We have a long track record of research into extracting power from waves and have developed a wide range of devices, from inception to scaled testing in our excellent wave tank facilities. We are currently investigating the potential of multi-axis wave energy converters that could improve power capture for a new generation of devices.
Our research focuses on devices for tidal stream energy generation. One of our latest projects is investigating multi-element high-lift devices. These will offer significantly improved operational performance, augmenting the overall energy yield in both spring and neap tidal cycles. We are also involved with a number of regional tidal barrage proposals.
Hydropower turbines produce one-fifth of the entire world's electricity. Our research focuses on exploiting hydropower by converting water pressure into air pressure. This allows the use of much smaller, less expensive and faster turbines running in the air, eliminating the need for a step-up gearbox to drive the generator. The system under development uses siphons, bridging the weir or barrage. The aeration of the water makes the system attractive for use in water treatment plants.
