20 years of research lead to successful trials of this wave energy converter

The piece of equipment, which has been dubbed a “submerged wave buoy”, is 7 meters high and has a diameter of 4 meters.

The Waveswing differs fundamentally from existing wave energy concepts and has a much higher power capture potential than floating objects of comparable size.

The device could work in extreme weather conditions

Waveswing can withstand harsh conditions in an offshore environment due to its underwater position and ability to winch deep under storm waves. The device could work in more extreme circumstances, including Force 10 gusts of windsays the company.

“The Waveswing features a single absorber design, with unique characteristics that make it ideal for remote power applications such as powering subsea oilfield assets and oceanographic monitoring,” said Gray.

The on-board winch and quick-connect anchor attachment allow for self-installation, while the single-point tension tether minimizes mooring spread.

The innovative operational concept and smart algorithms generate peak power capture per ton of structure, reducing expenses.

However, “for utility-scale energy, we believe the future lies in multi-absorber platforms that can achieve the scale necessary for wave energy to make a significant contribution to renewable energy supplies,” Gray said.

“We plan to develop platforms hosting up to twenty 500 kW units with a potential capacity of 10 MW per platform.”
