Edinburgh University Tech Chosen for Innovative Wave Energy Project

The university-made technology will be put through performance and acceptance testing using representative wave data.

Wave energy company, Mocean Energy, has selected technology developed by the University of Edinburgh to help develop its first half-scale wave energy prototype.

Mocean Energy secured £3.3 million in funding from Wave Energy Scotland (WES) in January to develop and build a scale prototype of the company’s Blue Horizon wave machine – which is set to be deployed in Orkney next year.

The Edinburgh-based energy firm has chosen the University’s C-GEN technology to provide the power take-off (PTO) system for its utility-scale demonstrator.

C-GEN is a highly efficient direct-drive generator that can operate in a range of wave conditions no matter how treacherous.

Researchers at the University are also working alongside WES as part of a separate project to further develop and demonstrate the technology.

Commenting on the announcement, Professor Markus Mueller from the University of Edinburgh said: “The integration of the C-GEN generator into Mocean’s wave energy device is an exciting development, pushing forward the benefits of the modular direct-drive generator from marine test rig to marine environment operation.

“This programme will allow us to industrialise the design and manufacture of C-GEN for marine renewable applications and demonstrate C-GEN in a real environment, at a relevant scale and under realistic load profiles.”

Moving forward, the two teams will build a test rig, which is set to be tested at a facility in Rosyth. The University-made technology will be put through performance and acceptance testing using representative wave data, Mocean Energy confirmed.

Cameron McNatt, managing director at Mocean Energy, said: “To date, our focus has been on the hydrodynamic and mechanical performance of the Blue Horizon.

“Blue Horizon is a hinged raft with a unique geometry which flexes in two dimensions via a relatively slow-moving single hinge. C-GEN is a good match for us because it delivers high efficiencies in the right range of speeds.”

McNatt added: “Our test programme will ensure we optimise the performance of both technologies to extract the maximum mechanical energy from our operational machine.”
