First prototype is launched

Crestwings prototype Tordenskiold is launched in Kattegat in autumn 2018 northeast of the islands of Hirsholmene.

The purpose is to test the plant's anchorage and function at sea and confirm the expected production of energy.

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.

Crestwings technology is special

Crestwing has solved the biggest challenges of wave energy - the high costs producing the plants, the low power generation and the challenges of accidents. Crestwing is in no way similar to other wave energy plants and utilizes the energy of the waves in a unique way as the plant mainly utilizes atmospheric pressure for the production of energy.


It is easy to carry out service and

maintenance on Crestwing as you board the plant as a ship.

Power Take Off

The Power Take Off system is mechanical and converts about 90 percent of the absorbed energy into electricity.


Crestwing has developed a unique anchoring system that minimizes environmental impact on the ocean and the seabed.

Development phases

The basic idea behind the development of Crestwing has been to develop a wave energy plant that:

Is stable and safe on the sea.

Utilizes a high percentage of the incoming energy from the waves.

Efficiently transforms the absorbed energy into production of electricity.

Consider maintenance and service.
