Trident Energy and 42 Technology on crest of a wave

Offshore renewables enabler Trident Energy and product innovator 42 Technology have further enhanced the capabilities of a novel linear generator concept in an all-Cambridge UK collaboration.

The re-design, branded PowerPod II, represents a major advance for Trident Energy and its WaveDrive project, which is aimed at developing a generic power take-off (PTO) system for use in a broad range of wave energy converter (WEC) devices.

Trident’s WaveDrive project was awarded almost £0.5 million in development funding earlier this year from Wave Energy Scotland.

Steve Packard, CEO of Trident Energy, said: “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.

“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 converters and certain tidal energy devices, potentially enabling higher manufacturing volumes, lower cost and faster commercial deployment.

The new concept is similar in size to its predecessor but generates 50 per cent more electrical power on each stroke – helping converter developers to implement more cost-effective and competitive systems.

Trident, based at the Future Business Centre in Cambridge, has designed, built and tested linear generator control systems and advanced ‘wave to wire’ simulations – described as a world first which further builds on early collaborative work undertaken by Cambridge University.
