The objective of the project is to develop a multi-stage water turbine which can utilize different heights of water head on a common trubine wheel. The multi-stage technology will minimize the number of start/stop sequence on the turbine even if only one reservoir is sypplying water to the turbine, resulting in a high degree of utilization
The Seawave Slot-Cone Generator (SSG) concept
is an wave energy converter based on the wave overtopping principle utilizing a total
of three reservoirs placed on top of each other, in which the potential energy of the
incoming wave will be stored. The water captured in the reservoirs will then run through
the multi-stage turbine. Using multipl reservoirs will result in a high overall efficiency.
The SSG is built as a robust concrete structure with the turbine shaft and the gates controlling the water flow as virtually the only moving parts of the mechanical system.
The SSG concept makes use of the innovative patent pending multi-stage turbine developed
by WAVEenergy AS. The multi-stage turbine has the advantage to utilize different heights of water head on a common turbine wheel. The multi-stage technology will minimize the number of start/stop sequences on the turbine, even if only one water reservoir is suppling water to the turbine , resulting in a high degree of utilization.
In desember 2005 a development consortium with WAVEenergy AS as the project co-ordinator, will start a pilot project at the island of Kvitsøy, Norway.
The objective of the pilot project is to develop a full scale technical prototype of the SSG breakwater structure and install this on the west coast of the island of Kvitsøy in an 19 kW/m wave climate.
The objective of the pilot project is to demonstrate at full-scale, the operation of one moduel of the SSG wave energy converter in an 19 kW/m wave climate, including turbine, generator and control system, and to connect the system to the public grid for electricity production.
The participants in the EU project is:
-
WaveEnergy AS (co-ordinator)
-
Aalborg University, Hydraulic and Costal Engineering, Denmark
-
Technical University of Munich, Germany
-
Ganz Transelektro, Hungary
-
Municipality of Kvitsøy, Norway
-
Norwegian University of Science and Technology
-
IKM Gjertset Elektro, Norway
The Island of Kvitsøy is located in the Bokna fjord adjacent to the Norwegian North Sea.
The nearest major city is Stavanger at a distance of one houer by ferry and car.
The Kvitsoy municipality has 520 inhabitants and is one of 10,000 islands in Europe where wave energy can quickly be developed into a cost-effective energy production alternative to existing diesel generators.
The patented multi-reservoir concept ensures that a variety of waves are utilized for energy production, resulting in a high degree of efficiency.
MST Project
The objective of the project is to develop a multi-stage water turbine which can utilize different heights of water head on a common trubine wheel. The multi-stage technology will minimize the number of start/stop sequence on the turbine even if only one reservoir is sypplying water to the turbine, resulting in a high degree of utilization.
The MST project commenced in January 2005 and is in co-operation with NTNU (Norwegian University of Science and Technology). The Project is supported by the Renergi program of the Norwegian Research Council.
