Crestwings prototype Tordenskiold was launched in Kattegat in autumn 2018 northeast of the islands of Hirsholmene in Frederikshavn Municipality. Tordenskiold measures 30 x 7.5 m with a weight of 65 tons. The purpose is to test the plant's anchorage and function at sea and confirm the expected production of energy. The plant will be tested in this position through the year 2020.
It has taken Crestwing from 2005 to get to the point of a prototype that can easily be scaled up and produced. The price to reach so far has been about 30 million DKK. This indicates that Crestwing can produce plants and energy at a kWh price, which corresponds to the production of other renewable energy types.
Tordenskiold is in scale 1:2 of a similar plant designed to exploit the power and size of the waves in the North Sea. Calculations and tests are made at Aalborg University (AAU) and the Danish Hydraulic Institute (DHI). Read more about Crestwing's developmental phases.
While Tordenskiold is located on site next to Hirsholmene, the entire plant is monitored and tested, the size of the waves measured, and there is a continuously development on PTO, hinges and anchoring. Out of this, a report will provide a basis for the development of the next generation of the plant.
The following measurements can be monitored from land:
Alongside the tests and documentation of Tordenskiolds effectiveness and function at the site in Kattegat, the company is working on the following:
By 2020 and 2021, Crestwing plans to design and produce at first one plant measuring 70 X 18 m, which will be located in the North Sea. Thereafter produce another two plants, so the three plants will form the first park of Crestwing wave energy plants.
