DeltaStream tidal power Pembrokeshire trial approved  

Posted by Big Gav in , , , , ,

The BBC reports another British tidal power project has reached pilot stage - DeltaStream tidal power Pembrokeshire trial approved.

A tidal power scheme designed to generate electricity for 1,000 homes in Pembrokeshire has been approved for a 12-month trial.

The 1.2MW project at Ramsey Sound, near St Davids, features three generators that sit on a triangular frame.

Invented by Pembrokeshire engineer Richard Ayre, the project has more than £500,000 in EU grants.

The DeltaStream device project has landed consents from both the UK and the assembly government.

Cardiff-based Tidal Energy Ltd claims its tidal generator is at the cutting edge of green technology, with three separate horizontal axis turbines mounted on a common triangular frame.

Each turbine has a 15m diameter rotor which turns in the tidal flow and can also turn with the tide, generating electricity on both the ebb and flood tides.

The firm said the device would be easy to manufacture, does not require drilling or piling into the seabed and would have a minimum environmental impact.
