UK-based Trident Energy has improved the performance of its linear generator concept with the help of a technology optimisation project from 42 Technology.

The re-designed concept, PowerPod II, is a major advance for the company and its WaveDrive project which aims to develop a generic power take-off (PTO) system for use in a range of wave energy converter (WEC) devices.

“42 Technology has undertaken a detailed design review of Trident’s existing PowerPod linear generator and has successfully optimised it for performance, robustness and manufacturability,” said Steve Packard, CEO of Trident Energy.

He added: “The design improvements and project outcomes have exceeded expectations and the two companies are now progressing to detailed design of the new linear generator technology.”

The new PowerPod II concept is based on a single generic design that can be adapted for use in different types of wave energy convertors.

It is similar in size to its previous models but generates 50% more electrical power on each stroke, this helps developers implement more cost-effective and competitive systems.

A magnetic stack configuration has been optimised to allow the linear generator to operate horizontally. This widens the available options for installation and operators.

“I am pleased to see the improvements to this technology’s performance. This is a success for Trident and an excellent contribution to the advancement of wave technology,” said Tim Hurst, managing director of Wave Energy Scotland (WES).

Trident’s WaveDrive project was awarded approximately £0.5 in development finding earlier this year from WES as a Stage Two project in its PTO innovation call.
