Powering Aquaculture with Wave Energy (RD162)


This project will see the creation and demonstration of a prototype wave energy converter able to be integrated into fish farms’ power networks, thus saving fuel and reducing carbon emissions.

Duration of Project:

18 months

Project Summary:

Aqua Power Technologies wave energy converter, MANTA, is a submerged drag actuated point absorber, designed to hang 15-20 meters below a float which is on the sea surface. As the float rides the peaks and troughs of waves, MANTA heaves up and down, which causes the wings to fold up and down, due to the drag generated by the large surface area of MANTA’s wings. So, as MANTA heaves up, the wings fold down, and as MANTA heaves down, the wings fold up. To convert the slow and high force wing motion into electricity a heavy-duty belt and pulley combination is used to rotate a generator.

Under this project, Aqua Power Technologies is aiming to build a prototype MANTA and demonstrate the technology on a live salmon farm off the west coast of Scotland. The MANTA machine will be integrated into the farms power network and the diesel and carbon savings measured, to assess the real-world economic case for the machine.
