Danish wave energy developer Wavepiston has redeployed its prototype wave energy system off the west coast of Denmark.

Wavepiston’s wave energy system hit the waters of DanWEC testing site on May 11, 2017.

The anchors for the system have been tested at 20 tons for 20 minutes, and the first energy collector has been mounted and running, according to Wavepiston.

The second energy collector is currently being assembled ahead of the upcoming deployment.

Wavepiston wave energy prototype is comprised of a steel wire stretched between two anchored buoys.

The 120-meter long string has 8 optimized energy collectors planned to be mounted onboard. The device works when waves roll along the wire moving the plates back and forth.

The moving plates pump seawater into pipe which leads it to a turbine that produces electricity.

The expected output of the prototype is 12kW.

It was developed by a consortium which in addition to Wavepiston includes the Technical University of Denmark, Global Maritime Vryhof, and Nurmi Cylinders.
