Danish wave energy device nears commercialization thanks to new grants and government support

Danish company Crestwing has received funding from Den Danske Maritime Fond to support the technical development of Tordenskiold, a prototype of its wave energy device.

Thanks to this funding and support from the Danish government under the EUDP (Det Energiteknologiske Udviklings- og Demonstrationsprogram), the device is now close to being introduced to the market.

The prototype device is 30 meters long, 7.5 meters wide and weighs 65 tons. The device is a type of floating wave energy device damper that operates parallel to the direction of the wave, with a hull designed like a ship’s hull.

The devices capture energy from the relative motion of two arms as a wave passes them. Crestwing says the company plans to sell its device on a commercial scale to domestic and foreign energy companies.

“We look forward to the new collaboration with the Danish Maritime Fund, as well as the continued collaboration with EUDP. Their support is essential to enable Crestwing to achieve commercialisation,” Crestwing said in a post on social media.

According to Crestwing, with the completion of the prototype design, the company is also preparing to manufacture and deliver its first 2.5-MW C-WEC, inviting potential investors and partners to join it on the journey.

In November 2020, the company completed the second sea test campaign of its Tordenskiold wave energy harvesting prototype.

In other related news, in May 2023, Crestwing made progress in developing its wave energy technology as part of a joint project funded by the EUDP.

With support of €980,000 from the EUDP, Crestwing has partnered with Aalborg University (AAU), marine engineering company Shipcon and software and engineering company Logimatic Engineering to demonstrate market-ready wave energy technology.
