the passenger lounge and wheelhouse. Use of natural ventilation has been used throughout the ship with numerous hatches on the roof. Photovoltaic panels contribute as well to improve the electrical autonomy of the vessel during navigation.
Ar VAG Tredan has been classified by Bureau Veritas as CLEAN SHIP.

THIS IS A GOOD NEWS FOR SUPERCATIOR APPLICATIONS AND ENTHUSIASTS LIKE ME.
I HAVE BEEN FOLLOWING THE LATEST NEWS ABOUT SUPECAPACITOR DEVELOPMENTS AND APPLICATIONS AND THIS IS THE FIRST TIME I HEARD ABOUT THIS USE OF THE SUPERCAPACITOR IN SHIPS.

HOPEFULLY MORE APPLICATIONS OF THE SUPERCAPACITOR CAN BE USED IN OTHER USAGE AND PARTICULARLY FOR LASER's POWER SOURCE AND THE LIKES.

CONGRATULATIONS.

REGARDS,
